Hey guys, new here. Looking for any advice on treating heartworm. My dog was infected last spring(just found out at his annual checkup) when I missed a treatment. Started on doxy to prepare for injections but now my car is broken down and I am down to $170 to my name. I live in the bush way up in northern ontario. He got infected down south. I have read about people treating with preventative if the case is mild. Do you think having it for a year is early enough to try this method? Hes shown no signs and is incredibly active(just got back to cabin from 3 weeks canoeing). Thanks for any advice.
