I live in WI and had read about the life cycle of the Heart worm before. It definitely changed my mind on when I would give it to my dogs! Heart guard, ect.. is poison and has been linked to a number of problems so I want to give it as little as possible!! Here in WI I may only need to give it in July and August!!! I have never heard of a vet saying that you should give it in the winter!! [for those of us who have winter] |
