Do you ever wonder if your smaller dog realises the bigger one could eat them as a snack if they so wished?
My dogs get on great, for the most part. The bigger dog has never shown any type of aggression toward anything. He's great at communicating his intentions (play bow/lowering his belly to the ground/tail wagging etc)
My smaller dog can be feisty at times. She loves playing with the bigger dog but if he accidentally hurts her or gets too close to her food she attacks him. A full-on, attempting-to-rip-his-throat-out attack, usually aimed at his ankles since she cannot actually reach his throat. He never appears to notice and simply carries on the game for the most part or just stands still and waits for her to calm down.
But it makes me wonder does she just have 100% faith that he would never, ever retaliate or does she not realise that she is smaller than some of his snacks or is she ever so slightly suicidal?
