Heartgard up to 25 pounds
We buy this for our three Shih tzus. They all eat it although we usually break it into smaller pieces and give it to them. So far it’s working well.

Our dog loves his monthly medication.
The well-packaged order arrived a few days after we placed the order in perfect condition. Very good service.

Great product
It’s my 3rd year of buying these products for my 3 dogs. It’s save me a lot of money buying from them, you don’t need prescription from vets plus savings of not paying for annual test for heart-worm. Thank you.

We use Heartgard exclusively for all our dogs
We've been using Heartgard for more than 20 years with our dogs (cocker spaniels) and we have never had a problem. We live in Florida, and all kinds of bugs and pathogens are common. Never had a problem with anything being picked up by any of the animals and they are outdoors a lot. They love the taste, take the chews readily, and never have a problem with after effects.
