Heartgard for regular Dogs

We use Heartgard for Regular Dogs because it's effectiveat preventing heart worms in our Doxies. We've tried other brands and Heartgard is best priced, especially w/five Doxies. by on 03/17/2016
good results

We've been using this brand for many years, which is also what our vet uses/recommends. None of our dogs, over this long period, has ever had any problems. by on 02/27/2016

Great product. Not really any cheaper here than anywhere else. by on 08/11/2015
Good product; not a good place to purchase.

This product was cheaper at my vet's office! To purchase online you still need to get a RX from your vet. Also, since February, heartworm medicine can not be sold without an annual test for heartworm so you still have an expense at your vet's. by on 05/11/2015
Ease of administering

My dogs view their monthly heart guard treatment as a treat and when I get out the box there are wagging tails and eager faces. Then they want a second piece of heart guard. by on 12/15/2014

really easy to give and for the pups very easy to take .:) by on 05/15/2014
Just what the Dr. ordered

My dog loves the flavor of these. She thinks they are a treat. I was in need of them during a promotional period and thought I would give Petcare RX a try. Setting up the Vet info for the first time was the toughest part but got straightened out pretty quickly. The product arrived in less than a week. As a repeat customer, reordering is a breeze. I find the cost in line with buying local so with free shipping, the convenience of ordering online is great by on 04/18/2014

Heart Gard

This medicine is very good for your pets and they like the taste. They want to take it rather then having to force them to take the medicine by on 04/15/2010
Heartgard Purchase

I purchased Heartgard from PetCareRx and it was easier than getting it from my local vet and a lot cheaper. I ordered the product in the evening, PetCareRx called my vet the next day, and I had the product on my doorstep within just a few days. by on 04/26/2008
