So a few months ago I took my 8yr old Chibi into the vet because he seemed to be a little off balance. We would be walking and he would kind of fall over if he stepped wrong or lifted his leg to pee and then would get off balance. They told me to start glucosamine/chondroitin and it might just be muscle weakness due to old age. So I did and for a while he seemed better. This last week though he seems worse again. The other night he tried to jump up on the couch and totally missed and fell on the floor on his side. He seemed OK but it was scary to see. Then last night he was trying to hop up on the stairs to get up into bed and he totally missed, hitting himself in the chest and falling on the floor. Neither time did he cry or yelp, he just kind of looked sad and forlorn. Should I take him back to the same vet that said this was no big deal or see a different one or is this just something that happens in old age? He otherwise seems normal.
