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.

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 :)

Love Chewy! Chewy's the best!

I was in dire need of Vetsulin for my fur baby. First time to order it from Chewy. Chewy responded promptly....a pharmacist actually called me to let me know it would be shipped sooner than expected which set my mind at ease. They went above and beyond!!!

This company is GREEDY.

I can't provide my review, because it's not appropriate. You know what isn't appropriate? INFLATION. Thanks. I can no longer afford to keep my dog alive.

Literal lifesaver.

Our Doxie was recently diagnosed with canine diabetes requiring two shots/day. We travel throughout the USA, and maintaining a supply of this lifesaving fluid is a challenge, but the rapid shipping and extra care given to shipping this to wherever we are has been terrific. I have included a picture of the excellent packaging they provided for this refrigerated medicine.

Need more info

I had accidently left a bottle out of the refrigerator overnight. OMG. I looked at the insert and it made no mention of this at ALL. It is a disturbing thing to do, since it only says to refrigerate, not what to do if the temperature of the med is not maintained as noted in the insert. Is the med still good? Is the dose still accurate? Is it harmful to give? What are the consequences of doing this? Will the control of the sugar be good or less than if it had been kept refrigerated? So many questions. It is not CHEAP... Do I have to get another vial? No answers are readily available. This info NEEDs to be added to the printed insert. Why is it NOT????????
