I have my dogs on Interceptor. I have never heard of the things you mention. Is it prescription from the vet, over the counter, or what. I don't know where you live, but here on the Texas coast i would not dream of using anything that was not proven to work.. It is known that any heartworm preventative can fail, tho rarely. I would always take one with a 1% failure rate than one with a 20% failure rate, or worse. But as I said, I know nothing about the things you named. There may be somewhere here who has heard of them and can answer better than i can.
