I'm in MD, like you, and I used to not give Jackson flea/tick and heartworm meds in the winter but this winter, he got 3 ticks in 3 months! I thought those suckers were gone by now but apparently not. My vet said to keep him on year round on both Frontline and Heartguard, so now I am going to. He already tested positive once for Lymes last year and luckily, a few weeks ago, he tested negative for everything so I wanna keep it that way. |
