My dog is very picky. She likes Tri-heart chewables. I cut it in 4 pieces and tell her they're goodies, & she eats them. Allivet gives great service.
These Chewable Tablets have kept our Jenny healthy, for the past 8 years. They were recommended by our awesome veterinarian. Thank you Allivet, for your GREAT customer service!
I switched from HeartGuard to triHeart Both Same ingredients. Switched our 12yr St.Bernard =English Setter Mix and is 128lbs But sometime since older after give the med to her she would have stomach upset and cough. Had vet approval. After switching to this she didn’t have tummy upset and didn’t have cough after taking. Our 2yr St.Bernard doesn’t have any problems with either
This product works great for my XXXL Great Dane!
My Baby needs this medicine for her heartworms treatment
I have been buying Tri-Heart tablets from Allivet for my two dogs for so many years. They work as well as the more expensive medications. Shipping is free for Tri-Heart. Allivet always gives fast and reliable shipping.
I’ve been using this product for almost 10 years and it’s worked wonderfully for my dogs. They love the taste and it’s so easy to give. Every year they are heartworm free.
Love the free shipping!
I have been using Tri-heart plus since moving to Georgia two years ago. The price is right and it works!
To keep my dog safe!
The price is right and it’s FREE shipping for this order!
This product, originally prescribed for my last fur baby, kept her free from parasites. She lived to be 15 yrs. old. Also, Allivet offers the best, most cost effective prices as well as prompt, efficient delivery, right to my home.
Excellent price, same ingredients as more pricier products, my dog finds it palatable
Keeping my pets healthy, with top brand pet meds, that don’t cost me an arm and a leg.
Cheaper than Heartgard! Love this product.
I have been using this online Pharmacy for years. Reliable, prices are great, shipping costs are usually $0 and they get authorization from Family vet pretty quickly. Orders arrive usually within a week's time.
Great pharmacy for animals
Great trustworthy medication for your pet.
the price is unbeatable
I did my research comparing what each medicine kills and price and he best deal is to buy Tri-Heart Plus.
EAy and fast, MY Buddy Dog loves them too.
My dogs are "picky" when taking medication. Had a hard time finding a brand they will willingly eat without difficulty. This is it.
Very happy that i found your site,
Works as it should!
My dogs have done very well with Tri-Heart Plus, and they take it as if it was a treat. We are all happy, dogs and family! 😊
The price was the lowest and ordering was simple.
I had no idea I could get Tri-heart to do the work of the Heart#@#@ brand at a fraction of the price. Am so have found this and Allivet is great at getting this to me on time every month.
Reasonable price for reputable product
Gives me piece of mind, my pets are healthy and well overall.
Cost effective and good product
no problems with ordering and best price
Prompt and simple
Best prices. Easy and they follow up if Vet. hasn't sent the approval.

My dog loves these and he is picky!

Love Allivet! Always has what I need at a great price, and free shipping!!
Effective product
This is a great price for this product. It was also easy to add my Vet when she moved. The company will confirm it. Love when things are easy!
GREAT PRODUCT USED FOR YEARS
Great product - cheaper than Heartguard!
Excellent protection from heart worm! Have used this product with perfect results for the past 7 years.
Great way to keep your pets safe
Received my shipment instantly!
good price, works well...
Good product. My dog has no reaction to it.
2nd best to Heartgard! My fur baby has been on this one for about 4 years. Never had any issues with this medication.
works great
Did a search for this product for my boy and this was the best affordable price and product for him.
Great product at a great price!!
no problem feeding them TriHeart Plus
It is more affordable for me.
Same as Heartguard but vastly less costly
My puppy's mom died from Heartworm so keeping them safe is an absolute need for me. Thank you Allivet for helping do just that.
dog eats it out of my hand and way cheper than vet and dont have to make an oppointment
My dog loves the test of this product so I have no trouble getting her to swallow the medicine. No adverse reaction to the medicine and she hasn't had any heart worm problems.
Used for years
service and price!!
same meds as HeartGuard plus but much less expensive
This was recommended by a good friend and animal lover as being the best product!
Reasonably priced heartworm meds for both my dogs...
Great product having been using for years
Allivet is AWESOME! Amazing customer service, fast shipping and GREAT PRICES!
Our dog actually takes this medicine so for that reason alone it is worth 5 stars. We battled for nearly a year trying to get our dog to eat another brand of heartworm medicine and nothing worked. NOTHING. She became a master at eating the food around even a tiny piece of the former medicine and would spit the piece back up. Tri-Heart is different. She actually eats it without hesitation and is a tad less expensive too. Win/Win!
Allivet has the best prices, service and products. Tri-Heart Plus is exactly the same as more expensive brands and it keeps my sweet puppy healthy year round. Allivet is my go-to site for Lucy's healthcare.
I use Allivet for the convenience and quality of their products. Tri-Heart Plus chewable tablets makes me feel like I'm doing the best for my fur baby. And Allivet's customer service is outstanding!
Very efficient, caring. Let's you know when vet approved
Good price
It works for what it is supposed to do.... Supposedly
Good products at a fair price!
more budget friendly than buying from the vet
Best price and free shipping. They contact the vet to get prescription
This is my first time buying the product and while I won’t know for a while how effective it is at preventing heart worm, my dog ate it just fine and doesn’t have any problems with the digestive worms it also prevents. She is an outdoor dog. The service from Allivet.com has been great. We had to work with getting my vet registered and had some back and forth about getting the vet to send the prescription, but Allivet was helpful.
previously taking trifexis, very expensive
Love this stuff. She eats it no problem and it provides perfect protection for a generic price
easy to administer to my dogs and covers both heartworms and hookworm infections
Have used this heart medication on all my dogs with no problems. It is priced right also.
We have 4 dogs
The price is right
Simple, fast & economical!
Does the job and I can hide it in his kibble!
Can't beat the price.
Best price around
My pet loves them. I love the easiest to give him.
easy prosses , fast shipping
My dog likes them
Fast, quality meds for less. Will contact Vet when needed.
Excellent price. Same protection as the more expensive brands. Fast shipping.
Awsome
Beats prices at the Vet's office.
Vet recommendation
Best price.
Received order quickly.
I want my pet protected by any means necessary
Their prices are unbeatable, quick with delivery n the auto ship is a plus!
she was taking trifexis which is very expensive
works for zues-no problems
Zero stars on this product. Both dogs had skin issues right after taking this product, Starts out as itching and chewing, red,-raised hot spots, then skin crusting over, hair falling out, black scab in center with white crusty build up around the outside. Funny because we have used other ivermectin products.
good price
reasonably priced, qualifying medication
