If your dog takes medication regularly, you’ve probably discovered that pet prescriptions can get expensive in a hurry. Whether it’s allergy medication, pain relief for arthritis, heart medication, or a long-term prescription for a chronic condition, every refill adds up.
The good news is that you don’t necessarily have to buy those medications directly from your veterinarian. Online pet pharmacies often carry the exact same prescription medications and ordering them can be just as simple once your vet approves the prescription.
One thing surprised me while researching this article, though. I expected to find huge price differences between pharmacies. Instead, for many of the most common brand-name medications, the prices were nearly identical across every retailer I checked.
That means choosing the best online pet pharmacy isn’t really about finding the absolute lowest sticker price. It’s about looking at the whole experience, including convenience, shipping speed, refill options, customer service, and any extras that make managing your dog’s medications easier.
Here are the online pet pharmacies that stand out the most.
At a Glance
| Pharmacy | Best For | Prescription Service | Autoship | Why We Like It |
|---|---|---|---|---|
| Dutch | Best Overall | Yes | Yes | Telehealth and pharmacy in one place |

Quick note: I included screenshots of the dog prescriptions section for each pharmacy just to give you an idea of the overall layout, user-friendliness, etc. Any with prices or discounts shown are subject to change (and most likely will change) at any time.
Since the base price is the same for most medications, I’m including a little section on what types of discounts they offer. These are also- you guessed it- subject to change at any time. 😀
Best Overall: Dutch Pet
If you’re looking for online vets who write prescriptions and who also sell those prescriptions in their own pharmacy, Dutch Pet is the one you want.
Instead of scheduling a traditional office visit just to renew a prescription, Dutch lets eligible pet owners consult with a licensed veterinarian online. If medication is appropriate, the prescription can often be sent directly through Dutch’s pharmacy, making the entire process surprisingly seamless.
For dogs with chronic allergies, anxiety, arthritis, skin conditions, or other ongoing health concerns, that convenience can be worth just as much as saving a few dollars.
You can also shop their pharmacy using an existing prescription from your vet, giving you the best of both worlds. Plus, when you sign up for a Dutch membership, you’ll get $25 in credit to use in their pharmacy.

What we like
- Veterinary consultations and pharmacy in one place
- Easy prescription renewals
- Excellent for long-term medication management
- User-friendly website
- Competitive pricing
What to consider
- Not every condition can be diagnosed through telehealth.
- State regulations may limit which services are available.
What types of discounts do they offer?
Along with the $25 credit for signing up for a membership, Dutch offers discounts on certain non-prescription items throughout their store throughout the year. For example, right now they are offering a 20% discount on flea and tick meds with an annual membership. They also have a 20% discount on all Purina Pro products, and 30% off your first autoship for a ton of other products.
Dutch offers ongoing telehealth care for dogs, not just quick advice. You’ll get personalized treatment plans from licensed vets and, in many cases, prescriptions delivered to your door. Ideal for managing chronic issues like allergies, anxiety, and skin conditions without constant in-person visits.

Runner-Up: Valley Vet
Valley Vet has been around for decades, and it’s one of those retailers that experienced pet owners have quietly relied on for years.
While it’s well known in the livestock world, Valley Vet also has an impressive selection of medications for dogs. During my comparison, its prices on common brand-name prescriptions were essentially the same as the other major retailers. Where Valley Vet really shines is selection. It often carries medications, supplements, and veterinary supplies that can be harder to find elsewhere.
If you already have a prescription from your veterinarian and simply want a reliable place to order it, Valley Vet is an excellent choice.
What we like
- Huge medication selection
- Competitive pricing
- Carries many hard-to-find veterinary products
- Long-standing reputation
- You can have them contact you vet or you can have your vet call or fax them the prescription. They even let you mail in a written prescription (although that would take a bit longer).
What to consider
- Website is geared towards horses and livestock. They offer all (or at least almost all) of the same prescriptions for dogs as other pharmacies, but you just have to click a few more times to get to them.
What types of discounts do they offer?
In addition to autoship discounts on most meds, Valley Vet also often runs promotions to save $X off $Y (for example, they did $25 off $250 during their 4th of July sale) as well as special discounts and deals when you sign up for their newsletter.
Valley Vet has been a trusted source for veterinary supplies and pet medications for decades. Along with competitive prescription pricing, it offers an impressive selection of medications, supplements, and health products for dogs.
Best for Convenience: Chewy
There’s a good chance you’re already ordering dog food from Chewy, so adding prescriptions to the same order makes a lot of sense.
Chewy makes it easy to upload or transfer prescriptions, and its customer service has built a loyal following for good reason. If there’s ever an issue with a prescription approval, their team is generally quick to help resolve it.
Combined with Autoship and fast shipping, Chewy remains one of the easiest online pharmacies to use. That said, I still give the edge to Dutch and Valley Vet when it comes to prescriptions. Both are more focused on veterinary care and medications as their primary mission, and other pet-related items as a secondary offering.
Chewy (along with PetSmart and Petco) are kind of the other way around. They offer pet prescriptions as one part of a much larger pet retail experience, with their primary focus being on food, treats, toys, etc.
What we like
- Outstanding customer service
- Simple prescription transfers
- Fast shipping
- Convenient Autoship
What to consider
- They reach out to your vet to get approval. While this is super convenient, sometimes it’s easier to just have your vet contact them from the get-go instead of only if there’s an issue getting in touch with them. Especially if your vet happens to be a super busy clinic like the one we use.
What types of discounts do they offer?
The best deal is the 20% discount on your first Rx order. They run that special pretty much year-round. Chewy also offers autoship discounts on many medications, although that discount varies quite a bit. For example, for Apoquel, it’s about $1.50. For Simparica Trio, it’s between $6-10.
Chewy makes ordering your dog's prescription medications simple, with an easy prescription approval process, fast shipping, and excellent customer service. If you already buy your dog's food and supplies from Chewy, adding medications to the same order makes managing your pet's care even more convenient.
Best for Existing PetSmart Shoppers: PetSmart Pharmacy
If you already shop at PetSmart for food, treats, or toys, ordering prescriptions through its pharmacy keeps everything in one account.
Its medication selection covers many of the prescriptions veterinarians commonly prescribe for dogs, and the ordering process is straightforward. Frequent promotions and loyalty perks can sometimes add extra value, even when medication prices themselves are similar to competitors.
What we like
- Easy ordering
- Good selection
- Frequent promotions
- Convenient for existing customers
What to consider
- They are another one that reaches out to your vet for you. Again, great, but not as convenient as giving you the option to let you vet contact them.
What types of discounts do they offer?
PetSmart offers 35% off the first order + 5% off subsequent deliveries when you choose autoship for your pet meds. The catch is that the max discount is $20. So if you’re ordering, say, a month’s supply of VetMedin (one of the most expensive heart medications, and I know this because Freya is on it now), you’re not getting a full 35% off.
PetSmart Pharmacy makes it easy to order your dog's prescription medications alongside everyday pet supplies. Its straightforward prescription process, reliable selection, and convenient online shopping experience make it a solid choice, especially if you already rely on PetSmart for your pet's regular needs.
Best Rewards Program: Petco Pharmacy
Petco Pharmacy rounds out our list with a solid combination of medication availability, easy online ordering, and rewards benefits.
If you’re already a Petco customer, earning rewards while ordering prescriptions is a nice bonus. Like the other pharmacies on this list, pricing on common brand-name medications tends to stay very competitive.
What we like
- Rewards program
- Easy online ordering
- Good medication selection
- Frequent sales on pet supplies
What to consider
- In my experience, my prescription order from Petco took the longest out of our top 5 picks to get confirmed by my vet. That may not be everyone’s experience, though. Like I said earlier, my vet’s office is crazy busy so Petco may have contacted them at a really bad time.
What types of discounts do they offer?
Out of all of the 1st-time autoship deals I’d have to say that Petco is the best. They give you 50% off your first order, up to $50, plus 5% off subsequent deliveries.
Petco Pharmacy offers a convenient way to order your dog's prescription medications online while earning rewards on eligible purchases. With a solid selection of medications, easy online ordering, and the ability to shop for food, treats, and other essentials in one place, it's a great all-around option for many pet parents.
Why Aren’t Online Pet Prescription Prices Very Different?
One thing that stood out during my research was how similar the prices were.
I checked several common prescription medications across every pharmacy on this list, fully expecting one retailer to come out far ahead. Instead, many of the prices matched almost exactly, and those that didn’t were only different by pennies.
That’s because many prescription medications for pets come from the same manufacturers, and licensed pharmacies purchase them through similar distribution channels. Unlike dog food or toys, there’s often very little room for retailers to dramatically undercut each other on brand-name medications.
In other words, if you’re comparing Dutch, Valley Vet, Chewy, PetSmart, and Petco, the base price probably shouldn’t be the deciding factor.
Instead, consider things like:
- Shipping costs and delivery speed
- Autoship discounts
- Rewards programs
- Prescription refill reminders
- Customer service
- Website usability
- Whether veterinary care is built into the experience
Those extras often end up saving more time and money than chasing a medication that’s only a few cents cheaper somewhere else.
What Can You Buy From an Online Pet Pharmacy?
Most online pet pharmacies carry medications for common conditions, including:
- Allergies
- Arthritis and chronic pain
- Anxiety
- Ear and skin infections
- Heart disease
- Thyroid disorders
- Seizures
- Flea and tick prevention
- Heartworm prevention
- Prescription diets (through some retailers)
Many also stock supplements, dental products, and other veterinary-recommended health products.
Are Online Pet Pharmacies Safe?
As long as you’re ordering from a reputable, licensed pharmacy, yes.
Every pharmacy on this list works directly with veterinarians to verify prescriptions before dispensing medication. That means you’re receiving the same FDA-approved or veterinarian-prescribed medications you would purchase through many veterinary clinics.
If you ever come across a website advertising prescription medications at dramatically lower prices than every other retailer, it’s worth taking a closer look before ordering. Extremely low prices can sometimes be a red flag.
Final Thoughts
If there’s one takeaway from this comparison, it’s that choosing an online pet pharmacy isn’t really about finding the absolute cheapest prescription.
For many common medications, prices are remarkably similar. What separates one pharmacy from another is the overall experience.
Dutch earns our top recommendation because it combines veterinary care and prescription fulfillment into one easy-to-use platform, making ongoing treatment much simpler for many pet owners. Valley Vet is a fantastic alternative if you already have a prescription and want access to an enormous selection of medications and veterinary supplies. Chewy, PetSmart, and Petco are all solid choices as well, especially if you already shop there and appreciate the convenience of keeping everything in one place.
Dutch offers ongoing telehealth care for dogs, not just quick advice. You’ll get personalized treatment plans from licensed vets and, in many cases, prescriptions delivered to your door. Ideal for managing chronic issues like allergies, anxiety, and skin conditions without constant in-person visits.
