I have a VERY old Sprollie (Freddie) who is between 17 and 19. I got him in 1997 when I was told he was a year old (he was certainly adult), when I took him to the vet, the vet thought he was about 3 or 4, so he's somewhere in quite a wide band.
He had some arthritis problems, which were managed by metacam but I've taken him off the metacam as, in the summer he has been fine without it.
The real problem is my house has a large kitchen dinner with tiled floors, a few times I've come home from work and found him with his legs splated where he's been unable to get up. He doesn't have the muscle strength to not splay. I've put loads of rugs down, but he keeps going "off piste" and splaying out. on 2 occasions he'd wet himself.
In fairness, in total over the last year he's had 4 loss of control incidents. Two where he's been really deeply asleep and just wee'd and 2 when he's got stuck on the floor, and that makes me think he's in distress on the floor.
Other than rugs, any ideas? I don't think I am at "quality of life" issues yet, because the arthritis is so much better and he's not in pain.
