Seresto Collar price comparison
Seresto is an over-the-counter flea and tick collar for dogs that works for up to 8 months. Because one collar replaces 8 monthly doses, we show cost per month. Counterfeit Seresto collars are a real problem on marketplace sites, which makes buying from an authorized retailer worth a small premium.

Why the same box costs so much more at the vet
Vet clinics buy medications in small quantities and price them with a margin that helps keep the practice running. That is not a scam, but it does mean paying 2 to 3 times the online price for the identical product is common.
Large online pharmacies buy in volume and compete with each other in public, which pushes prices down. Promotions move prices around too: first-order coupons and autoship discounts can shift the effective price by 5 to 30 percent, so we list base prices and note promotions separately instead of mixing them together.
Seresto Collar is sold over the counter, which means more retailers carry it and prices swing more often. It also means counterfeit risk on marketplace listings from unknown third-party sellers, so we only compare retailers selling through their own storefronts.
Common questions
How do I avoid counterfeit Seresto collars?
Buy from authorized retailers rather than third-party marketplace sellers. Counterfeits are widely reported on marketplace listings, often at prices that look too good to be true. Every retailer we compare sells through its own storefront.
Why is Seresto sold without a prescription?
Its active ingredients are EPA-regulated pesticides rather than FDA-regulated drugs, so it is sold over the counter like most collars and topicals.
Does Seresto protect against heartworm?
No. Seresto covers fleas and ticks only. Heartworm prevention requires a separate product. Ask your vet what your dog needs.
