Answering Your Questions about 

Heartworm Disease

At Kindred Care Pet Hospital, we know you want the best for your pets and don’t want them to suffer from heartworm disease. The good news is, we’re here to ensure your dog, cat, or even ferret ever has to.


How Are Pets Infected with Heartworms?

Mosquitos are the main culprit. An adult female produces microscopic baby heartworms (microfilaria) that circulate in the bloodstream of its infected host animal. When another mosquito bites that host, it ingests baby worms, which develop into “infective stage” larvae in a 10-14-day period. When that infected mosquito bites another car, dog, or wild animal, the infective larvae enter their new host.

It takes around six months for a larva to sexually mature. After reaching maturity, a heartworm can live up to seven years in dogs and three years in cats.

How Can I Tell if My Pet Has Heartworm Disease?

In the disease’s early stages, dogs show little or no signs of symptoms. As the infection persists, more signs of ill-health often develop.

Cats can have either subtle or very dramatic signs of the disease. Sometimes a cat will have difficulty walking, experience seizures or fainting, or suffer from abdominal fluid accumulation. Too often, the first sign in cats is sudden collapse or death.

When Should My Pet Be Tested?

All dogs should be tested on an annual basis for heartworm infection. Here are some guidelines for testing:

  • All puppies under seven months of age should be started on heartworm prevention. Your puppy should be tested six months after your initial visit and annually from there on.
  • An adult dog over the age of seven months but not previously on a preventive should be tested before starting heartworm prevention.
  • Annual testing is a must, to ensure your dog’s heart prevention program is working.

It is harder to detect heartworm disease in cats because they are much less likely to have adult heartworms. Your veterinarian uses both an antigen and an antibody test to screen cat for exposure to heartworm infection.  Since there is no approved treatment for heartworms in cats, prevention is essential.

What if My Pet Tests Positive for Heartworms?

After your veterinarian determines your pet is determined to be stable, he will follow guidelines developed by The American Heartworm Society for a plan of action.

 The implications of the COVID-19 are concerning to all. Our top priority is to protect the health and well-being of our staff, clients and community members. Having said that, we will be taking some precautionary measures and actions to prevent the spread of COVID-19 in accordance with the CDC recommendations; wEARING OF MASK, Hand washing and social distancing guidelines have been implemented. Team members who are not feeling well or have potential exposure to COVID-19 are being asked to stay at home. We have implemented an increased scope and frequency of cleaning in our facility. Surfaces that are touched frequently are being cleaned often and wiped down. Hand sanitizers are placed in multiple locations. We are encouraging drop off appointments, while spacing out the appointments that absolutely cannot be dropped off in hope of limiting face to face time while ensuring that our patients are getting all of the care needed. We encourage quick hand-off of your pets to clinic staff. In some situations, a case by case analysis of the situation may be considered as far as coming in to the hospital.  We want to thank all our dear clients for your understanding and cooperation in these challenging times.  This too shall pass. 

 Thanks, Dr. Fidelis & Staff.
