Hello. My dog recently had puppies. I brought them to the vets last Friday. They only tested one of the puppies for worms, which came back clean. But yesterday I saw them in one of the puppies stool. They were all treated for worms at 4 weeks , but the vet didn't give me the nemex 2 at last vet visit. I'm putting them all on sentinel spectrum tomorrow when the meds arrive in mail.So my question is, do i buy and treat them with the nemex 2 today, or wait for the SSpectrum tomorrow which is for worms also. Dont wanna hurt my little babies by giving them too many meds .Sorry for such a long post. Any info would be greatly appreciated!!
