Hi Weimlove,
I don’t have a huge Heartworm threat up here but, to be on the safe side I did some reading up on it & non toxics approaches. Dr. Wil Falconer, a holistic DVM, wrote a book on natural Heartworm prevention. His website is here: http://vitalanimal.com/immune-path/.
Another sight that might be helpful is this one, it gives 6 homeopathic methods and it encourages the same kind of program that Shawna mentioned. http://www.danebytes.com/heartworm-cures.htm
The bottom line is a healthy animal defends its self against Heartworm, and other parasitic attacks. Meds are insecticides… Poisons. If you use Heartworm “Meds”, you are also making your pet sick. Parasites are stronger than mammals. They’re harder to kill. In order to kill, or poison the parasite the dose of poison has to be pretty high. Keeping your pet optimally healthy, and using non-toxic repellents on your pet for the insect vector (Mosquitos) is a much better foundation. Like Shawna, I strongly believe that garlic can kill the wolbachia. But check out some of the homeopathic site’s cures. 😉
