1 oz per gallon of water sole source of water for one day.The vet confirmed round worms, but then didn't tell me what to use or what dosage because she was in a surgery. So I did buy wazine but im not sure on the dosage orally and a few posts on here claim that all the worms being expelled at once will block up the intestines and I don't want to do that to a broody who isn't pooping a lot anyway
