Beef-flavored Trifexis (spinosad + milbemycin oxime) chews are prescribed to eliminate fleas and keep flea infestations from happening. They also protect against heartworm disease as well as treating and controlling infections of adult hookworm, whipworm, and roundworm in dogs.
Because Trifexis chewable tablets are beef-flavored, so your dog will think you are giving him a treat. The convenience of flea control medicine, heartworm prevention, and intestinal parasite control in one flavorful flea and tick pill lets pet parents rest easy knowing their furry companions are protected.
Your pet must be tested for heartworm before administering Trifexis tablets for dogs. This is an important test and helps protect your pet from heartworm and ensures they get the correct treatment.
The most common side effect of Trifexis chewable flea control is vomiting. However, there are some other adverse reactions you should know about if you are considering giving Trifexis to your dog. If these side effects become severe or concerning, contact your veterinarian.
Additional side effects of Trifexis include:
If your dog is taking other medications in addition to Trifexis, talk to your veterinarian, some medications can react badly with Trifexis.
If your pet is allergic to Trifexis, they may have symptoms like seizures, scratching, hives, vomiting, sudden diarrhea, shock, cold limbs, pale gums, or coma. If your dog has any of these symptoms, speak with your veterinarian or an emergency veterinarian right away.
Your veterinarian should know about any other medical issues your pet has, especially epilepsy. Some conditions may make it unsafe for your dog to take Trifexis. It may not be appropriate for pregnant dogs or very young puppies. Safe use in breeding males has not yet been evaluated.
As with any medication, there is a chance your dog may have an allergic reaction that leads to anaphylaxis. If you notice any signs of an allergic reaction, contact your veterinarian right away.
Easiest way to protect my Little Girl that I love with my life.
My dogs are 7 and 5 years old. They have both been taking Trifexis since they were old enough to take it and neither of them have ever had a tick, flea or any kind of worms. It's a little pricey but for that I'll do it.
Been using this for almost 2 years on my dogs and I am very satisfied! Never any fleas or ticks and they spend a lot of time outdoors at parks around other pets.
This heartworm, flea and tick protection pill has been great. There have been no issues with worms and have never spotted a flea or tick on my dog and we have been giving to him for years. A wonderful product but a little pricey. However worth the cost for keeping our family member healthy. Thank you 🙂
My dog has been taking Trifexis for years & has never had a problem with flees.
I gave all four of my mini Schnauzer’s trifexis once a month without any problems! Great price too
my dog has been on TRIFEXIS for over 3 years. love this product
We have had no fleas or ticks on our dog after starting our dog on Trifexis!
My long hair Dachshund loves these chews as they don't require being disguised, and they have kept him healthy.
Our dog doesn't like these, so we have to hide them inside other food to get them to eat it. As far as we know they are working. They have never coughed or showed any signs of heartworms. The mosquitos don't bother them. I am not sure about if it's suppose to help with ticks, but it seems to. Our dog is 12 years old and has been taking them most of those years.
My dog is not crazy about the taste or smell but I hide it with some almond butter...
HAVE BEEN GIVING TRIFEXIS TO MY POOCH FOR SEVERAL YEARS. THE BENEFITS ARE VISIBLE - SHE'S NEVER EXPERIENCED FLEAS OR TICKS. TRIFEXIS IS GIVEN ON THE FIRST OF EVERY MONTH AT MEALTIME. ALLIVET HAS PROVEN TO BE A RELIABLE SURCE & CHEAPER THAN ANY OTHER ONLINE SOURCE. THANKS TO ALLIVET.
My Dog has been on it for 8 years and no issues. Doesn’t cover ticks but it’s cheaper and we don’t have a issue with ticks so I’ll take the savings
Our dog has been on Trifexis for years. It works great. Unfortunately, our dog hates the taste so it's always a battle to get it down.....cutting it up and covering it with peanut butter seems to work the best.
This product always works well and instantly for my puppy. He easily chews it up, so very easy to administer. And the vet always gives him a "thumbs up" exam with it doing its job towards fleas, ticks and heart worms. Have used it for years with my other dogs too. Highly, highly recommend.
I like Trifexis because it is one pill to prevent both heartworm and other lesser pests. Millie loves the pill, so no problem giving it to her. Once a month and no worries.
This year, I encountered a significant issue with fleas for the first time. Typically, after a flea bath and the application of a topical treatment, I would see quick results. However, this time it was different. I decided to give my pet Trifexis, and to my relief, it was effective. Within a week of treatment, the fleas were gone.
My Yorkie has been taking Trifexis for years, and has been doing great with it. Each year the Vet gives her a clean bill of heath. Allivet Phy has always been the one with the lowest price.
My dogs have been taking Trifexis for years, and I have not had any issues, other than I have to find creative ways each month to get them to take the pills. They absolutely hate them. But I'm pleased that the med is effective. So I'll stick with it...and continue to find yummy ways to entice the dogs to take them!
I have been giving this to my dog for years after being prescribed by my vet. It works and my dog shows no side effects.
My dog has been taking this medicine since he was able, I have had no issues he is 4yrs old never had worms and I’ve never seen a flea heart worm test is always negative. He has never taken a different prescription. If possible try not to change your medication for your animal. I have a Minature Schnauzer male neutered weight is about 15-17 lbs
Works Great! Only flea medication that has worked as a preventative. Topical meds do not work well. If my dog gets fleas while I’ve run out will use Capstar, which works so fast!
This product has worked on my dogs for years. None of my dogs have any allergies to it compared to another brand.
Never had an issue giving our Zo these. She takes them as a treat, with ease. Seems to like the flavor compared to simparica Trio, which we had to force feed her. she spit out every form tried to give to her. I've noted the following text for you: "Never had an issue giving our dog Zo these. She takes them as a treat with ease. She seems to like the flavor compared to Simparica Trio, which we had to force-feed her. She spat out every form we tried to give to her. She loved Heartgard chews as well, they are just too expensive. Price wise and ease of acceptance with the Trifexis, is worth it. Very good product.
This presentation is the best! Cooper loves the taste and it keeps the fleas away. Cooper had no side effects with this medication either. ❤
Trifexis works really well, but my dog HATES the flavor with a passion. I wish Trifexis would come up with a new and improved better flavor, and we would be very happy.
Good product that treats a lot of things at once. However, these pills need to be more palatable .I have to cut each one into 1/4's and wrap in a pill pocket to get the dog to eat them
Seems to work, but had great difficulty getting my dog to take it. I would have to describe its aroma as "chemical" and thereby not very tempting for any animal to eat. Cannot recommend this product.
I love this product. I have been using it for years on my pets. They have no fleas or ticks. Best product on the market.
This product works ... never seen a flea on Tigi and this is also her de-wormer. Great product!
Recommended by Vet. Loretta has never had a problem with ticks or fleas
I’ve been using this medication for 9 years. My pet has had no side effects and has never had fleas, ticks, or other parasites. It’s affordable and easy to dispense.
It’s a flea and tick pill all in one - beef flavored so ur dog thinks it’s a treat. And necessary protection for all dogs. Highly recommend this.
Works well for my dog, no fleas or ticks. My only concern is that the pill is so huge and my dislikes the taste, so she refuses to eat it. I'm not sure if it's too much for her or if the medicine makes her sick, but she always looks sickly afterwards for a few days. Sometimes she feels so sick that she vomits it up, so I am looking for a new pill.
You can't beat the price!
They work as described.
This is an easy all in one heartwarming and flea med ths even picky pups 💕 love
I believe this medication is best choice for my dogs
Excellent product, great delivery and customer service. Love Allivet!
The dogs love them! I have had excellent experiences using this product.
Trifexis works great. My dog has been taking this for about a year and we haven’t seen a single flea or tick on her, and no heart worms either. I just wish it had a better flavor, so that it would be easier to give to my dog.
Works great and even lasts a little longer than expected. I never have to worry about fleas with this product!! And as always shipping is fast and easy, right to my door!!!!
This brand is not carried by my provider and a friend highly recommended this brand for all her pets.
This product has everything to protect our lovely pets and the price is good for the budget
Lowest price found.
My dogs have never had a flea since taking this product.
I have always had a pleasant experience dealing with Allivet.
Been using this product for 14 years, never had an issue
We have gave this to our dogs sense we hade them. it works for us and them.
Works great and our pet loves it ❤️.
It's good to know that you heart worm protection and flea and tick in the same pill. Once a mo
Been dealing with Allivet for quite awhile and highly reccomend this company.
This works like a charm.
Fabulous product. My dachshund swallows pill easily when it's in a small bowl of wet food (her favorite: pate). She has been taking this product for years. _ Best offer is with Allivet!
BEEN USING THIS FOR 10 YRS AND IT WORKS GREAT and i saved money from Allivet
This is medication is the best! You get both your fur babies heart worm and flea & tick medication all in one easy chewable tablet. I have to admit that our Jameson doesn’t care for the smell or taste but it’s nothing that a little peanut butter or cheese doesn’t take care of. I’m so glad someone finally combined both medications into one tablet.
Great product. Does what it is supposed to do.
Works for my dog - good price.
Great product. My dog has NEVER had any issues.
Easy online purchase and great customer service
My dog has no problems digesting it and it seems to be working very well.
It works well to treat fleas but my Mini Aussie hates taking it. I had an issue with auto-ship and not receiving the product. I contacted via Live Chat and worked with Carlos. He quickly responded with sending it out again immediately. Wow, what customer service. I tried to rate his service in the survey but I could not get the info to be input. Excellent customer service from Carlos on 4/21/22 at 4:40pm
This stuff works great...just wish it wasn't so expensive
I like that I can order from home
Trifexis is working for Zoey. It is so convenient to get it by auto-ship service. Thank you!
I have four dogs and this stuff works well for all of them. It doesn’t cause them any discomfort compared to another medication that caused an allergic reaction which included hives to one of them.
Shopping with ease & pricing is competitive!

Best for heart worm and fleas all in one pill.
We called Allivet, asked them to send Willow's Trifexis, & in less than a week had her 6 month supply. We are ready to travel! Thanks Allivet!!
Great product, knocks out everything with one chew. I do have to wrap it on cheese to get her to eat it, nut she's a lil diva.
My blue pit has never been infested with fleas and I'm so thankful to have her on this monthly remedie.
The right one for my puppy.
Great selection and prices!
This is a great medicine! It's all-in-one protection in a safe, easy way! Her vet recommended this medication & it's done great for her for years!
