Common Questions

What should I know about pet health brands?

Every brand at PetMeds is sourced direct from the manufacturer or their authorized distributor. Prescription brands require a valid prescription from your vet, while OTC brands like Frontline and Greenies can be purchased without one. PetMeds carries more than 500 brands across every major category of pet health.

Yes. Every product we sell is sourced directly from the manufacturer or their authorized distributor. We are a licensed pharmacy and we never buy from third-party marketplaces or unverified sellers. If it says PetMeds on the label, it came from the brand itself.

It depends on your dog's size, age, lifestyle, and flea or tick risks in your region. NexGard and Bravecto are the two most popular chewable options. Frontline and K9 Advantix are the most popular topicals. Call our pharmacists at 1-800-738-6337 — they'll help you pick the right one for your dog's situation, at no charge.

For prescription brands, yes — but you'll need a new prescription. Call your vet and ask them to send a prescription for the new medication to us, or we can reach out to them on your behalf. For over-the-counter brands like Frontline or Greenies, you can switch anytime without involving your vet.

Yes, where generics exist and are FDA-approved for veterinary use, we carry them — usually at 20–40% lower cost than the brand-name equivalent. Ask your vet whether a generic is appropriate for your pet. Our pharmacists can also tell you on a call whether a generic substitute exists.

Call your veterinarian immediately if your pet shows signs of an adverse reaction. You can also call us at 1-800-738-6337 and a pharmacist will talk through what you're seeing. We report all adverse events to the manufacturer and the FDA. If the reaction is confirmed, we'll work with you and your vet to switch to a different brand or formula.

PetMeds carries more than 500 pet health brands spanning every major category — flea and tick prevention, heartworm medication, prescription therapies, prescription and non-prescription diets, supplements, dental products, and more. Use the filter above to narrow by pet type, condition, or price.
