I have given Huey heartworm meds since we got him. We live Iin Ga where mosquitoes are plentiful. Our vet also recommends annual testing even if he hasnt missed a dose, but I do have the option to decline the test if I know I havent missed a dose. We use Trifexis, which is a combination of Sentinal heartworm med plus comfortis flea med. He hasn't has any problems with this at all. |
