Product Detail: Heartgard Plus

Heartgard Plus eliminates the tissue stages of heartworm larvae (Dirofilaria immitis) and removes adult roundworms (Toxocara canis, Toxascaris leonina) and hookworms (Ancylostoma caninum, A. braziliense, Uncinaria stenocephala) from dogs. Heartgard will control heartworm infections acquired in the previous 4 months provided that monthly treatment is continued for at least 12 consecutive months.

The chewable beef cube is highly palatable and most dogs will accept Heartgard Plus as a treat.

This product has kept my two kids worry free from heart worms. One of my dogs has epilepsy so he can't afford any diseases. My other dog is going to be 11 years tomorrow. They have both been on the Heartgard and have never gotten heart worms. I highly recommend it and have told my friends about it.

Heartgard Plus has done an excellent job of keeping my dogs healthy for years. They think they are getting a treat each month and I have never had any product failure from Heartgard. Wouldn't think of changing.

My dog loves taking this medicine -- all I have to do is toss it up in the air and she catches it and wolfs it down! Comes in convenient packaging with stickers to remind you when the next dose is due.

Great Product

My dog loves this product. He takes it no problem once a month, he thinks it's a treat, no need to wrap it in cheese or lunch meat like some other heartworm preventatives I've used in the past. And it does actually prevent heart worm and the other intestinal worms. We live in Texas and have millions of mosquitos all year round and he tests negative every time, which is amazing because when he was adopted from the pound he was hearty worm heavy. Great product. Definately recommend.
