Hi! We have a dog that got hookworm from contaminated feces of another animal in our yard. We treated her with 2 doses of medication, however our vet instructed we give the 2nd dose after one week. Everything I've read says 2-4 weeks for the 2nd dose, considering the life cycle of the larvae into adults. Our dog got them again. Would you recommend giving the 2nd dose after one week, or two weeks?
