How do Heartgard Plus Chewables work?
Heartgard Plus Chewables contain ivermectin, a broad-spectrum antiparasitic medication used to prevent heartworms. They also contain Pyrantel Pamoate, an anthelminthic, used to prevent roundworms and hookworms.
Studies have indicated that certain dogs of the herding breeds are more sensitive to the effects of ivermectin administered at elevated dose levels due to the MDR1 gene. Dog breeds that may be affected include Australian Shepherd, Australian Shepherd Mini, Border Collie, Collie and English Shepherd.
Heartgard Plus Chewables may cause sensitivities in herding dog breeds. Heartgard Plus Chewables should be chewed, not swallowed whole. The chewables may be broken into pieces and fed to dogs that normally swallow treats whole. Make sure that your dog eats the entire dose. It is important to give your dog Heartgard Plus Chewables every month, year round. Do not skip winter months, as your dog may become infected if left unprotected. If you miss more than two months of dosage, please consult with your veterinarian as to whether to continue medication.

What is the most important thing I should know about Heartgard Plus Chewables?
The active ingredients in Heartgard Plus Chewables are ivermectin and pyrantel pamoate. Use with caution, as Collies and other herding dog breeds have been known to have adverse reactions to ivermectin administered at elevated dose levels. Heartworm testing should be performed prior to the start of prevention therapy. If your pet is off Heartgard Plus Chewables for 6 months or less, start the medication and test after 6 months since microfilaria, that take 6 months to mature, will result in a positive test result. In addition, Heartgard Plus Chewables have shown a wide margin of safety at the recommended dose level in dogs including pregnant or breeding dogs, stud dogs and puppies aged 6 or more weeks.
