Online pet pharmacies have revolutionized how pet owners buy medications — often saving 30–60% compared to vet clinic prices. With auto-ship programs, free shipping, and price-match guarantees, buying pet medications online is the cheapest option for most prescriptions. But you'll still need a written prescription from your vet for any Rx medications.
Using an online pet pharmacy can save the average pet owner $200–$600 per year compared to buying medications at the vet clinic.

How to Save the Most Money
- Get a written prescription from your vet: Your vet is legally required to provide one if you ask. You don't have to buy from them.
- Use GoodRx at human pharmacies: For generic human meds used in pets (Gabapentin, Fluoxetine, Tramadol, Doxycycline, Phenobarbital) — 50–70% cheaper than vet prices.
- Set up auto-ship: Chewy saves 35% on the first order and 5% ongoing. Never run out of preventive medications.
- Compare prices before buying: Check Chewy, 1-800-PetMeds, and GoodRx — prices vary by medication.
- Buy 6–12 month supplies: Heartworm and flea/tick preventives are cheaper per dose in bulk. Manufacturer rebates often require 12-month purchase.
- Ask about generic equivalents: Many brand-name pet meds have generic equivalents that are 50% cheaper with the same active ingredient.
- Check manufacturer rebates: Zoetis (Simparica Trio, Apoquel), Elanco (Trifexis, Interceptor), Boehringer Ingelheim (NexGard, Heartgard) all offer seasonal rebates.
