I have a dog what I think is part lab part dal. Mostly white with black spots under white coat. Anyway the last day or so he has started limping and I was thinking he was favoring his foot right foot pad this morning, but this evening he won’t let you touch anything from his hip down on both sides without trying to bite you. He is very careful when stepping and doesn’t want to jump up on anything or seem to step on anything not at the same level He has always had some issues like not liking water period to wash him the vet has to dope him
