I am sorry about the fall on the ice. It is unbearable to see them do that. I am also curious as to any other advice you get.
We have done the ramp, so no steps, recently getting the harness to assist with standing for any ( small ) length of time vs her back legs sinking as she stands or getting up from a down position if needed.
But you mentioned him favoring one leg when standing. Is that something to look into? Do his toes go under when walking? Dragging either leg?
My hope is that all ice is away soon eliminating the problem of falls and slips on that difficult surface!!!
She does eat most meals laying down. Sometimes eating from the raised bowl, but she does seem more comfortable laying down.
I could be wrong, but Shana does not exhibit that she is in any pain so no pain meds here. Awhile ago we tried Rymidal and Gabapentin to no difference. She was difficult to get her pills into so I stopped.
Keep us posted of any answers you find !!!
