[My baby Milo]

My Milo went to the vet today for his last shots. He is really sore. He won't even let us pick him up. I tried but he barked out like it hurt him. He also got his leg checked. He has been holding it up. They told me it was his knee and that he needed surgery to fix it. They gave me some pain med. to make him feel better but i thought it would make him rest but he keeps walking around not playing but just can't be still. He want's on the couch but he won't let us pick him up. Has anyone ever had their baby do this after his shots? I think he is more sore from the shots than his knee because he has been playing this morning before his appt. I am going for an second opinion about his knee to.
