More about Heartworm Testing & Prevention
What this service does and why it matters
Heartworm disease is spread by mosquitoes and can cause serious damage to a dog's heart, lungs, and blood vessels. Testing helps confirm whether prevention can be started or safely continued.
- For pets, prevention is far easier on the body than heartworm treatment after infection.
- For owners, routine testing and prevention reduce the risk of a difficult, expensive disease process.
- For the community, prevention helps interrupt the cycle of mosquito-spread disease among unprotected dogs.
What to know before a visit
- Dogs need a current heartworm test before starting or refilling heartworm prevention.
- Heartworm preventatives do not kill adult heartworms.
- Year-round prevention is recommended because mosquitoes can appear outside the expected season.
- Indoor cats can also be exposed to mosquitoes, but PETS Clinic heartworm testing language on this site is focused on dog service availability.
