About This Item
For use in animals only. Your furry friend must have a current heartworm test result on file with your veterinarian in order to be prescribed heartworm medication. Please visit your veterinarian to have this test performed annually to protect your four-legged friend. Iverhart Plus Chewable Tablets are prescribed to help protect your pet from heartworm disease, which can cause tiredness, decreased appetite and, eventually, heart failure in dogs. These easy-to-feed tablets may also help control two common intestinal parasites, roundworms and hookworms. Iverhart Plus chewables help provide safe and effective protection each month, and come in a pork liver-flavored chewable—so they're easy to give to your dog as a tasty treat.
Proudly sourced directly from the manufacturer or their approved distributor. Guaranteed genuine and backed by the manufacturer.

Ineligible for Virbac Rebate
My vet no longer carries Iverhart but I didn't know they do through their online pharmacy which is much cheaper than Chewy and would have been eligible for the Virbac rebate. Virbac does not honor Chewy pharmacy for rebates so I ended up paying more.

I used my 20% off coupon and got free shipping also. Order arrived in a timely fashion. Y'all are the best!
Good stuff!
That’s what I always say to the dogs when it is treat time and that’s how I gave it to them, as a treat. So far so good!!!
Yuck, is what my dog said!
I had a very hard time getting my dog to eat this. Not with the dog food, not with a treat, not with peanut butter, not with anything that I tried. She hates it and will not take it no matter how I try to hide it.
Iverhart plus
very happy with the product and the speedy delivery. I was disappointed that I did not get a discount on my first order since I did it over the phone. I will tell my friends how easy it was to use Chewy.
I love Chewy
Great service, great people to talk to, My dog doesn't like chewable and my vet recommended tablets and he also mentioned Chewy.
