How Chewy Pharmacy Prescriptions Work (and What to Do If Your Vet Won't Approve)

Chewy ships a prescription only after your vet approves it. Here is how approval works, how long it takes, and what to do if your vet declines.

Quick answer: Chewy fills a pet prescription only after a licensed veterinarian who has a valid relationship with your pet approves it. At checkout you have Chewy contact your vet or mail in the original paper prescription. Vet approval typically takes 1 to 2 business days, and most orders arrive 3 to 5 business days after approval. If your vet declines, an overdue exam, heartworm test or bloodwork means your pet must be seen first. If there is no medical reason, most states require vets to give you a written prescription on request.

How Chewy Gets Your Vet's Approval

Chewy says it fills only prescriptions written for your specific pet by a licensed veterinarian, and sells prescription (veterinary) diets only when a vet has authorized them for your pet. Here is how an order moves from your cart to your door:

1. Checkout. You add the item and enter your pet's details and your vet clinic. The approval options you see depend on your clinic.
2. Choose how approval happens. Chewy says most clinics work directly with it. For those clinics you can pick "Chewy contacts vet", and you won't need a paper prescription, or you can mail an original prescription you already have. If your clinic does not work with Chewy, checkout offers only the mail-in option, though your clinic can still fax the prescription to Chewy directly.
3. Chewy reaches your clinic. Chewy's pharmacy team verifies prescriptions by calling or faxing clinics, and clinics can send prescriptions by fax, mail or Chewy's vet portal.
4. Pharmacist review. Once your vet's prescription arrives, a pharmacist reviews it, usually in less than 24 hours.
5. Shipping. Most prescription orders arrive 1 to 2 days after they ship. Overall, Chewy says most customers get prescription items within 3 to 5 business days once the vet approves.

These are Chewy's typical estimates, not guarantees, and its own help pages differ slightly: one says approval "typically takes about 1 day", another says 1 to 2 business days. If you are close to running out, order early or ask your clinic how they handle Chewy requests.

Mailing a prescription you already have

Chewy accepts only original prescriptions from pet owners. It says it cannot accept photos, scans or photocopies, because of pharmacy regulations. You can drop the original at FedEx at no extra cost, with a QR code or printed label, or mail it yourself with your order number written on it. Use the address shown in your order details, because some medications, such as gabapentin, go to a different pharmacy.

Vet diets, Autoship and transfers

• Prescription diets: Chewy contacts your vet for authorization, which typically takes a day, or you can upload a copy of an existing authorization to your order. Approved diet orders arrive in 1 to 3 days.
• Autoship: prescription and diet items on Autoship save 5% per order. When a prescription or authorization expires, Chewy automatically contacts your clinic to renew it. A prescription's fills and refills can't add up to more than a year's supply.
• Transfers: to move a prescription from another pharmacy, contact Chewy Pharmacy by chat or at 1-877-977-3879 with your pet's name, the other pharmacy's name and phone number, and the prescription number.
• Shipping limits: Chewy currently can't ship gabapentin to some states, including Virginia. Florida and New York are not on that list.

What Each Chewy Prescription Status Means

Status	What it means	What you do
Pending vet approval	Chewy has asked your clinic to approve. Typically 1 to 2 business days.	Nothing yet, unless Chewy contacts you.
Pending pharmacist review	Your vet's prescription arrived. Review usually takes under 24 hours.	No action needed.
Approved	Your order is being prepared. Most arrive 1 to 2 days after shipping.	Watch for tracking.
Mail in prescription	Chewy needs the original paper prescription.	Use FedEx drop-off or mail it to the address in your order details.
Please contact us	Chewy couldn't reach your clinic or needs more information. The order is on hold.	Contact Chewy Pharmacy.
Please contact vet	Your vet wants to talk to you before approving. The order is on hold.	Call your vet.
Declined	Your vet did not approve the prescription, and the order is canceled.	Ask your vet why before you reorder.

Why Your Vet Might Decline a Chewy Request

A decline is not always a clinic protecting its own pharmacy. Often there is a medical or legal reason, and knowing it tells you what to do next.

• No recent exam. A vet can only prescribe for a pet they have a valid vet-client-patient relationship (VCPR) with. State rules require a recent exam, and some set that limit at 12 months. The AVMA notes that when an online pharmacy faxes a refill request, the attending vet may approve it or not based on their medical judgment.
• Heartworm prevention needs a current test. The American Heartworm Society recommends testing dogs 7 months and older (antigen and microfilaria) before a preventive is prescribed, every 12 months after that, before switching brands and after any lapse. Puppies under 7 months can start prevention without a test. See can you get heartworm prevention online without a vet visit.
• Long-term NSAIDs call for bloodwork. The FDA advises checking liver and kidney values before starting a dog on long-term NSAIDs such as carprofen, and repeating them regularly. A vet may hold a refill until that bloodwork is done.
• Controlled or restricted drugs. Some medications are controlled substances, and gabapentin is scheduled in some states, including Virginia. These carry extra prescribing rules. See is gabapentin a controlled substance.
• Compounded medication. Chewy needs your vet to write down the medical reason a compounded version is needed (lower cost alone doesn't qualify), so the request stalls until the clinic adds it.
• Wrong pet, dose or product. Each prescription must be for one pet, and off-label use needs a specific note from the vet.

Steps to Take When Approval Stalls

1. Check the status in your Chewy order. "Please contact vet" and "Please contact us" both mean the order is on hold until someone acts.
2. Call your clinic. Ask whether they received Chewy's request, whether they approved or declined it, and what they need from you.
3. If they need to see your pet, book the exam, heartworm test or bloodwork. It is often the fastest way to get the order moving.
4. Ask for a written prescription. If your pet is current and the medication is appropriate, ask for a paper prescription to mail to Chewy, or ask the clinic to send it to Chewy by fax or through Chewy's vet portal.
5. If the clinic still refuses without a medical reason, ask them to note the reason in writing and mention your state's rule (see the table below). You can also see another vet, or contact your state's licensing board: the Florida Board of Veterinary Medicine, the New York State Board for Veterinary Medicine or the Virginia Board of Veterinary Medicine.
6. Ask about a short bridge supply from the clinic if your pet will run out before the order arrives.
7. Don't have a current vet? You will need a licensed vet to examine your pet before anyone can prescribe, in person or, where state law allows, by live video. A heartworm test or bloodwork always means an in-person visit. Our guide to which states allow online vet prescriptions explains where video can start care.

Your Rights to a Written Prescription

There is no federal law requiring vets to give you a written prescription. The Fairness to Pet Owners Act was introduced several times but never enacted. The AVMA's ethics rules require vets to provide a prescription on request, instead of dispensing, when a VCPR exists and the drug is medically appropriate. The AVMA says most states have laws requiring vets to provide prescriptions on request. Here is how it works where RexVet's vets practice:

Where	Right to a written prescription	After a video-only visit
Florida	Yes, if you ask before the drug is dispensed. Since July 1, 2026, the vet must also tell you about this right before dispensing, and you sign once to confirm you were told.	Live video can start the relationship. Limited to FDA-approved animal drugs used as labeled, for up to 14 days (1 month for products labeled only for fleas and ticks). No renewals, human drugs, controlled substances or compounded anti-infectives without an in-person exam.
New York	Yes, if a valid vet-client-patient relationship exists (state practice guidelines).	No statute specific to veterinary telehealth. A bill that would set telehealth rules (A1782) is in committee, so whether a video-only visit can support a prescription is unsettled.
Virginia	Yes, unless the vet documents a medical reason and would not dispense the drug from their own practice either.	The exam can be done electronically. Federal rules still apply to off-label and human drugs.
Federal (all states)	No federal requirement.	Off-label use of drugs, including human drugs such as gabapentin or trazodone, needs a relationship that cannot be started by telemedicine alone (FDA).

Florida's 2026 law also says the acknowledgment form cannot include warnings about the safety or effectiveness of filling prescriptions at an outside pharmacy, and clinics must post a sign about the right at checkout. It does not apply to emergency dispensing or to restricted controlled substances.

Where a Video Vet Can Help, and Where It Can't

A video visit can help when the real problem is that you have no current vet relationship, or your clinic is booked for weeks, and your pet needs an FDA-approved animal medication used as labeled. It can also help you sort out a sick-pet question. It cannot replace a heartworm test, bloodwork or vaccines, and it is never the right choice in an emergency.

• Florida: a video-only visit can lead to at most a short, label-use course (14 days, or 1 month for flea-and-tick-only products) that cannot be renewed without an in-person exam. In our reading of the law, heartworm and combination preventives fall under the 14-day limit, so long-term prevention starts with an in-person test and exam.
• Virginia: the vet may establish care by video and decides case by case what is safe to prescribe, but federal rules still require an in-person relationship for off-label use or human drugs.
• New York: a vet can generally give advice and follow-up care by video, but whether a first video visit can support a new prescription is unsettled.
• Chewy's own vet service: Chewy's Connect with a Vet offers free chat with veterinary technicians in most states. Its video visits with veterinarians are currently available only in California, Indiana, New Jersey, New York, Ohio, Pennsylvania and Virginia, not Florida. Chewy's virtual-visit page says those vets may write a prescription after a video visit if needed; the free chat is with veterinary technicians, who cannot prescribe.

Any prescription is at the veterinarian's discretion, after they have assessed your pet.

How RexVet Can Help

RexVet is a 501(c)(3) nonprofit veterinary telehealth service with licensed vets for pets in Florida, New York and Virginia. If you have no current vet, or your clinic can't see your pet soon, a RexVet vet can see your pet on live video, review the medication question, and tell you what can be done by video under your state's rules and what needs an in-person visit. If the vet prescribes, you can ask for the prescription to go to the pharmacy you choose. In Florida, a prescription after a video-only visit is a short course that can't be renewed, so it won't cover long-term Autoship. A live video visit is $64.99, and the Family Plan is a one-time $120 for four visits over 12 months, no subscription. Book a video visit, or read how prescriptions from a RexVet vet work.

Frequently Asked Questions

How long does Chewy take to approve a prescription?

When Chewy contacts your vet directly, approval typically takes 1 to 2 business days, and pharmacist review usually takes less than 24 hours after that. Most customers receive prescription items within 3 to 5 business days once the vet approves. A mailed original takes longer, because the clock starts when it arrives.

Can I send Chewy a photo or scan of my pet's prescription?

No. Chewy says it can't accept photos, scans or photocopies from pet owners. Mail the original, or choose "Chewy contacts vet" at checkout if your clinic works with Chewy. For prescription diets, Chewy does let you upload a copy of an existing authorization.

What does "Declined" mean on my Chewy order?

Your veterinarian did not approve the prescription, and Chewy has canceled that order. Chewy suggests contacting your vet to find out why before you place a new order. Common reasons include an overdue exam, a needed heartworm test or bloodwork, or a medication the vet does not think is right for your pet.

Can my vet refuse to approve a Chewy prescription?

Yes. A refill request is at the attending vet's discretion, and a vet may decline for medical reasons. If your pet is current and the drug is medically appropriate, Florida and Virginia law generally give you the right to a written prescription you can fill at the pharmacy of your choice (in Florida, ask before the drug is dispensed; in Virginia, the vet may decline for a documented medical reason). New York's practice guidelines call for the same when a valid vet-client-patient relationship exists.

Do I need a prescription for heartworm prevention from Chewy?

Yes. Every heartworm preventive needs authorization from a licensed vet with a valid relationship with your pet. The American Heartworm Society recommends testing dogs 7 months and older before starting or switching prevention and every year after that; puppies under 7 months can start without a test.

Can Chewy's Connect with a Vet write a prescription?

Chewy's virtual-visit page says a vet may write a prescription after a video visit if needed. Those video visits are currently offered only in California, Indiana, New Jersey, New York, Ohio, Pennsylvania and Virginia. Elsewhere the free chat is with veterinary technicians, who cannot diagnose or prescribe. Check Chewy for current details.

Can an online vet in Florida, New York or Virginia approve my Chewy order?

Sometimes, within state law and only at the vet's discretion. In Florida a vet who has only seen your pet by video can prescribe FDA-approved animal drugs as labeled for up to 14 days (1 month for flea-and-tick-only products), with no renewals, human drugs or controlled substances. In Virginia a vet can examine your pet by video and prescribe when they judge it safe, though federal rules still require an in-person relationship for off-label and human drugs. In New York it is unsettled. Heartworm tests and bloodwork always require an in-person visit.
