What prescription dog flea and tick treatment is best?

The difference between over-the-counter and prescription flea and tick medication is that you need a vet to prescribe the latter. The ingredients in prescription medications are more carefully controlled and regulated, and therefore, dosing may be more precise and possibly safer. Many prescription treatments are more effective than over the counter products, as well. Your vet can give you the most up-to-date information on what works well, what’s safest and what’s right for your pup.

What is the difference between over-the-counter and prescription dog flea and tick medication?

Dog flea treatments work in different ways depending on which product you use. Prescription oral and topical flea treatments usually work by depositing chemicals into the sebaceous glands of your dog. These chemicals then spread out over the body as your dog’s coat lubricates itself, neutralizing fleas and ticks by acting on their central nervous system. This prevents them from feeding on your pup and causing irritation, itch, parasites and disease.

To set up Autoship for your prescription dog medicine, select the Autoship option at checkout and choose how often you want it delivered. Once you set up Autoship, you can cancel or change your deliveries any time you want. You must have a valid prescription or remaining refills on file for Autoship pharmacy deliveries to occur. If we do not have a prescription, or if your prescription is expiring soon, one of our team members will reach out to your vet to obtain all the necessary information. You’ll always have your prescription dog medicines on hand when you choose Autoship from Chewy!
