Hi I have to patterdale pups 3 month old. The problem is when I walk them one of them is having major problems with his paws they drive him mad about 10 minutes aftet we return. He runs around the house yelping scratching his paws on everything he can this can go on all night. The other one is fine. Does amyone know what this maybe or should I just take him to vet this has been going on everytime I go out for a week
