Is buying dog medication online cheaper than the vet?

Yes, materially. The CMA estimates over 200 pounds per year typical saving. Senior dogs on multiple chronic medications save 600 to 900 pounds per year in our internal data, after the 21 pound prescription fee.

Do I need a different prescription for each online pharmacy?

No. One written prescription is valid at any VMD approved pharmacy for six months. You can shop the cheapest each refill if you want.

What happens if my vet refuses to give me a written prescription?

Before 23 September 2026, the RCVS Code of Conduct recommends it as best practice but is not strictly enforced. After 23 September 2026, your vet is legally required to provide one on request, capped at 21 pounds. If a practice refuses post September 2026, the RCVS complaints process is one option, switching practice is another.

Are foreign online pharmacies (EU or US) safe?

For UK pets, no. UK regulation (VMD) is specific to UK approved retailers. Even if a foreign pharmacy is reputable in its home market, it is not subject to UK inspection and the medication may not be the UK authorised version. Buying foreign medication for your UK dog also creates a legal grey area if anything goes wrong.

What if a pharmacy is on the VMD register but my vet still says not to use it?

You can use any VMD approved pharmacy. Your vet can decline to write the prescription based on clinical judgement (e.g. they want to assess your dog first), but they cannot validly object to which approved pharmacy you choose to fulfil it at.

Can I get the same brand my vet uses?

Yes. All UK approved pharmacies dispense the original manufacturer brand (Apoquel from Zoetis, Vetmedin from Boehringer, Cytopoint from Zoetis, Bravecto from MSD, etc) in original blister packs and bottles. The supply chain origin is the same.

Are UK online pet pharmacies safe? How to check (and which six we trust)

Yes, UK online pet pharmacies are safe to buy from, provided the pharmacy is on the Veterinary Medicines Directorate's register of approved internet retailers. This single check (which takes 30 seconds at gov.uk) separates the legitimate UK regulated channel from the foreign or unlicensed sites that should be avoided. Here is how the VMD approval works, how to spot a fake, and the six UK pharmacies we currently link to.

Key takeaways

The VMD register is public and free at gov.uk/check-veterinary-medicine-seller. Look up any UK online pharmacy by name in 30 seconds.
The green VMD logo must click through to the pharmacy's own entry on gov.uk. Logos that do not resolve back to the register are the single biggest red flag.
Six pharmacies we currently track (Animed Direct, Pet Drugs Online, VetUK, Hyperdrug, PetMeds / Express Chemist, Chemist.co.uk) are all on the register and dispense the same Zoetis, Boehringer, MSD and Elanco manufactured drugs as your vet.
Five red flags for unlicensed sites: no UK address, no working VMD logo, prescription only medication available without a written prescription, generic packaging, "shipped from EU or outside UK".
All you need to buy POM V medication is a written prescription from a UK qualified vet, capped at £21 from 23 September 2026 (plus £12.5 per additional medicine on the same prescription).

How does VMD approval actually work?

The Veterinary Medicines Directorate is the UK government regulator for veterinary medicine. It is part of Defra. Its job is to authorise veterinary medicinal products, license manufacturers and wholesalers, and inspect everyone who sells veterinary medicine to UK pet owners. That includes high street retailers, vet practice dispensaries, and online pharmacies.

For an online pharmacy to dispense prescription only medication (POM V, which covers Apoquel, Vetmedin, Cytopoint, Bravecto, all the chronic medication we cover) to UK customers, it must:

Register with the VMD as an approved internet retailer. The application is rigorous and includes site inspections.
Employ a registered Suitably Qualified Person (SQP) or veterinary surgeon to oversee dispensing.
Operate from a physical UK premises that has been inspected and approved by the VMD.
Submit to ongoing inspections on the same cycle as a high street human pharmacy.
Verify each prescription against a written prescription from a UK qualified vet before dispensing.
Comply with controlled drug regulations (Home Office register keeping, secure storage, double signed dispensing for relevant drugs).
Display the green VMD logo on the website with a unique accreditation number that links back to the VMD's public register entry.

The register is public, searchable, and free at gov.uk/check-veterinary-medicine-seller. You can look up any UK online pharmacy by name and either find them (legitimate) or not find them (avoid).

What does the green VMD logo actually mean?

The green VMD logo, properly used, is a clickable link that resolves to the pharmacy's own entry on gov.uk's approved retailers register. Two things matter:

It must be the official green VMD logo with an accreditation number. Some unlicensed sites use a fake "approved" badge that looks similar. Check the colour (it is a specific official green) and the number (it should be a 4 to 6 digit identifier).
The logo must link back to gov.uk. Click it. If it links to the pharmacy's own About page, that is not the official scheme. If it links to gov.uk/check-veterinary-medicine-seller/SELLER-NAME, that is the real thing.

Cross checking against the gov.uk register is the single most reliable thing you can do. Bookmark it. It takes 30 seconds.

The six UK pharmacies we currently link to

All six are on the VMD register. All six dispense the same manufacturer branded medication as your vet practice. We refresh pricing across all six monthly (first weekend of every month) and feature whichever is cheapest for each medication on the relevant medication page.

Animed Direct

Family run UK pharmacy specialising in pet medication. Long established, large catalogue, generally competitive on monthly chronic medication. VMD approval number visible on their site, links back to gov.uk.

Pet Drugs Online

Family owned, one of the longest established UK pet pharmacies. Strong on parasiticide (Bravecto, NexGard, Frontline) where they are frequently the cheapest in our weekly data. VMD approval visible, register link works.

VetUK

UK based, broad catalogue including specialist diets and supplements alongside prescription medication. Generally mid market on price.

Hyperdrug

Family run, competitive on bulk packs. Smaller catalogue but strong on the medication we cover most. VMD approval valid.

PetMeds (Express Chemist)

Part of a wider human pharmacy group with a pet medication arm. Trustworthy provenance, sometimes slower fulfilment than the dedicated pet pharmacies. VMD approval valid.

Chemist.co.uk

Broad pharmacy retailer with a pet medication category. Less specialised than the dedicated pet pharmacies but legitimate and competitively priced on some lines. VMD approval valid.

All six display the green VMD logo on their homepage. Click it. The link should resolve to gov.uk/check-veterinary-medicine-seller. If it does not, do not buy from that site (even if they look identical to a legitimate one).

What about Amazon, eBay, or general marketplace sellers?

Avoid them for prescription medication. The marketplace model means individual sellers, who may or may not be VMD approved, list product. Even if the pharmacy fulfilling the order is on the register, the marketplace listing itself often does not comply with VMD rules on prescription verification. You may receive what looks like genuine medication but with no audit trail.

The exception is non prescription items (collars, food, basic supplements). These are not regulated as veterinary medicines and you can buy them anywhere. Anything labelled POM V, POM VPS, or NFA VPS should come from a VMD approved retailer.

How do I spot a fake site?

Five red flags. Any one of them should kill the order.

No UK address. The pharmacy must have a physical UK address listed in the website footer. Foreign addresses, PO boxes only, or no address at all are immediate disqualifiers.
No VMD logo, or a logo that does not link to gov.uk. A real pharmacy displays the logo prominently and the link works. A fake site may display a "verified" badge that links nowhere or links to a self hosted page.
Prescription only medication available without a written prescription. If you can put Apoquel or Vetmedin in your cart and check out without uploading a prescription or having a vet email one in, the site is not VMD compliant. Walk away.
Generic, unbranded, or "compounded" packaging. UK approved pharmacies dispense in original manufacturer packaging (Zoetis, Boehringer, MSD, Elanco, etc). If the medication arrives in a plain bottle or "made up" packaging, it is not the same drug your vet dispenses.
Suspicious payment flow or domain. Recently registered domain, no SSL, foreign payment processor, or pressure to pay via wire transfer or crypto. Legitimate UK pharmacies use standard UK payment processors (Stripe, PayPal, Worldpay).

What if I have already bought from a site I am now not sure about?

If you have given medication from an unverified source to your dog already, contact your vet for guidance. The most likely outcomes are that the medication is fine, or that it is a counterfeit but not actively harmful, or in rare cases that it is harmful and the dog needs monitoring. Your vet can advise based on what your dog is on and what symptoms (if any) you have seen.

Going forward, only order from the gov.uk register. Bookmark the register and check every new pharmacy before placing your first order.

What does the prescription side look like in practice?

To buy POM V prescription medication from any UK approved online pharmacy, you need a written prescription from a UK qualified vet. The flow:

Email your vet asking for a written prescription for [medication name], [strength], [pack size]. Be specific.
From 23 September 2026, the fee is capped at £21 (plus £12.5 per additional medicine on the same prescription).
Bundle every chronic medicine onto one prescription if you can. You pay one main fee plus the additional medicine surcharge.
The prescription is valid for six months for most products (28 days for controlled drugs).
Upload or post the prescription to the online pharmacy. Most have a digital upload form.
The pharmacy verifies the prescription against the VMD's prescribing vet register and dispatches the medication, typically same day if ordered before 2pm.
Set up the refill cadence with the pharmacy if it is a chronic medication. Most send a refill prompt with a click to reorder.
