*Heartgard Plus Chewables may cause sensitivities in herding dog breeds. Use with caution, as Collies and other herding dog breeds have been known to have adverse reactions to ivermectin administered at elevated dose levels.

*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.

*Heartgard Plus Chewables are for dogs only. Do not give to cats.

*Do not give Heartgard Plus Chewables to your pet if he or she is already taking another heartworm medication.
