Why might my older dog be stumbling?
I have an 11 year old Yorkie and I have noticed her stumbling and having trouble getting her feet under her in time to move like she wants to. Recently I had her at the vet to inquire about her having difficulty jumping on the couch. She was diagnosed as having back pain and I was given a medication to give her as needed. It is a pain pill but I can't recall the name. I don't give her the does daily but skip one or two days (usually). Could it be the medicine? Could the dose be too high? Do you think it is something else?
