Yesterday Luke had a very active day. He also decided it would be fun to start jumping like crazy! He took two flying leaps down 3 stone steps, landing in a brick patio! He didn't fall when he landed, just took off running. (I put a stop to the jumping... mean mommy!) But now he's acting like he has an itch on his side/back that he can't reach. I've checked for bugs etc. Couldn't find a thing. I thought maybe itchy skin in one spot and put some aloe spray I have for dogs on it. Didn't help. He walks a bit then turns to bite/scratch his side, but can't reach. I scratch it and he tries to bite my hand. It's only one side, one area. Late today he started licking his front leg on the same side. Now I wonder if he could have hurt himself. He's not limping or anything. He has no problem laying on that side. Would a pinched nerve or pulled back muscle make him feel like itching?
