Not in my experience. I've seen dogs do it to other dogs and then (literally) shake it off. But I've also seen it go the other way and turn into an all-out attack a split second later. Those are the cases where the newly adopted dog ends up killing the family cat.I have a question, regarding the staring.....does it always signify potential aggression?
Interesting. I did always think it was related to prey drive for him. Oddly, he's always been great with my parents cats and doesn't even show any interest in small animals (a bunny running through the yard literally ran into him yesterday).When I test a dog with cats I especially look for this reaction. AT that time, it's a prey drive thing but in my experience, these are the dogs most likely to be unable to live with cats. I did foster one doberman who was able to adapt and live peacefully with a resident cat but most often my recommendation is no cats and possibly no small animals at all.
If I were to see a dog eyeballing me with this stance, I would definitely look for a safe exit as quickly as possible.
