Hi there. About 4 days ago, my puppy Max(now 3 mths old) started to have what looked like rice in his stool. They didn't move as well. I had him to the vet yesterday for his vac. I had told the vet and she said it wasn't serious, and the sentinal would clear it up. Now tonight he accidently went inside and when I was cleaning it up, I noticed now the worms are moving. Does anyone know if this is what is suppose to happen after treating them, would that be getting rid of them? He has also been gassy as well. Any replies greatly appreciated.
