I don't think anybody on Pet Talk would intentionally put their dogs in danger. Some areas don't need hearworm preventative.

I don't give it for another reason. I have researched this and am very comfortable with my decision. And believe me, I didn't take it lightly, since I live in Florida and have had a heartworm positive dog before and have worked at a vet and witnessed plenty of treatments.
