I have great pyrenees & use Simparica Trio monthly. My dogs have not experienced any side effects & I have not seen any fleas or tics on them. They have tested negative for heartworm. Best to go with a brand your vet recommends for the breed of dog that you have.

Ticks don't bite him

This stuff really works. It is expensive, but worth it. We have a farm and we unfortunately have a lot of ticks, since switching him to this (and not just shampoo),

This stuff really works. It is expensive, but worth it. We have a farm and we unfortunately have a lot of ticks, since switching him to this (and not just shampoo), he's had none bite him. We find them walking on him, but never attched. Very thankful he's not at risk for tick bourne illness any longer.

Chewy customer service went above and beyond

I ordered Simparica Trio for my GSD. Fed Ex delivered it to the wrong house and I was not sure where it was. I called Chewy to let them know I may need to reorder

I ordered Simparica Trio for my GSD. Fed Ex delivered it to the wrong house and I was not sure where it was. I called Chewy to let them know I may need to reorder the prescription. They reordered for me and did not even charge me for the replacement. I am grateful and most appreciative of Chewy's generosity. Thank you. And - yes- I'm telling family and friends about Chewy's great commitment to their customers!

Good overall

These work really well for my FrankieCheese. Other meds we'd tried in the past would make him throw up, and at these prices who can afford multiple doses every cycle?

These work really well for my FrankieCheese. Other meds we'd tried in the past would make him throw up, and at these prices who can afford multiple doses every cycle? The only issue I've had is that these are extremely dense and hard. My playful but ends up tossing it around and I'm playing tracker as I search for it and pieces of it throughout my house. My solution has been to crush it with a rolling pin while the dose is still in the bubble pack, then slitting the backing and mixing the powder into his food. He takes the full dose. I don't have search for the tablet, and he doesn't throw up with this. It works and we only know because he hasn't gotten any of the afflictions it is supposed to protect again.

Best treatment once a month

I’ve been using this for my lab for the past 3 years. She had not had any side effects as I do monitor her closely when giving her the monthly dosage. She chews

I’ve been using this for my lab for the past 3 years. She had not had any side effects as I do monitor her closely when giving her the monthly dosage. She chews them well and I’ve never seen ticks or fleas on her. She has feces exams with her physical yearly and no issues with her health. I find this to be the best treatment without using a flea collar that often times causes allergic reactions as they often had on my previous pets. Getting them delivered by cheery is so convenient and actually cheaper than my Vet. I also chewy for her dog food, treats and toothpaste delivery. We are both very happy customers.

Getting too expensive...and my Chewy Rx Order was not filled correctly...

I ordered 2 six-packs of Simparica in both the 44-88 pound and the 88-132 pound. (I have copes of my order as placed). My Vet ok'd my Rx for a total of 4 packages

I ordered 2 six-packs of Simparica in both the 44-88 pound and the 88-132 pound. (I have copes of my order as placed). My Vet ok'd my Rx for a total of 4 packages of Simparica Trio with autoship. What Chewy filled was 2 packages of the 44-88 pound, but only 1 package of the 88-132 pound. I was charged correctly, but, I lost the discount on buying 12 tabs over only 6. I emailed Chewy twice and got no reply for either email Sadly, I'm quite disappointed in how Chewy handled my order and their lack of reply to let me know why my order got messed up. Lesson learned and I've decided to buy my Simparica Trio locally or through another pet Rx online seller. We have 3 dogs and Simparica is a very costly treatment annually so I plan to find a less expensive option for flea/tick and Heartworm treatments once my current Simparica supply runs out.

Big dog tablets. no fuss, no trouble giving

Dog is over 135 lbs, so we need two boxes. Only wish they had ONE BOX up to 170 pounds for larger dogs .. Maybe it would not cost soooo much.

It works like a charm!

Found a bump while petting my dog and discovered it was a tick. The amazing part? That tick was dead, without a single drop of blood in it. This stuff works FAST

Found a bump while petting my dog and discovered it was a tick. The amazing part? That tick was dead, without a single drop of blood in it. This stuff works FAST. I’ve been giving this to my dog since he was old enough and we have never had fleas, or anything else - but seeing that tick made me realize how awesome the product is. For further info, we live butted up to some woods with a creek. P.S. - I have to give the medication with peanut butter or it shoots out like a rocket. So some dogs love it, and some don’t but don’t let that hold you back :)

Less expensive than you’d think

I was originally hesitant to try Simparica Trio due to the initial sticker shock. We were previously using both Bravecto every 3 months and Sentinal monthly to do

I was originally hesitant to try Simparica Trio due to the initial sticker shock. We were previously using both Bravecto every 3 months and Sentinal monthly to do the job that’s covered by one monthly dose of Simparica Trio. When I did the math, I was surprised to see that treating my (2) 100 pound labs would be much easier and cost effective this way. I was a little worried that they wouldn’t eat the HUGE tablet, but they both scarfed it right down... not even sure if they chewed it lol!

Works like it says!

My golden boy has been on this for 2 years without any issues. He usually experiences digestive upset with other products. He just had his yearly checkup and all
