8 Best Online Pet Pharmacies For Dog Meds

8 Best Online Pet Pharmacies For Dog Meds
Written by Laura Hall

If your dog has been diagnosed with a condition that requires ongoing prescription medication or you’re looking for a place to buy over-the-counter products like supplements or antihistamines, online pet pharmacies are a super convenient way to get your paws on whatever you need.  

Even if your dog doesn’t have a long-term condition, every pet gets sick at one time or another, and it’s a great idea to have a place in mind to get their prescriptions. Getting them at the vet’s office is fine, but their prices are often extremely inflated.

The vet office’s selection of non-prescription meds is also usually limited and drastically over-priced. Plus, they usually only come in one form (tablets). By ordering through an online pharmacy, you can find what works best for your dog, which is great if they’re fussy with tablets, and save a boat-load of money.

Let’s take a look at our best online pet pharmacy recommendations, starting with our top picks – 1800PetMeds & Chewy Pharmacy, plus answers to some frequently asked questions. 

Top Picks

8 Best Online Pet Pharmacies For Dog Meds

Best For All Needs: WalmartPetRx 

WalmartPetRx, also known as the Walmart pet pharmacy, accompanies their regular store, which needs no introduction. If you want to kill two birds with one stone and order your pet’s medication at the same time as the rest of your supplies, this is the one for you. 

What we Love…What We Don’t Love…
Super affordable OTC pet medsConfusing to set up
Free shipping on orders over $35May need to visit store for some meds (see below)
One-stop shopping for everything from pet supplies to groceries

Who are they? Walmart is one of America’s largest supermarket retailers known for their reasonable prices. They were founded by Sam Walton in 1962 and branched out into the online pet pharmacy world in 2019. 

What makes them unique: Walmart carries supplies for every area of your life and their pet supply section is no exception, carrying over 3,000 items in stock for dogs, cats, fish, birds, horses, and other farm animals, including medication, all for a good price. 

What we like: Walmart is known for their great deals and offers, and the pharmacy provides free shipping on orders over $35, with a 5% discount on auto-ship orders. Prescription orders come with a 100% satisfaction guarantee and swift delivery. 

What to consider: Walmart is a supermarket, not a pet specialist, so while they offer thousands of products, their website has a lot fewer search filters, making it a little more difficult to find exactly what you need. 

Plus, it seems that they’ve shut down their old website, WalmartPetRx.com (so if you see a blank page there, it’s not just you). The current link includes the word “interim” in it, so it’s entirely possible that they’re working on something new. We’ll keep you updated.

Cost Comparison of Common Pet Meds at Each Pharmacy

Let’s finish this off with a side-by-side look at how much some of the most common dog medications will run you at each online pet pharmacy. Here’s what I compared:

The prices below are, of course, subject to change at any time. Depending on coupons, sales, rewards cards, etc, you may actually pay less. But this should give you a general idea of what to expect.

Online Pet Pharmacies comparison chart


How do online pet pharmacies work?

Online pet pharmacies work the same way as online pharmacies for humans. You can order any over-the-counter medication you want straight to your home, as well as prescription medications. To prove your dog’s prescription, you may have to upload a photo of it and/or give your vet’s info so that it can be verified. 

What can you order from online pet pharmacies?

You can typically order over-the-counter medications like flea and tick treatments, deworming medications, and antihistamines, as well as prescription medications like antibiotics and oftentimes holistic products, supplements, and everyday supplies like food and shampoo.

Are online pet pharmacies safe?

Licensed and accredited online pet pharmacies are perfectly safe, but you must stick to recognized pharmaceutical websites. Never buy medication from third-party sellers and if your pet’s medication arrives damaged or opened, throw it away.

How do you know if an online pet pharmacy is real?

Real online vet pharmacies will be accredited and licensed. If you’re unsure, ask your vet for their recommendation or anyone you know who uses one. Alternatively, you can use our list or do further online research to see what other trusted websites & pet parents suggest.  

Is it cheaper to buy dog prescriptions online?

It’s not always cheaper to order your dog’s prescriptions online, but it often is. Most online pet pharmacies have sales and deals periodically and offer some kind of discount if you order products like flea preventatives on auto-ship.

Can I get pet meds without a vet prescription?

No, you cannot order prescription medication for your dog without a prescription from a vet. 

Can I get a vet prescription online? 

Some regular vet offices have options for virtual consultations, especially since the pandemic, but there are also online vet services that offer exclusively online appointments and prescribe medications over the internet. 

While this is convenient, we recommend still visiting your in-person vet for annual check-ups and always using an in-person vet when your dog requires an examination or testing. If you are going to use an online vet, make sure they’re licensed and accredited and research recommendations online.  

Does GoodRx work for animal prescriptions?

Yes! GoodRx, the popular coupon and price comparison site for human pharmaceuticals, now works for many pet prescriptions, too. 

Final Recommendation: What is the BEST Online Pet Pharmacy?

If you’re looking for an online pharmacy for your dog’s medication, all of our top picks above are awesome (otherwise they wouldn’t be our top picks, right?). But which is the MOST awesome? That depends! Let me break it down for you a bit to help you decide:

  • JUST looking for affordable prescriptions and don’t need a bunch of other stuff? Go with 1800PetMeds.
  • Shopping mostly for meds, but also maybe a bag of dog treats or a new toy? Entirely Pets is a great option.
  • Need heartworm meds for Fido & Fluffy, dog food, kitty litter, toys, feed for your chickens, and bedding for your iguana? Go with Chewy.

I hope you found this helpful! If you’ve used any of these pharmacies above, let us know in the comments.
