“I have been giving my dogs Heartgard since they were old enough to take them. Never a problem or adverse reaction. I highly recommend this product for the peace of mind for you and your precious animals.”
“My Great Dane is 9 1/2 years old, and has been on Heartgard Plus his entire life. I live in the southeast where heartworm is possible year round. I also used Heartgard Plus with my previous Dane. I highly recommend it and wouldn't hesitate to use it with future dogs.”
