As for Charlie, yes, them feeling better is a situation of it's own.
The fencing is an important thing to get done, and I hope that you can get that done sooner than later.
If he can't hold his urine as he did before, maybe that could change with a dose change? The vets can only estimate how any given medicine will work with any given animal. A lot of times the dose must be tweaked a bit to personalize it to the dog in question.
There may be a 'sweet spot' with this medication where it will still work, but reduce side effects a little. I suppose you could call, explain, and ask them. Nothing to lose there.
I always have Charlie's situation on my mind for both of you.
Good luck as you both adjust to these changes.
Did you wrap silverware today? If so, how did it go?
