Just keep using Ivomec.

Before the big Ivomec craze I knew a Vet that trapped and he gave ever coyote he caught a shot of it. He said it was a 100% cure for any parasites, including mange. I asked him then about giving it to a dog and he said it was the way to go and it's hard to overdose them.

People tend to think all heartworm infections are the same. There are many different classes of heartworms. You can even have heartworms and have a negative test. The test only comes back positive if you have adult females. An all male infection will produce a negative test. People compare heartworm treatments but you have to compare stage of disease. If your dog was on heartworm prevention and came up positive its likely had 1or 2 worms. In these cases ivermectin can often times kill the worms at higher doses. Ivermectin can also be toxic to dogs at high doses. The problem is ivermectin has been used so extensively over the last 30 years concerns are arising that there may be resistance like bacteria to antibiotics. Glad your dog was one of the lucky ones. A lot aren't so lucky.

My lab (RIP ) tested positive for them once, eventhough he had been on prevention his whole life. The vet said some shite about it being a national problem with that brand of meds, like a bad batch or something. Same thing though, they put him on something that eventually rid him of it.
