Great price and convenience

I'm soooo glad Chewy offers pet insulin! My CJ is newly diagnosed and I was 'surprised' at how quickly his vet bills have added up. A friend told me about Chewy and the difference is so much appreciated! Unfortunately our first shipment was delayed a day (I'm guessing due to bad weather on shipping day - major storms in the warehouse area) and although the insulin was packed with coolant, it wasn't fully sealed so some cooling ability was lost as a result, we still got the insulin while somewhat cool. I ran it to the fridge and after a few days' usage am certain all's well.

Fast and excellent service!

I usually don’t leave reviews, but I wanted to express my gratitude for Chewy’s fast and secure delivery of my pug’s insulin, as well as the great price! Having a diabetic pet can be expensive, and I appreciate Chewy’s lower prices (compared to my vet), fast delivery, and excellent selection of products to fit my pet’s diabetic needs! Her insulin was shipped and received in one day and was packed well and chilled. Thank you, Chewy!

Making medicines more affordable

Being able to afford diabetic medicine for my dog has been a struggle, and with her resistance to the insulin causing the dose to increase, well, it can be tough. When the price at my vets office went up $25 per bottle I had to find an alternative and Chewy was the place. Chewy saves me over 30$ a bottle compared to our vet. Thank you.

Same product, better price, free delivery

I have been using this product for over a year for my diabetic cat and buying it from my vet. The vet went up on their price and I decided to give Chewy the opportunity to gain my business, yet again. It arrived cold and saves me about $120 per year! Thank you! When you have an aging pet, you need all the savings you can get! They haven't disappointed me yet.

Chewy is the best!!

Hands down the best customer service on top of everything else! First time ordering through chewy and not only are the prices the best around but the package quality was spot on! Was a little nervous with it being insulin but it came packaged great. Even received a small free gift package today! They go above and beyond no exaggeration, wish i had been ordering a lot sooner you guys are awesome! Thanks again Chewy

good product

Great product which my dog needs but it took very long time for me to get the product. There was mis communication between Chewy and my vet. My vet said they never received Chewy's email the first time it was sent. I hope the service will be better next time for I want to get this insulin from Chewy on a regular basis. Thank you Gennie Fischer

Packaged to stay cold

I was a little concerned about how cold the insulin would be after arriving but it was packaged to insure insulin would be kept as cold as possible. I was very pleased as was my fur baby.

Cat allergic

13 year old cat developed an allergy to this insulin. Vet thinks because of porcine. He was over grooming his front legs and even ripped out some fur! Switching to ProZinc. Hope we have better luck with that. Came with two Nordic ice packs in a padded box! Fast delivery and packaged with great care.

it's about the shipping of Vetsulin

I was concerned re the need to keep it chilled in transit. However, Chewy's packaging & chilling exceeded my expectations! No worries for me ordering again from Chewy :)
