Hi Everyone,

My vet gave us three days worth of Panacur, a dewormer, for our 11 week old puppy, Indy. He started it yesterday at breakfast and had no issues until it was time for bed. He was up ALL night bouncing off the walls. I'm not sure it had anything to do with the meds, but he should have been exhausted based on the day's activities. Today, about 12 hours after his second dose, he had horrible diarrhea- once on the sidewalk before we could even get to the grass. He has gone 4 times in the past hour and a half. I did not see any worms in his stool. Again, he is usually in bed at 1 a.m., but despite the illness, he is very hyper and I can't seem to wear him out in between bathroom time. 

I tried to look up these side effects online, but I'm just seeing vomiting as a side effect. Has anyone had this happen with Panacur and young puppies? I'm worried about him.
