Took him to the vet on Saturday and they confirmed that he had a stroke. Lost the use of his back legs. I was prepared to put him down, but the Dr wanted to try Prednisone. Long story short, my boy recovered. Dr said dogs are a lot different than humans. Pretty crazy, but I'm glad he is acting more like himself. Pretty funny, but before he had the stroke, we thought he was going deaf and about blind, but now he seems to have gotten back a lot of his hearing! Still got cateracts... I'm glad he's still here. He's a good boy
Doubt it was a stroke, since prednisone worked. Good to keep him off of stairs or steps if you can and help him go up and down otherwise. A dog jumping up and down from furniture and going up and down stairs really wears out the spine.
