Prevention matters: Monthly prevention is usually far cheaper than treating established heartworm disease. Dogs with symptoms need veterinary evaluation before treatment planning.

Confirming and staging$150 - $600Confirmatory test, blood work, x-rays, and exam

What To Ask Before Starting

  • Which protocol is being used and how many visits are included?
  • Are x-rays, blood work, and follow-up testing included?
  • What symptoms mean the dog needs emergency care during treatment?
  • How strict should exercise restriction be and for how long?

Why Size Matters

Medication dosage is weight-based. Large dogs often cost more because they need higher medication quantities and may carry more treatment risk.
