Orange County Animal Services’ Heartworm Treatment Sponsorship Program

We do not want heartworms to be a barrier to adopting a shelter dog. To help increase adoptions and ease the costs associated with heartworm treatment, Orange County Animal Services, launched a program allowing local businesses to sponsor treatment for heartworm afflicted dogs. At any given time, 10% of dogs on average at OCAS have heartworms, and that is often a deterrent for adopters due to the price tag associated with the disease. As such, many dogs testing positive are sponsored entirely for their treatments.

It is the hope of OCAS that in removing the financial barriers, heartworm positive dogs will be adopted based on their personalities, rather than turned away due to financial hurdles.

What is Heartworm Disease?

Heartworm is a parasitic roundworm that is spread from host to host through the bites of mosquitoes. When a dog is bitten by an infected mosquito, the transmitted larvae mature into adult heartworms. They then begin reproducing in the heart, lungs and surrounding blood vessels.

Heartworm disease can be fatal if left untreated, though it is a curable disease once contracted. It is also highly preventable. Orange County Animal Services recommends proactive care through heartworm preventative medication.

Common Misconceptions

  • People cannot get heartworms from their dogs. It’s a specific parasite that affects only dogs and occasionally cats.
  • Dogs cannot transmit heartworms to each other. Only a bite from an infected mosquito can transmit the disease.
  • Heartworm disease can be avoided by treating your dog with heartworm preventatives either topically, by pill or via injections.
  • A dog can get heartworm disease even after he or she has been successfully treated and cured. That’s why prevention is so crucial.

How Do I Become a Heartworm Treatment Sponsor?

In order to become a sponsor, please email A sponsor pledges $350 per dog, which is the cost of heartworm treatment. Many businesses choose to sponsor one animal per month, but any contributions are welcomed.

As a token of appreciation for their life-saving support, each sponsor’s logo will be displayed on OCAS’s website. They will also receive frequent recognition via social media. Not to mention, infinite gratitude from the shelter staff and animals alike.
