This last behavior in the series on vying for Dad’s affection or for possessing him, I thought was particularly interesting. This series of behaviors occurred one right after the other, each behavior increasing with intensity the desire to grab Dad’s attention and affection away from the other sibling. See the last posting on Paws On Pop.
The female youngster has learned from the other members of the family, including her mother, father and brothers — through their intense interest in her odors — that she has or “is” something special, something “different” from the rest of them.
Here, she’s offering herself to be smelled by her Dad — an activity that will draw him to her — and therefore away from her sibling rival who is not depicted in the photos but who is present a few feet away, and who clearly also desires Dad’s love and attention.
She walks up to Dad and lies down and begins to roll over on her back. Dad seems to ignore her the first time — see the first slide. But she tries again, getting up and walking to right in front of him, lying down again and rolling on her back, exposing her underside. This time she has grabbed his attention.
Dad indeed sniffs her and then she gets up. They both begin to walk away, but not before Dad confirms his dominance, or possibly his affection, or maybe both, by enclosing her snout in his.
