We had an Old English on Metacam for over a year, no problems with incontinence, but once pain was under control we reduced dose to just enough to keep her moving easily.
She was also on some chews with Glucosamine, a teaspoon of codliver oil on her feed.
Is he on a high dose? I wonder if too much could be deadening any 'feeling the need to go'?
I wonder if the vet could advise on something for incontinence?
We had got a younger dog and she would still bounce round the yard with him, but then went downhill quite fast (she was getting on a bit by then)
One evening walk she just looked at me as though she was saying she'd had enough, she looked so miserable, tired and sad, next day it was done. Up till then she's had a brightness in her eyes.
But should I have had to leave it to her to tell me? should I have let her go before she looked so down?
I used have a Rough Collie, who I couldn't bear to part with, I'd sometimes have to help her stand up, once up she seemed OK, then she started wetting her bed, and LOOKED embarrased, she knew. I always regret leaving it too long.
Only we can decide, and its so hard.
I'd have a word with the vet, Good luck
