Iverhart Plus for dogs is a heartworm preventative that also controls roundworms and hookworms. Iverhart Plus (ivermectin/pyrantel) is a generic equivalent to Heartgard Plus and Tri-Heart Plus. It has the same active ingredients and is the same strength, but it is pork liver flavored like Tri-Heart Plus, while Heartgard Plus is beef flavored. Iverhart Plus is considered to be the #1 generic heartworm preventative recommended by veterinarians.

Better than buying from the Vet. Once Vet signs and sends in, product ships out within a day or two. Great company

Heartworm Prevention Medication: Iverhart Plus
September 11, 2016
I am very happy giving all 5 of our Chihuahuas Iverhart Plus for their heartworm prevention medication. I always have our "girls" checked annually at the vet's office and they all have never had any issues with heartworms. I feel confident that as long as they receive their monthly dosage of Iverhart, they will never have a heartworm problem. They all like the taste and take the medication without any problems and that in itself is a major plus.
ProsAnnual Vet checkups, always negative for heartworms Good price with EntirelyPets Free Shipping Quick delivery

Replacement for Iverhart Max

Vet recommended these as an alternative for the out of stock Iverhart Max and our boxer eats them up without any coercing with treats. Online service from Entirely Pets was prompt and price was great too.

I love that they call my vet for apporval, make up the Rx and send it to me with a minimum of fuss and a maximum of discounts. I would recommend Entirely Pets Pharmacy to anyone.
