Here’s what consumers have asked with answers from Allivet staff and previous consumers.
Ask your vet for the manufacturer. I ordered 3 meds, all 3 were from same manufacturer as vet-2 were in exact same package, 1 was packaged differently but the quantity was tripled!
Out of 3449 reviews they still have a 4.5 star rating out of 5. I can personally say that I have never had an issue with Allivet on any of the medication that I have had to order for pets and it is much less that what I would pay through my veterinarian for the exact same product. They also have great prices on pet treats as well, which can quite possibly help you get their free shipping offer for spending $49 or more if the medication isn't quite expensive enough.
I've used Allivet for insulin for a cat and thyroid meds for a dog, both life dependent medications, and I've always received the meds on time. Of course, it's the owner's responsibility to order meds allowing a reasonable amount of time for processing and shipping, you can't wait until you're out to order.
