I recall the same, the antibodies. Still I know the vet has retested the dog, a few months back and sold some more antibiotics for him. Then again a couple of days ago when we needed to have a lump on the dog's side (dog in avatar) side, not a cancer, it seems, just a lump of fat and we're to keep a "eye" on it. Wonder if the vet has a "good thing going" with these lymn tests :zip:
