Double Defense Heartworm Protocol is an approach that protects dogs from mosquitoes and heartworms.1,2 This standard of care means that every dog should be on a macrocyclic lactone year-round and a mosquito repellent.

Groundbreaking studies by a third-party investigator, John McCall, MS, PhD, supports Double Defense in the fight against heartworms.

Phase one of the study proved that repelling and killing mosquitoes is effective in prohibiting microfilariae transmission from dogs to mosquitoes.2

Phase two of the study proved that dogs protected with Double Defense had no adult heartworms even using the JYD-34 strain of Dirofilaria immitis (one of the most resistant strains known).1

In the studies using the Double Defense approach, there were:

  • Fewer mosquito bites2
  • Fewer infected dogs2
  • No adult heartworms in dogs1

You can give dogs comprehensive heartworm protection with Double Defense.
