  • Wish we didn't need them...but glad we found them!

    By on

    Our old boy (14-15 years) is in renal failure, and requires subcutaneous fluids a few times a week to help flush out his system. We were taking him to the vet for this, but learning how to do it ourselves at home was much more calming for him...and us (once we got the hang of it!). These bags are the same quality we were getting at the vet, but much less expensive. I only wish Chewy.com also sold the IV kits to go along with it. We've had to find those on another site.

  • Chewy is great, Aspen brand not

    By on

    Chewy makes it very clear that you may receive Hospira or Aspen brand. I have used Hospira brand LR with great success and hoping to get it. However, I received the Aspen brand. I give the Aspen bag 1 Star as it is stiff, deforms with heat during shipping and the sides of bag stick together so you can NOT figure out how much fluids you’ve administered. Chewy please don’t offer Aspen brand as it is sub par. Will not buy again until I can be guaranteed Hospira brand.

  • Perfect Price for Fluids

    By on

    These IV fluids are exactly what I need for my dog. The price is more than 1/2 off the vet price. I was able to use the line and needles from the vet, as they were not available here yet.

  • Thank you Chewy for offering pet prescriptions

    By on

    Lactated ringers is one of my weekly prescriptions. So I am happy that I get to enjoy the customer service from Chewy for my pets’ prescriptions as well as for their usual weekly or twice weekly pet shopping deliveries. Hopefully this will expand further and more varieties of pet prescriptions will be made available soon.

  • Easy-to-read bag, good price

    By on

    I have two CKD kitties (senior siblings) so subcutaneous fluids are a normal part of life. The bag doesn't distort much as the fluid levels drop (unlike other brands), so the volume ticks are more reliable.

  • My preferred brand

    By on

    I prefer this brand over others. The fluid in some bags with thinner material sometimes form pockets of fluid and air or the bags themselves twist both make it very difficult to determine when you have delivered the correct amount of fluid especially when one person is doing the treatment alone. This brand keeps a very level line of fluid as it is used. This bag also has lines half way between the numbers which also makes it easier to see how much fluid has been given. I'm very glad Chewy has made this available and their price is very good.

  • SubQ therapy for kidney kitty

    By on

    Very pleased that Chewy now has a pharmacy that carries this, we use it daily. Shipping was fast, and the price even better than our usual supplier! Auto ship makes things that much easier too.

  • Wish it was DEHP free

    By on

    I've been giving my cat SubQ fluids for many years...I'm really excited to see that Chewy is starting a pharmacy, but I wanted to leave some feedback. REALLY happy you are carrying Lactated Ringers! Would it PLEASE be possible to carry the brands in cleaner bags? DEHP, PVC and Latex Free make me feel so much better when giving to my pet. The bags with DEHP and PVC absolutely wreak of rubber and "pool floaty" smell and I never felt good about administering fluids that have been sitting in plastic that smells so horrid. The clean bags are much better and odor free and I feel good about those and worry free.
