These fear tactics are BS perpetrated by drug companies and vets.
There is no such thing as a heartworm preventative. There are chemicals that kills larvae, and there are different chemicals that kill adult worms. The science behind the heartworm disease is very clear, and the once-a-month regimen does nothing but overmedicate your dog with insecticides.
A dog cannot get bitten by a heartworm-carrying mosquito if the temperature outside does not remain 57 degrees or higher for 45 STRAIGHT days. That is impossible for most of the year in 47 out of 50 U.S. states.
