I'm near Cleveland, Ohio - Jack had been on Interceptor and one of the topical flea preventatives. With the manufacturing shortages of Interceptor, I put Jack on Trifexis - this covers not only heartworms, but other parasites and fleas as well. He has had no reactions whatsoever. I do stop giving it to him either late November or December through about April - though this year I started him back on his regimen in March as we were headed to Florida for vacation and I wanted to make certain he was protected. My vet recommends giving him meds year round to but Jack does not stay outside very long during the cold winter months - surely not long enough to contract anything.
