Our ticks this year have not been as bad as some years but I found one embedded in my wrist near my fitbitoid thing-- I am sure it came from one of the dogs.. We don't treat for heartworm in the winter because of no mosquitoes and unless it is a mild winter we forego the nextguard as well but that is a risk of course and we have squirrels and chipmunks everywhere so fleas are always a possibility. Some years the ticks are really something but knock on wood not this year so far.
