Don’t worry about asking your vet to write you a prescription. They have an obligation to help you get your pet’s medication in the way that’s cheapest and most convenient for you.
Shop around. Some online pet drug retailers are cheaper than others.
Check that your chosen pharmacy is Veterinary Medicines Directorate Approved and a member of the Royal College of Veterinary Surgeons – look for the VMD Accredited Retailer badge on their site.
It’s worry-free. A pharmacist will check your order and prescription – you can’t order the wrong drug or dosage.
