A new dog gets infected by a mosquito bite.
Adult worms live and reproduce in the heart and blood vessels of the lungs. It takes 6 months to test positive for heartworms after the offending mosquito bite.
If untreated, a heartworm infected dog can progress to severe disease, or even death, and can infect even more mosquitoes.
Infected mosquitoes become a threat for any unprotected dog.
Climate changes, family relocation and vacation travel have allowed heartworm-carrying mosquitos to expand their range3. Tri-Heart® Plus is easy to administer year-round to make sure your dog is always protected.
