Our 3 yr. old black lab was sick last night and was very subdued this morning, so DH took him to the vet. They thought he'd eaten something, so said no food for 24 hrs. etc. He was also holding his back leg up, but the vet manipulated it and could find nothing wrong.
He now seems to be in more pain and is looking really sad for himself. We are taking him back to the vet tonight, but just wondered if anyone had any ideas of what we should ask?
