I wanted to post some videos of Colby walking. This is what we have been dealing with. Have any of you seen this before. I have watched some videos on what the vet thinks (cerebellar hypoplasia) and I do not know what to think. He kind of resembles some of the dogs in the other videos, but I do not understand how he was exactly the same way when we got him and then came so far just to regress all the way back to how he used to be again. My heart is breaking for him, but he is my special boy.
