Ellie Mae, one of our Newfoundland dogs, has been experiencing a mysterious problem with one of her front legs. Twice in the last couple weeks, inexplicably, she’s started limping. Within a day or two, the limp has disappeared. Our vet examined her this morning, but was unable to locate any specific problem beyond some arthritis in her joints, which we knew about. They’re running a test to see if she has Lyme Disease as that can cause lameness. If the problem persists, once we’ve ruled out Lyme, may be X-rays to try to get a picture of the problem. We would like to isolate specifically where the issue is before doing X-rays though because right now it isn’t clear. If it happens again, we’ll shoot some video of her limping when it is most pronounced to show the vet. The last episode happened yesterday evening. She was still limping quite a bit this morning but by the time we left the vet’s she was walking just about normally.
