Hi Grif - thanks for your reply!
His appetite is not quite as it was before the parasite treatments began a few weeks ago. I attributed it to the medication. I never asked the vet if the Panacur would affect his appetite.
As far as the shedding, it could be the medication, or a growth spurt, maybe a bit of both. Just never seen one shed that much lol
By the way, I have to collect another stool sample any time after Oct 5th and have it re-checked to see if the treatments have eradicated the parasites. Hopefully, he'll get a clean bill of health!
