Question about urinary incontinence and e-cuniculi..

Ok a while ago Pringle was wet a lot and we put it down to e.cuniculi, he had about 7weeks of panacur and has been dry, but ocasionally he gets a wee bit wet on bottom of his tail, last night and this morning he was a bit wetter than he has been, im really concerned . Is it normal for them to still get a bit wet or shouldnt this happen?
Hes at the vet on Monday for a check up as he got his teeth done 4weeks ago and its just to make sure everything is ok with all his problems.

Any advice would be greatfully appreciated.
Thanks.

Unfortunately eliminating the e.c. doesn't undo damage already done so there may be ongoing problems.
It may be worth have blood tests to check his kidney function as well and consider an xray to check for calcification.

also you need to keep retreating as you will never completely eliminate. Sooty needs about 9 days every three months to keep it at bay.

I do panacur them all every 3months, but i just stopped Pringles about 4/5weeks ago. Pringle got blood tests near the end of his treatment for panacur and everything came back fine, their was no damage.
