Flea and Heartworm Preventatives 

Heartworm Protection

Heartworm disease may be transmitted to your dog when they are bitten by an infected mosquito. Due to our warm climate in Florida, mosquito’s are active all year long. Dogs must receive a heartworm protection medication every 30 days to protect them from contracting heartworms.

Heartworm preventatives are not meant to cure a dog who is heartworm infected. Putting them on a preventative while they are heartworm positive may make them seriously ill. Heartworm protection medications require a veterinarian to prescribe.

Peggy Adams Animal Rescue League is happy to provide you with heartworm and flea preventatives at affordable prices. In order to purchase the following preventatives from the League, pets must be a patient of Peggy Adams Animal Rescue League's Wellness/Vaccine Clinic and/or Surgical Clinic. If you are not, please bring your pet to our Vaccine Clinic for a wellness check and/or vaccinations.
