I have been using Allivet for years. My dog's medication is quite expensive, (like nearly double on some of the so called "top pet med sites." I have had little problem... mostly in the beginning. I just call now, rather that use the site. It is easier and I know that my questions or concerns are answered immediately and revisions are put into the computer. This is the way to go if you are ordering an RX, as your vet has to approve it. Service is great and fast. The staff is very friendly and as far as that person who said they use "fake medication." were I Allivet, I would certainly consider suing her or him. That was ridiculous. Doesn't that person have a vet who can say why the bunny was not responding to the medication. Perhaps a different problem?
