While I am weary of online medication sites this one has proved many times to be a good company. We order my dog's heartworm medication, flea and tick prevention and other odds and ends here. They work with my Vet to get the proper prescription, and shipping is relatively quick (about a week total for processing/delivery). They even have her dog food, a limited ingredient diet, so when I get coupons I can use them on a variety of items. This site came through when my dog needed an antibiotic that my Vet couldn't give me because it was backordered. I saved over half the cost going here vs. a regular pharmacy (where the Vet sent me) to get my girl the meds she needed. This site accepts Bill Me Later which is super helpful if you have that account and are in a bind for your pets' needs. The shipments come with clear receipts and a treat for your pup. I have had a couple issues with their site not loading order status/update information, sometimes something would ship and it would not say/show this in my account, resulting in phone calls to find out if there were delays, but the people I spoke with in customer service were helpful at getting me the information that the site didn't have.
