Prescription Management & Refills

We provide prescription refills and ongoing medication support for pets with both short-term and chronic conditions. If your pet requires long-term medication, we will work with you to monitor their progress and make any necessary adjustments.

Additional Pharmacy Support

For medications not stocked in-house or for specialized treatments, we can provide written prescriptions for you to fill medications through trusted external pharmacies, to ensure your pet has access to what they need.

Our goal is to make managing your pet’s medications as simple and seamless as possible, while ensuring their safety and well-being.

Frequently Asked Questions About Our Veterinary Pharmacy

Why should I buy medications directly from your in-house pharmacy instead of an online retailer?

When you use our on-site pharmacy, your pet’s medications are backed by a direct manufacturer guarantee. This ensures they have been shipped, stored, and temperature-controlled under strict regulatory guidelines. Furthermore, our veterinary team double-checks every dosage against your pet’s exact weight and medical history to prevent drug interactions.

Can I get a written prescription to fill my pet's medication at a human pharmacy?

Yes. If your pet is prescribed a medication that is also used in human medicine, we are happy to provide a written prescription upon request. However, please note that many specialized veterinary medications—such as specific pet-friendly antibiotics, flavored chewable heartworm preventatives, or liquid suspensions tailored for cats—are completely unique to veterinary medicine and can only be obtained through a licensed animal hospital.

Why does my pet need a physical exam or blood test before getting a prescription refill?

To safely refill medications, Ontario veterinary regulations require an active veterinary-client-patient relationship (VCPR). For short-term medications like antibiotics, an exam ensures the infection is actually gone. For long-term drugs (such as thyroid, heart, or arthritis medications), routine blood work is essential to make sure the dosage remains effective and isn’t causing unintended stress to your pet’s liver or kidneys.

How do I request a prescription refill for my pet, and how long does it take?

Requesting a refill is simple. You can call our Mississauga clinic directly or send us a request online. We ask that you give our pharmacy team 24 to 48 hours notice to process your request. This allows our veterinarians time to thoroughly review your pet’s medical record, confirm the correct dosage, and accurately prepare the medication for a safe pick-up.

What should I do if my pet refuses to take their pill or chewable medication?

You are not alone—getting pets to take medication can be a real challenge! Let our team know right away if you are struggling. We can offer helpful demonstrations, provide specialized pill-masking treats, or explore alternative options. In many cases, we can work with compounding pharmacies to transform a bitter tablet into a tasty, flavored liquid (like chicken or tuna) or a topical gel that is easily rubbed inside your pet’s ear.
