My point exactly , that is what I was referring to when I said, I go to Buena Vista to buy my groceries ( which is only 7900 ft .) Most people, take their dogs to many different places and if they are not on heartworm preventive they could be infected . I don't keep my dogs on heartworm preventive in the winter, but if I was going to send one away from Colorado I would put them on it asap.
