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.

I have been using this product for years and have been very pleased with the protection it has given my dogs. The price was good and having it delivered is a plus.

The price is excellent!

I purchase Tri-heart plus for my dogs and it works well. Fast shipping and reasonable price.

Quick delivery

They sent the prescription to my vet right away. I was very pleased with the speed of this and shipping. I always find the best prices on EntirelyPets, both the pharmacy items and regular product. Thank you!

Fast efficient service and great prices

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.

entirely pets made it so easy. they called vet for prescription and mailed it directly to me!

Good prices. Fast service & delivery. Company contacted vet for Rx. Been using product several years no problems.

Have been using for years great price

Given the negative reviews, I was worried about ordering from Entirely Pets Pharmacy. I'm glad I decided to give them a chance. The process was seamless, the expiration dates on ALL the meds was fantastic - over a year, my order was received in just a few days, and best of all, I got the price offered on the entire Internet. No one can ask for more. Thanks - Entirely Pets !!!!!!!

I've used tri heart plus for 5 yrs and like the product. Was a good deal.I like that they offer coupons and using Rakuten saved me even more money. I would shop with EntirelyPets again!

A simple, quality product to prevent heartworm at a reasonable price.

This is a great product! The generic version is less expensive and hopefully will work as well as the Advantix product. Easy transaction and fast shipping.

Same ingredients and less expensive than anywhere else! Dogs eat it just like it's a treat ! Won't buy any other brand !

If you watched them, you might believe I had fed them a treat. They just gobble the pill up! No muss, no fuss!! Thanks.

Same product as have been using @ less cost.

Great Product

Best price I have found.

Great price. Easy ordering. Timely delivery

Best price when compared to other online stores!

I had not heard of this brand before, but I hope the product is as effective as some of the more expensive ones.

Never have an issue with entirely pets rx program.

Price was great and received so quickly

Ordering was convenient. They contacted the vet for prescription. delivery of the meds was on time and in good order. Have been doing this for a while now and am happy with the service.

Easy online ordering. Though it's not a normal soft chew medicated treat, my dog enjoyed the taste of the product.

I have been giving it to my dog ever since he had to start. He likes it and gives me no trouble when he takes it. Always good lab reports too.

Always order here prices are great

Easy to order! EntirelyPets worked directly with my dogs vet to complete the order. My dogs like the product and enjoy with peanut butter! Works great!

Easy to use and dogs love taking it once a month! Price is right! So much better than the overpriced bigger name brands! Works great! Switched to tri heart years ago and have continued using since. Would highly recommend!

I've been using this for my 10 lb chihuahua for 5 years. Per a Vet's recommendation, I use a 6 month supply which lasts one year-by dividing each pill in half. It works great! Also, Entirely Pets Pharmacy was the best price on-line! Thanks so much.

I have given Tri-Heart Plus to all my dogs for years. It is less expensive than the name brand and entirelypets.com staff are great and so patient with the vet offices.

good price, good product. at least this isn't killing dogs like tri-flexis

This Heartworm medicine was recommended by my vet and price is 1/3 less than at my Vet's office. The order process was very easy. I placed the order. The pharmacy contacted my Vet and I had the product in a week.

I liked the fact that they checked with the doctor to make sure what I was ordering was correct, then informed me of suggested change. At that time I also received a reduction of the cost because of the promo E-mail I had received. Good deal!

Your price was the lowest that I found on- line and the product was delivered in a prompt manner. Very satisfied with your on-line pharmacy! I would use your site again for ordering product for my dog. Thanks!
