I'll get whatever my dog needs and happily get it through Chewy but the whole insustry seems to be moving in the wrong direction while exploiting our devotion to our soul mate animals. I imagine there are good intentions lumped in with the fear based ones that have led to such a weird time in veterinary culture, however our pets teach us that love, not the exploitation of peoples's fear, is what creates true wealth in this matrix.

Simparica Trio covers outside dangers

I don’t have to worry about outdoor pests that will harm my dog with Simparica Trio on board. With so many different outdoor pests and insects I don’t need to worry about my dog Scout playing in the yard. He is well protected and that gives me relief. Vet bills can be high for even the smallest incident with a dog or cat. It’s great to have a broad spectrum prescription for my Scout. It works very well. It’s one less thing to worry about. Thank you. Leslie V.

A necessary evil

I love my dog and I want her to be healthy. I also don’t want fleas or ticks in my house. So I buy this monthly preventative. The price has gone up in the 4 years

I love my dog and I want her to be healthy. I also don’t want fleas or ticks in my house. So I buy this monthly preventative. The price has gone up in the 4 years I’ve had my dog from $170 to like $213. But what can a pet owner do? It’s also annoying having to mail the prescription in instead of scanning or having my vet send it. But whatever. I get a few bucks back from Zoetis Pet Care for purchasing it, which takes away the sting a bit. Anything for Cheesecakes though!

Super Customer Service

I called to check on returning our dogs last prescription of Simparica since he had just been euthanized. Not only did Chewy give me a complete refund they requested that we Donate the prescription to a local Vet or Humane Society that could use them. In addition to the refund and donation, they also had a local Florist deliver Flowers to our house recognizing the loss of our beloved family member.

Somehow, some way, Mikey gets fleas. I’m sure it’s from his outside potty breaks, but it’s a huge problem. We also have two cats, so if one critter gets fleas, they ALL get fleas. It’s the unwanted gift that just keeps on giving. I’ve tried soooo many topical flea treatments in Mikey. And not a single one took care of the problem. My mom told me she uses Symparica trio with her three dogs, and it works great. So, at Mikey’s vet visit, I got some. Not only did it work, it worked IMMEDIATELY. That morning, he was itching like crazy, and that evening, he wasn’t! He also ate it without an issue, which calmed my initial worry of him not getting a full dose due to not liking the taste. It gives me piece of mind to know it protects and treats worms, as well! I paid $200 for a 6 month supply at my vet’s office. But seeing the discounted price on Chewy is GREAT! I’ll be ordering here from now on. We will never go back to other treatment brands again! This is a game changer!

Our simparica trio was caught up in a compromised card fiasco. We had accidentally missed a month of the preventative care and were now going on a trip to a farm, no less. Our pet Marco needed protection from ticks! After two seconds of trying to update the card on the web and getting confused, I decided to call the customer service number. The woman who answered was not only sweet, but professional and swift fixing the problem. It was a pleasure to come across someone who enjoyed her job and simply put her best forward. I feel like Chewy not only takes care of our pets, but cares about their employees too! Thanks for helping me and making it a great experience.

We found 2 ticks on Abby over the last couple of months so I looked up Abby's monthly heartworm/flea medication and realized that ticks weren't covered. I decided to switch her to a med that covered ticks too. I belong to a Facebook group for Miniature Australian Shepard owners and had heard a lot of people say this is a good med, so I emailed my vet to ask if we could switch her over and was told she had heard many great things about it. I told her to expect a request from Chewy. com. So after Abby took her last of her other meds, I went online to Chewy and ordered it. I got a response back within a day or two that it had been approved and shipped. Another big plus is that this drug can be taken by dogs with the MDR1 gene. Although Abby does not have the MDR1 mutation, there are many dogs that do (especially in this breed and other collie-type breeds.) If you are concerned about that, you can safely give your dog Simparica Trio.

We've used simparica for years. Unfortunately, a few days after ordering, we had to put our dog of 14 years to sleep. I hadn't opened the package yet so I asked if I could send it back. Chewy credited my account and said I didn't have to send it back so we donated it to our local dog shelter. They were very appreciative. Chewy is a wonderful company and I have recommended them to many people over the years!

I have been buying this product for years. This product cost has risen to over $35 a pill! I found the same product for so much less unless chewy gives me a price match or a price adjustment from my recent purchase, I will be ordering from and it’s a legit company from reviews.
