Excellent savings for heartworm protection
April 26, 2024
Finally an affordable product for heartworm prevention. I have 4 dogs so this is such a budget friendly option to protect my babies. I have only 1 dog who doesn't like the dry chewable tablet but grinding it up and putting it in wet food solves that issue.
Excellent Service

Better pricing than elsewhere; they took care of contacting my vet for the prescription; kept me updated on status of my order; received in timely manner; will definitely purchase from this company again.

Merchant Response:It's a lot of work to get all the proper Rx approvals, we are pleased to hear you like the pricing and our service.

Love it! It's a small pill instead of a large chew my dog dislikes.

The veterinarian office was difficult to get in touch due to the Holiday's. However, Entirely Pets kept reaching out until the prescription was filled. Appreciate their work in completing this order.

Effective economical product for my pups!
January 6, 2024
Tri-Heart is an effective and economical alternative to other heartworm prevention products. I break up the tablets into two or four pieces, put them in bread or cheese, and my Jack Russell/Dachshund mixes readily eat the medication. I've given the medication to them for 6 months, and they've tolerated it without any issue.
  • Effective, economical, no issues tolerating it.
  • None of which I am aware.

My first experience ordering from EntirelyPets was very good. I switched vets recently and they were diligent in getting the authorization needed for the prescription. The price was good and the order came quickly. Will definitely use them again.

We've typically ordered products for our dog from one supplier; however, because of rising prices, I decided to compare prices across the internet before placing the last order. EntirelyPets Pharmacy, without a doubt, has the absolute best prices. Website is easy to navigate and shipping was quick.

Happy to find a product to fit our needs for a good price! With small dog going with us on a cross country road trip to the South East, we needed protection against heart worm for a month only. It was perfect to be able to purchase in smaller quantity! Also, customer service was great, shipping prompt! Thank you!
  • Much less expensive than many other brands!

I have been very happy with this product in the past, with my 1st rescue dog. I have a new rescue so I ordered her some Tri-Heart. It was a good price and arrived in a short time.
Big pill can be broken into pieces
March 17, 2022
I like that the pill can be broken into smaller pieces so my dog won’t try to swallow a big pill and choke on it. And my dog takes it like a treat. I also like that the back of the box has a calendar to keep track monthly.
  • Pill can be broken into pieces

Tri-Heart Plus for Dogs

Good Product, Good Price. Wish it came with softer tablet, but if did it would probably be more expensive like Heart Gard.

Simple and seems good
September 14, 2021
My dog eats these with only a slight hesitation, so this is good. I do wish they were soft chews, he seems to like those better. But since he was diagnosed with cancer, my vet and I decided that less poison is better for him, thus choosing this two poison pill over those with three or four.
  • Less poisons
  • Dog eats them with only some fuss
  • Still poison
  • Not a soft chew

Tri-Heart Plus for dogs
May 26, 2021
This was my first purchase of Tri-Heart Plus for dogs. I had been using Heart Guard for my dogs for many years. Heart Guard was getting very expensive for 4 dogs. Nothing is too good for my four legged babies. Of course, if you can get something as good for less money, why not? After checking out Tri-Heart, and with vet approval, I decided to give it a whirl. Guess what? Tri-Heart has the same great benefits as Heart Guard. I would definitely recommend Tri-Heart to all dog owners, like myself.
  • Less expensive, works well for prevention of heart worms.

Very nice people but they were updating their system & we were told it was coming on a weds.... they hadnt even sent it yet. one week later it shows up- they waited 1 week bbefore sending it to us .. so the communication is bad with entirely pets

Merchant Response:Hi Julie, Very true. We were having some growing pains. All new pharmacy and shipping software lead to some delays. The team here worked overtime to work through the bugs. Hope to have you back for your next order. Take care.
  • great products --- comparable prices
  • we have ordered 2 times from them... took more than 2 weeks because it wasnt sent for over a week each time...very slow in filling orders...

Entirely Pleased
February 28, 2021
This is my first order with this company and my first trial of Tri-Heart Plus. I usually use Heartgard but my vet doesn't carry it anymore so he wanted me to try Interceptor. My chihuahua has had reactions to several medications so I'm cautious as to what I give her. After giving her the Interceptor for 2 months, each time she would be listless for a few days, just not her usual self. So I found this med. I checked the ingredients (the same ingredients and same amount) as the Heartgard, it had good reviews and a great price. I consulted with my vet. He agreed to authorize the prescription for Tri-Heart Plus and I am "entirely pleased." I will be reordering.
  • Same medication as the Heartgard
  • Great savings on the price
  • My dog wouldn't chew the pill. I had to break it in pieces and add to peanut butter. I would really prefer a chewable treat option, but at this price I'm not going to complain.

This med did not come in a package altogether, rather in packs and parts of packs with different dates. One was labeled, Use First. I don 't like this and in the future, want an entire pack with same dates on all tabs.
  • Med itself seems OK.

Fantastic Experience!
October 26, 2020
I have used several online pharmacies for my pets and, without a doubt, these folks are the best! Since we have several dogs and a cat, buying from the vet is definitely not feasible. I'm so happy I found Entirely Pets Pharmacy! They send a request to my vet and within a day or two (no supposed Covid delays like some places) they contacted me that my order was being processed and then shipped- easy as that! Not only are their prices the best I've found, but their customer support is excellent.

Merchant Response:Lisa, this review warms our hearts and is motivation for us to continue on! We have some big improvements coming in the near future to help get more orders out more quickly and an even better customer expereicne. Thanks for being a great customer. Thanks for sharing pictures of your fur babies, they are cute!

Works, our Yorkie eats it without problem
October 19, 2020
I'm a bit of a pragmatist... first, the product has to work, and while this product doesn't do flea's, it DOES do much more than the standard heartworm / flea combo chew at a much better price. So, after years of buying the other, I switched to this and a separate flea treatment. Could be happier. Second biggie is will she eat it and does it have any adverse effects? Our Yorkie eats it without fuss, no side effects, and she is well protected. Very happy with Tri-Heart and highly recommend.
  • Broad spectrum protection
  • Dog likes taste
  • Price
  • Doesn't have Flea/tick protection (but not really a con, when you work out the price)

July 25, 2020
I've been giving my boy this for over 6 months now. He devours the "treat", so I guess it tastes good to him! I like the fact that the ingredients are identical to Heartgard plus, but this is more affordable for me. Shipping was reasonably quick after getting authorization from the vet. This is a great product.

Merchant Response:Melody, you have a very cute dog!
  • Affordable, tasty
