For best protection
Part your dog’s fur at the base of the neck, in front of the shoulder blades, until the skin is visible. Place the tip of the pipette on the skin and squeeze to empty the contents completely.
Do not bathe your dog or allow swimming for 2 days after application, and do not apply more than once a week.
For optimal protection, apply FRONTLINE SPOT ON every 4 weeks to protect against fleas and ticks.
Always consider your pet’s lifestyle: dogs that go outdoors or visit areas with wildlife (such as foxes or hedgehogs) are at higher risk of picking up fleas and ticks than dogs that stay indoors.

Yes. POM-V items require a valid prescription from your UK vet.
Upload your prescription during checkout.
Photos must be clear. If details are wrong or expired, orders can’t be processed. This is standard across UK pet pharmacies.
No. Under UK law, vets must provide a written prescription if you request one for a POM-V medicine. They may charge a reasonable fee for issuing it, but they cannot refuse. This allows you to choose where to buy your pet’s medication, whether directly from your vet or from a registered UK pharmacy such as Ashcroft 4 Pets.
In the UK, most POM-V prescriptions are valid for 6 months, unless your vet specifies a shorter duration. Prescriptions for Schedule 2 or 3 controlled medicines are usually valid for 28 days and are not repeatable. At Ashcroft 4 Pets, we follow these same UK veterinary guidelines to ensure your pet’s medication is dispensed safely and legally.
At Ashcroft 4 Pets, we are a fully VMD-registered and accredited online retailer. This means every prescription and over-the-counter pet medicine we supply is safe, genuine, and dispensed according to UK law.

In the UK, most repeat prescriptions for POM-V medicines are valid for up to 6 months from the date your vet issues them. You can order multiple times within this period if your vet has authorised repeats.
For controlled medicines (Schedule 2 or 3), the prescription is valid for 28 days only and cannot be repeated. These medicines are strictly regulated due to their potential for misuse.
At Ashcroft 4 Pets, we follow UK law carefully, ensuring all prescriptions are dispensed safely, legally, and in the exact amounts prescribed.
If your vet prescribes a human medicine for your pet under the Cascade, we can usually dispense against that prescription (with the right checks).
