I switched from Sentinel to Interceptor which is JUST the heartworm not the flea. I also asked the vet about how dangerous it was and she said they would have to take a HUGE dose for it to be harmful. However, we took them off the flea one because they only go outside to potty they don't run through the forest or anything and they get weekly baths with lavender Buddy Wash that deters fleas. My vet was fine with it. I would just ask your vet if the flea part is necessary. I know dogs can die from heartworm so we do keep them on that. I don't know of any natural heartworm meds - does anyone? |
