My dog started whimpering today every time he picked up his leg. He does seem to put all his weight on it either. He has no injury to his paws and was just had nails done 2 weeks ago. He is only 4 years old. He is an Irish wolf hound and black lab mix. He is an ex-large dog. Is there anything I can do. He really likes it when I massage his leg but will not let me lift it very high. What do I do?

Your dog can very well have a torn mussel or ligament. It would be a good idea to take your dog to the vet. Do you have a picture of your dog?
