Just found an old Heartgard box from September 2009, can it still be used safely for my year-old Collie?

I just stumbled upon an old box of Heartgard from way back in September 2009 while cleaning out a cabinet. My Collie is only a year old, and I’m wondering if it would be safe to use it now or if I should get a new one. Does Heartgard expire, or could this still effectively protect my dog from heartworms?

Answer

It's important to use heartworm prevention medications that are not expired, as they may not be effective in protecting your dog. The Heartgard from 2009 is expired and should not be used for your Collie.

  • Do not use expired Heartgard on your dog.
  • Expired medications may lose effectiveness over time.
  • Get a new and current product to ensure your dog's safety.

Veterinary medications, including Heartgard, have expiration dates for a reason. Using expired products on your dog can mean they won’t work properly, leaving your pet unprotected against heartworm disease. Since your found Heartgard is from 2009, it’s too old to use safely. I recommend purchasing a new supply from your veterinarian or a trusted pharmacy.
