yes, it could be something else for sure....He has a large tumor on his chest that can't be operated on because he is too old and had a bad time with anesthesia the last time he had his teeth worked on, now his teeth are pretty bad (well,he is over 16 and a small dog), and has this tumor which has never been painful to him. He has slowed down a ton in the past year which is fine, I carry him if needed, and he just moves slow. but he eats great and gets all excited even jumping up when we come home still etc. He is totally deaf now and has much lower vision.
The fall was all my fault. I left the basement door open when I brought laundry up, usually I close it. the lights were off and I think he just lost his way. He does choose to go down there sometimes so may have started out that way but obviously didn't make it. The rolling thing was the craziest thing I've ever seen.
He has been awake now and I let him up and he walked just as before the fall. Last night he tried but kept falling. Now he ate and is resting by me as normal again. Gosh, I hope he is ok for a few months at least. I'd just really not like to tell Q his puppy died during the holidays/birthday season. (Q will be 16 in Jan!)
Both dogs are cuddling now. I am going to really watch him closely. Probably going to take him to the vet to check him out anyway.
