This handsome red pit bull terrier dog is being fostered before rehoming. He appears to be having difficulty in find new owners. The foster carer has a cat it seems to me. The dog appears to be frightened of the cat. When the cat is sleeping the dog gingerly tiptoes around her/him to avoid waking up the cat. It looks amusing and slightly odd. The behavior is very human. Perhaps the dog is simply respecting the cat but it looks more like fear to me. There are many videos like this of dogs showing fear of the cats with whom they live. In these homes, the cat is the boss.
It seems remarkable that such a strong and capable dog can be scared of a domestic cat. It must depend on the personality of the dog and the cat. Perhaps this dog is a little timid and the cat might have a strong, confident character.
Dog lovers might be displeased to see the video – to see such a strong animal cowed by a measly cat! It will amuse cat lovers I suspect. Personally, I find the dog’s actions fascinating. The way he behaves like a person and at the end he has one paw off the ground as he looks in a very concerned way at the place (out of frame) where the cat is sleeping.
