Easy to Use & My Dog Loves It

I've never bought any other brand when it comes to complete coverage for my dog. Heartgard chewables have everything I'm looking for in a product that protects my dog from so many biological threats, and my vet recommends it! PetCareRx makes it easy to order, too, which is a big bonus. They work directly with my vet and always make sure that he's up to date. I like to get a 12 months supply at a time, and giving my dog one of these tasty treats once a month is super easy. Each 6 month pack comes with stickers you can put right on your wall calendar. Every dose is also labeled by month (JAN/JUL, FEB/AUG, and so on), so it's easy to make sure you don't miss one! The best part is that my dog looks forward to them. He loves them, and he knows that it's a special treat because he only gets one per month. by on 10/14/2020

heartgard plus

Our dog was from Guild Dog for Blinds. It was recommended by them for our dog when we adopted him. It does need prescription from your vet. Our dog is now 8 years and never have any heartworm issues. He loves it. I used it as a treat once a month after giving fleas treatment, teeth broth, ear cleaning. but then, my dog loves all kind of food. It is a good product and I think every dog should have it once a month. by on 09/27/2020
