I’m cat sitting two cats for a neighbor and I’ve been bringing Dog with me. Dog thinks all cats are her friend. The cats don’t know about this.
Today. One of the cats let me pet on him and even let Dog sniff him, so progress!
Just have the coax the other one out.
Dog is good though. She doesn’t chase cats, doesn’t react to being pawed, and lays down the moment a cat gets nervous, using her long legs as a way to get closer instead of her face.
