“Heartgard has work well for our two dogs (as well as previous 2 dogs) for many years, we have had no side effects and the product has be effective at controlling heartworm as well as roundworms and hookworms. They run in the yard, woods and frequently walking in the neighborhood - noses stuck to the ground. Glad I can depend on the product. Allivet has excellent prices, communication and dependable service.”
