Having A Mellow Dog Is Not Insurance That A Coyote Will Not Approach

2016-04-12“My dog is the mildest, shiest dog I’ve ever known. She startles at everything — runs from the drop of a pin. Yet, two coyotes approached her anyway, dashing in our direction from the distance. At first I thought they were two dogs who wanted to play, so I didn’t do anything, but as they hurried closer, I realized my mistake too late.

They headed immediately for her rear end.  She had been unleashed, but fortunately she didn’t run off. I grabbed her and leashed her. I kept my eyes on the coyotes which is what seemed to keep them away as I slowly backed out of the situation and then walked away. It was very frightening.”

A coyote doesn’t care if your dog is aggressive or mild — all the coyote cares about is that the dog is in its space. In fact, it is often the calmer dogs that coyotes attempt to *message*, either through body language (which most dogs can’t read) or more directly by nipping the dog’s haunches if the coyote can get close enough. Coyotes may pick a milder dog to message simply because they are able to do so — it’s easier — whereas it is more dangerous, in their eyes, to message an aggressive dog. So a dog’s mildness is not a factor in attracting a coyote’s interest to a dog. Whether calm or barking aggressively and lunging at them, any dog could be “messaged” to move it away. Remember that coyotes would do the same for intruder coyotes — this is a function of their territorial behavior.

It appears that this particular dog and owner happened upon one the coyotes’ favorite “lookout” spots — folks had seen the coyotes often relaxing in this spot. The dog was standing there, in a solidly planted stance, as if he were claiming the spot, staring at the coyotes as they came in closer. Another contributing factor may be that these coyotes might have just been chased by another dog — dogs chase coyotes often. I’ve noticed  that sometimes coyotes are more eager to “message” other dogs when they themselves have just been provoked by intrusive dogs, and I’ve seen them choose a milder dog to do so. This can be prevented by moving away from coyotes the minute you see them: doing so shows them that you are not interested in them and not there to threaten them or fight for the spot.

Please always remain aware and vigilant when you walk your dog in a park with coyotes. If this owner had been aware from the start, she could have leashed and moved away as the coyotes approached — this is what the coyotes wanted, and it is something that is easy to do. And it would have saved the dog-owner from a lot of unnecessary fear and anxiety.

Responding to Recent Postings on Social Media: A Recap of Some Urban Coyote Behaviors and Some Explanations

This posting is a slightly revised and expanded version, with photos, of what was originally written for, and posted on, Bernalwood.com on May 27th.

We have coyotes in most of our parks here in San Francisco, and most folks I’ve spoken with are thrilled about it!  Enjoy it and respect its wildness! At the same time, there are some people, especially pet owners, who are not so thrilled. Here is some information I’ve put together about coyotes, much of it based on my own observations, as a response to concerns and comments which have appeared in some of the social media recently. This is information that applies to urban coyotes everywhere, not just here in SF.


coyotes in our parks

coyotes in our parks

Most parks in San Francisco have one stable resident family, or a loner. Coyotes are not “pack” animals of unrelated individuals. Families “claim” territories which they “own” from which they exclude other coyotes — this is what keeps the population density down. They trek through the neighborhoods every night, during the early morning or early evening hours — and, more rarely, during the brightest hours of the day — marking their territories to keep other coyotes out and looking for hunting opportunities. Studies show that in urban areas, there is generally about one coyote per square mile — a family of 4 would require about 4 square miles. You will always be seeing the same individual coyotes in any particular area.

Although we have parks with loner coyotes, most parks have mated pairs with families. Coyotes mate for life, and both parents raise the young. Coyotes mate in January or February and produce young in April — births occur only once a year. 

The number of family members fluctuates up and down continually over time. In one park, it went something like this: 2-5-3-4-2. The fluctuation is due to new pups, and then to their dispersal or deaths. There is only about a 30% survival rate of pups during their first year — disease and nutritional issues take their toll.

When it’s time for youngsters to “disperse”, the parents will drive them out, or they may just pick-up-and-go. This usually occurs between one and two, and sometimes three years of age, and it occurs throughout the year — there is no “dispersal season”. However, the breeding adult pair will remain in the same territory over many years. Interestingly, wolves will actually kill their own kin in order to preserve their own statuses and territorial rights. I’ve not seen this in coyotes, but I have seen the altercations that drive coyotes out of their birth territories.

Cars are urban coyotes’ chief cause of death — please drive carefully! They often trek on our traffic grid — it’s often the “path of least resistance”.  A few days ago, in our Diamond Heights neighborhood, a car swerved right into someone’s house to avoid hitting a coyote during the early morning hours.

As the individuals in a family mature, some of them may go through phases of what might be called more “assertive”  or “insistent” behavior, such as: following or running in the direction of a dog. During pupping season, the assertiveness is strongest, with coyotes even approaching and possibly even nipping at a dog’s haunches. These are coyote “messaging” behaviors: coyotes want dogs to move on and to know the territory is taken. These behaviors don’t “define” a coyote, and they don’t last. Think of these as phases in a teenager’s life, or in a parent’s life — there’s an ebb and flow to behaviors for each coyote, often based on what is going on within the coyote’s individual family: Are there new pups? Is there increased sibling rivalry? Are parents having issues with the offspring, or trying to get one to disperse? I’ve seen no evidence to indicate that such behaviors build up towards more aggressiveness. Many of the more apparently “assertive” behaviors, both in juveniles and adults, are based solely on circumstances and happenstance encounters, so keep your distance.


trekking through the neighborhood

A substantial increase in “sightings” doesn’t necessarily translate into a spike in the coyote population, though this is what many people assume. Again, increased sightings could be due to their current family dynamics which may cause individuals to wander farther afield.

Unusual weather conditions can have an effect on sightings. San Francisco has just been through a four-year drought. Drought conditions cause coyotes to hunt further afield and for longer hours. They become more visible to humans and more prone to incidents during these times when their activity overlaps with ours. It takes 8 full months for an ecosystem to recover from a drought.

Human changes to the environment, including new construction, will affect coyotes in an area. In San Francisco, coyotes may be lingering longer in neighborhoods recently, and therefore be seen more, because of the current program of thinning and eliminating dense and protective thickets in the parks, reducing coyotes’ normal secure habitat.  Stopping the destruction of the habitat, and compensating for the exceptional weather or drought in various ways until the ecosystem has recovered, both are steps that could be taken to reduce sightings, and possible dog/coyote encounters, and coyotes’ spending the past-twilight hours in neighborhoods.


feeding coyotes is not good

feeding coyotes is not good

Please don’t feed the coyotes. Feeding breaks down the barrier that keeps coyotes wild. If they become food conditioned  — which is different from “habituation” (see below) — problems could develop, including approaching people, which increases the chances for a negative incident to occur. Feeding them also encourages them to hang around yards where people don’t want them.

Coyotes are opportunistic eaters, which means they can eat almost anything, but their preference in San Francisco is for gophers, squirrels and voles, which they eat whole: they need the meat, muscle, bones, fur — all of it — to nourish themselves properly. They also eat fruit, nuts, bugs, weak or juvenile raccoons, skunks, opossums, and possibly snakes. They prefer their whole foods over human-made foods, but if that human food is available, they’ll try it. And they will eat the occasional cat or small dog if circumstances are right — they don’t know who is a pet and who isn’t. Don’t create the right circumstances that could add your pet to the food chain. Please protect your pets by not allowing them to roam free and by supervising them closely when out-of-doors.

As top predators to an area, coyotes have helped rebalance the environment: they control rodents and some mesopredators, such as opossums, skunks and raccoons.


a habituated coyote is not a dangerous coyote

a habituated coyote is not a dangerous coyote

Urban coyotes do not “fear” humans — that is an incorrect term. Rather they are “wary” of humans. This means that, although a coyote won’t flee lickety-split in fear when they see a human, they nonetheless will maintain distance and not approach us. And we, in turn, need to respect them and their wildness by keeping as far away from them as we can. “Habituation” is a normal progression in urban areas — you cannot prevent it because you cannot stop coyotes from seeing humans on a daily basis — they get used to seeing us. A habituated coyote is not a dangerous animal. In fact, the term “habituation” was first used to describe bears as being more dangerous if they got used to people and lost fear of us. This assumption has been turned on its head: scientists now know that bears who are habituated tend to ignore humans, whereas bears who have never seen humans become reactive. In Africa, to make gorillas less reactive to humans, for the tourist trade, people purposefully habituate them — they become less dangerous.

Coyotes also habituate to “hazing” tactics, which is why such tactics should not be used if a coyote is way out in left field. Scaring off a coyote should be used sparingly. It should be reserved for when a coyote has come too close to you. It is a useless tactic unless the coyote is closer than 50 or so feet to you, which generally delineates its critical distance for discomfort.

Note that “habituation” is different from “food conditioning”. When visibly feeding or hand-feeding a coyote, you are conditioning it to approach humans. Don’t feed coyotes.

Whereas coyotes don’t approach humans, dogs are a different story because of territorial issues and because of prey issues. In many ways, coyotes and dogs look alike, but coyotes and dogs are naturally antagonistic towards each other. Remember that coyotes keep other coyotes out of their territories. Coyotes are also both curious and suspicious of dogs: they may feel compelled to come in closer to investigate. Always supervise your pets to prevent incidents: the minute you see a coyote, leash and go in the other direction. Most dogs have a tendency to go chasing after coyotes. Please don’t allow your dog to do this.

coyote messaging a dog — the dog should have been kept away from the coyote

Coyotes have approached dogs. If they get too close, they could either grab a small dog or “message” a larger dog who the coyote considers a threat to its territory or its personal space. They can only do this when they get close enough. Don’t let them. You can prevent an incident by keeping your dog away from coyotes in the first place, by leashing when you see one, and by walking away from it. It’s no different than when you encounter a skunk with its tail up: keep your dog off of it, and move away from it.

 IF, inadvertently or by surprise, a coyote gets too close, that is when to scare it off, otherwise just walk away without running: see http://baynature.org/article/how-to-get-along-with-coyotes-as-pups-venture-out/

Coyotes may follow dogs to find out what the dog is doing and where it is going (they do the same to non-family coyotes). If you and your dog are moving away from the coyote, and away from any denning site, the coyote soon will no longer follow. If you don’t want the coyote to follow at all, toss a small stone in its direction (not at it), and/or approach it (but don’t get too close) using your own blatantly angry body language and angry yelling. Noise alone, or waving flailing arms, is not always effective in making a coyote move — something has to move  towards the coyote. And it isn’t going to help if you are too far away. You’ve got to get within the coyote’s critical distance — at most 50 feet — and you have to be assertive about it. Walking towards the coyote while slapping a newspaper viciously on your thigh works, but tossing stones towards it is probably more effective. However — and this is a very important “however” — if the coyote doesn’t budge, it is probably protecting a nearby den site. In this case, turn around and leave. Do not provoke an incident. See the above link in Bay Nature.

It’s always best to be proactive in keeping a coyote away. The minute you see a coyote, leash up and move away from it, and know how to shoo it off effectively if it comes closer to you than 50 feet.

Note that practically all scratches or bites by coyotes to humans are due to feeding the coyote, or to an owner getting him/herself between a coyote and a pet, so don’t do these things. And, never run from a coyote: this activity actually initiates the chase response in a coyote who may also nip at your heels. They also sometimes nip at car tires when the car is in motion. The phenomena is called “motion reactivity”.


Encounter: the dog chased the coyote and the coyote stood up for itself

Encounter: the dog chased the coyote and the coyote stood up for itself

Encounters CAN be scary if you are unprepared and don’t know what to expect or what to do. Please learn what coyotes are like, not what you think they “should” be like — for instance, that they don’t “fear” humans but are “wary” of them, and not that “coyotes should be heard and not seen”. By knowing their true normal behaviors, and by knowing what to do *IF* they approach your dog, you will be informed and you will not be so fearful. For starters, watch the video, Coyotes As Neighbors:  https://youtu.be/euG7R11aXq0, which will spell out normal coyote behavior and what you can do to keep coyotes away from a pet.


The number one method of managing coyotes for coexistence is through human education and human behavior modification: that is what this posting is trying to help with. These have been shown to be extremely effective. The City of San Francisco has been lax in putting out signs or getting educational material to folks. Some of us have been filling the void, getting material, information and guidelines out to people, but as individuals or as small organizations, we have not been able to reach everyone. Please visit coyotecoexistence.com for specific information, and  coyoteyipps.com.

Many cities have coexistence policies — they all work when folks abide by the guidelines. BUT, as with car driving laws, even if you know them and follow them, there will be some fender-benders that might be frightening. We have fewer than 100 coyotes in the City; the number of dogs is in the 250,000s. There is bound to be an incident now and then.

The number of real coyote incidents in the City is not many. There have been less than a handful of dog fatalities by coyotes — all were unleashed small dogs in known coyote areas — all were preventable. There have been many incidents of people being frightened and reporting “attacks” on their dogs. Few if any of these attacks were reported on a questionnaire which would tease out what actually occurred. Instead, these incidents have been spelled out on the social media with warnings of doom that is awaiting us all.

Most of the sightings of coyotes have been reported as charming. But there have been some fearful encounters, and recently groups of dog owners in some of the parks have turned decidedly against them. Social media tends to perpetuate, spread and amplify the fears, and encounters are inevitably worded as deliberate “aggressive attacks”. For instance, recently, there was a report of an attempted “attack” on a dog at 5:30 in the morning. However, a lone coyote, who weighs 35 pounds, is not going to “attack” a 130 pound Mastiff… Coyotes may watch dogs, follow, or hurry in your direction for many reasons, including curiosity, or investigation. They may jump up and down because of anxiety. These are not “attacks”, nor are they “attempted attacks”. Hopefully, by learning about coyotes, we can diminish the very real feeling of fear which comes from not knowing what is going on.

Our Animal Care and Control Department has had many people report “aggressive” coyotes: but when questioned further, the majority of these reports were of a coyote just standing, or doing nothing but looking at the purported victim.

Two years ago I watched a man, straight faced, tell me that he had been frightened “out-of-his-wits” by a monster 100-pound coyote just a few moments before seeing me. He was visibly shaken. He hadn’t seen me watching the whole incident a little way down the path. The incident involved his dog chasing a coyote. The coyote turned around to face the dog. When the dog ran back to its owner, the coyote proceeded on to where it had been going. But the owner was left frightened, and justified his fright by saying it was a “monster 100-pound coyote”. If the dog had been leashed, the incident would not have happened. It happened in a park where everyone knows there are coyotes.

It’s Not A Good Idea To Let Your Dog “Play” With Coyotes

It is best not to let dogs “play” with coyotes. At Bernal Heights (a neighborhood in San Francisco) about 9 years ago there was a single little female coyote who had chosen ONE of the dogs to frolic with: the coyote and the dog learned to know what to expect from each other and they acted accordingly. This was a lone coyote — a youngster who craved company and would allow herself several minutes of such play every day before disappearing into the bushes. This behavior became a daily occurrence over several weeks. The activity was considered “sweet” and “benign” by some of the onlookers. But, in fact, it broke down barriers that serve to protect both wildlife and dogs.

Dogs and coyotes almost universally do not like each other. This is because of territorial concerns. Coyotes do not allow non-family coyotes into their territories except for passing-through. In the recent videos I saw of dog/coyote interactions at Pine Lake, there was chasing of a coyote by a dog and then vice-versa. The dog owner should not allow his/her dog to chase coyotes. This was not play. The coyotes were assessing what the dog could do by playing a game of oneupmanship which, at this point, seemed, indeed, to border on play. The coyotes were figuring out where in their hierarchy the dog might fit. But the apparent “play” could quickly deteriorate into a situation which could be dangerous for the dog involved, and for other dogs who are around, AND for the coyote. The instinct of the coyote is to defend itself and not let other animals close to itself. A larger dog could easily maim a coyote — they do it all the time where there is coyote penning — and a small dog can easily be given the same treatment as any other animal of prey — no different from a skunk or squirrel or raccoon. And the coyote could message the dog with a nip to the haunches to get it to leave it alone, as seen in the photos here.

In addition, once a coyote becomes accustomed to intermingling with dogs — and therefore people — you are setting up a situation that has the potential for the coyote to approach people. In fact, coyotes and dogs have bitten people trying to break up a fight. Once a coyote has bitten a person, his fate is the death chamber. Here, again, there is a problem, because it’s hard to find the “right” coyote, so often a number of coyotes will be eliminated to insure that “the culprit” is caught. But of course, it wasn’t the coyote’s fault, it was the human’s fault who allowed a situation to occur in the first place.

So, please keep your dogs leashed if they like going after coyotes. It is the dog owner’s responsibility to do so. If a coyote approaches dogs, it is the responsibility of the dog owners to shoo it off. Please watch the demonstration of how to do this on the YouTube video, “Coyotes As Neighbors”: https://youtu.be/euG7R11aXq0.

Dog Chases Coyote, Coyote Chases Back, Walkers Cheer For Coyote!

dog chases coyote

What first caught my attention on this foggy San Francisco morning was a dog running at ultra-high speed down an embankment. Then I heard someone yelling for his dog, with the tell-tale panicky tone which is always a dead-giveaway for what is going on. The dog was a young, small German Shepherd, maybe 70 pounds, while the coyote it was chasing was a small 30 pounder. The dog was persistent and fast, but the coyote was faster. They raced around a large field several times while onlookers froze, wishing the dog would stop.

dog and coyote face each other

The dog would not respond to his owner’s frantic calls. The coyote finally stopped and stood still, which left the dog in the lurch — what to do now? Each animal looked at the other: the coyote was assessing his pursuer. Coyotes can read a dog’s character and intentions visually. One look at the German Shepherd told the coyote that this animal was all bluff. But all bluff or not, the coyote did NOT like being chased. Now the tables were turned. The dog, seeing that the coyote seriously meant business, began running away — fast, lickety-split, with its tail tucked under. The sullen bystanders suddenly perked up and cheered for the coyote: “Yay, Coyote! Way to go!”

coyote chases back

At this point, the dog decided to take refuge next to its owner, and as it reached its owner, the coyote stopped and turned to go the other way. The coyote, who simply needed to message the dog to leave him alone, would not get any closer to the human owner. Most unleashed dogs, by the way, will chase a coyote the minute they see it. The owner gave the dog a thorough body-check for nips: there had been none — this time. Hopefully the dog was sorry and won’t do it again, but often it takes a good nip before some dogs learn to leave coyotes alone.

Coyote “Attacks” and the Media, OR “Messaging”

The following news item and video (click on the link) serve as a departure point for exposing the truth about most reported “attacks” by coyotes, and for explaining coyote “messaging”: “Caught On Camera: Dog Attacked By Coyote”.

Although the video purports to show an “attack”, it does not do so. By calling this an “attack”, the article is creating a news story through sensationalist hype and playing on people’s fears. It sells well, it’s exciting, and it raises the fear level to a frenzy that, for most folks, justifies killing coyotes. It is irresponsible journalism, but it is how the press has been handling almost all reports regarding coyotes. We have suggested to journalists and news stations that they please contact biologists trained specifically in coyote behavior to help them get correct information out to the public, and this article does at least list what folks can do when they see a coyote. At the same time it calls what happened an “attack” which is blatantly incorrect.

What the video does show is a few seconds of a dog running from a coyote chasing it. Also, the article reports a couple of sightings, and that the dog, Lexus, came home with a few scratches. These are the facts from which this “attack” article is spun. But the dog wasn’t maimed, he wasn’t hurt, and there’s no proof at all that he was “attacked”. That he “got away with his life” is pure fabrication and sensationalistic. If anything at all, the dog was simply “messaged” to stay away for intruding or even chasing the coyote. That’s it.

I’ve been photo-documenting urban coyote behaviors, including their interactions with humans and pets, in urban parks for eight years.  I have only seen coyotes chase dogs in the manner shown in the news video clip, when a dog has gone chasing after the coyote first, or when the dog has intruded on the coyote in some way and then decided to run off. Dogs are constantly intruding on coyotes. A coyote’s nipping message is their attempt to drive the dog away, not maul him to death. It’s how they protect their territories or dens and it’s how they drive intruder coyotes away.

This series of 17 slides shows what happens when coyotes and larger dogs engage. When a coyote approaches a dog, it does so by making quick, short charges and quick retreats, where it is always ready to run off if the dog faces it. Coyotes aren’t animals who will take chances of being injured, so they avoid all-out fights with dogs. Please remember that running away by any animal raises a coyote’s adrenaline and incites a coyote to chase. We advise people never to run from a coyote for this reason. For more information on dog encounters, see video presentation, “Coyotes As Neighbors” and posting of March 30th: Pupping Season: What Behaviors to Expect If You Have A Dog, and What You Can Do,.

This slideshow requires JavaScript.

“Messaging” by coyotes consists of nips to the dog’s hindquarters and rarely amount to more than abrasions or scratches. You need to watch this behavior as it happens to really know what is going on. The coyote does not open its jaws for a big massive and incapacitating chomp into your dog. The coyote’s jaws remain fairly closed with only it’s lips pulled back a little from its front teeth so that it can pinch the dog enough to give it a firm message, and these are delivered to the back legs or rump of the dog.

How to prevent it in the future? Don’t let your pet wander freely in coyote areas, even if it’s your own wooded backyard. Coyotes want to be left alone, so keep your dog away from them. Since small pets can be mistaken for prey, please never leave your small pet outside unattended. Note that your fenced yard is a human fabrication which is supposed to keep other humans out. It won’t keep out raccoons, skunks, birds, gophers or coyotes. Coyotes have boundary markers which consist of fecal marking material, not physical fence barriers. So the only way to protect your pets, even in your own yard, is to supervise them or keep them leashed.


A Young Male Coyote Shows His “Mettle”

When a group of unleashed dogs with their walkers spotted a family of coyotes relaxing at the bottom of a hill, the unleashed dogs went after them. These are the only dogs in this particular park that regularly pursue and search out coyotes, even when coyotes are not out in the open or within sight. The coyotes inevitably flee the harassers: thirty-pound coyotes aren’t much of a match for 60 pound Labradors. I can imagine that the coyotes tire of the intrusions and onslaughts.

In spite of the tremendous screaming by the walkers, the dogs would not return to their owners until the owners physically went to retrieve them. One dog in particular was hell-bent on pursuing the coyotes — he’s the usual perpetrator of these raids and the leader of the rest of the dogs in that walking group.

Today the male coyote youngster gave standing-up-for-himself a try. Dad was there as support, but it was the youngster who put himself out on the front line, heading the defense, while Dad sort of backed him up from further back and often from behind the safety of a small bush. Dad and the youngster coyote stood their ground defending themselves and their turf, and even, as a warning tactic, went on the offensive, darting in to message the dog to leave. When the dog found himself unexpectedly surrounded on both sides by coyotes, his movements became indecisive and he became at a loss about what to do.  That is when the dog’s owner finally reached him, shooing away the coyotes and retrieving her dog.

My hope is that the dog felt uneasy enough in the situation he found himself in so that he’ll have second thoughts next time about intruding on coyotes. Let’s see.

Of course, if the owners had leashed their dogs — which they’ve often been admonished to do — the incident would not have happened. But these owners have no intention of leashing: “I never have and I’m not about to begin now”. This arrogance and amazing feeling of entitlement may not end up happily for everyone.

What is interesting, as far as I have observed, is that younger coyotes often appear to be more willing to stand up to an intruding antagonistic dog than the oldsters.
