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.

Small so easy to hide in cheese
I was weary when I first got a phx for this new heartgard type medication, because well I had used heartguard for so many years. But this new medication is supposed to do more, and is a small pill compared to the heartguard. I liked the fact that the heartguard was a chewy meaty snack for my dogs, but thought that maybe this wouldn't appeal to every dog and might make it harder for the owner to feed it to them. So it a small pill easy to hide in cheese. My only complaint is that I have a petite chihuahua (3lbs) and I have to break the pill into smaller pieces so that she can eat the smaller pieces. Sometimes the pill crushes rather than splits, resulting in pill dust. But overall I like this product and will probably use again.
Shipping ???
Too much for this product and packaging. It is far more than chewy is charged. Should not be a profit margin in shipping.
Great Pharmacy
Chewy's Pharmacy is great. They're nice to talk to & does whatever needed to assure you to have the product for your pet. I definitely recommend them for your Baby.
So far so good
Too soon to comment. It’s not time for the dog’s next dose yet.
Just received.
I have only given Fawn 1 tablet . my Vet highly recommended this product and i trust my Vet.
Same Great Protection
Iverhart Plus, provides the same protection that many other brands do, but for much less cost.
Happy to find this medication
I'm happy to see that Chewy now carries this brand of tablets for my dog! They contacted my vet for me and quickly shipped the tablets to me.
Medicine for zoey
Didn’t get it yet! Waiting for it to come. Love getting Zoey medicine in the mail.
Great results, less $$$
This product works! Why pay more. It is safe and effective.
Prescription from Chewy
Been buying these for years and must say the chewy service was great and the price was 25% less than my last purchase from another online pet supply company!
