Hannah's deworming at the breeders didn't take care of the worms which our vet set she was born with or got soon after birth. We found out from a fecal test at her first visit to our vet when she was 10 weeks old that she still had roundworms. She had two doses of the medicine two weeks apart. The worms all came out a day after the first dose. Ewwww!
It was definitely science fiction looking poop!!! Maxwell had to have the medicine too, but no worms came out in his poop. We didn't have to do anything else and everyone was fine.
Good luck. Seeing those worms is definitely freaky. I was completely grossed out!!
