My dog is predisposed to have reactions to ingredients in every heartworm medication. I have received no definitive answer from my vet as to what to do except to basically play Russian Roulette which I’m not really willing to do. I would like to know if you have any advice on how to herbally treat heartworm without using conventional treatment. He is a husky, German Shepherd, wolf mix he has been DNA tested and he is 20 months old. Any information that you could provide would be helpful. My name is James Dalton and if you need to contact me my number is 864-906-4305. Thank you
