Chews, topicals, or collars? A vet-informed walkthrough of every flea and tick option so you can protect your dog year-round without overpaying.
Why year-round protection matters
Fleas and ticks aren't just a summer nuisance — they transmit tapeworm, Lyme disease, and other illnesses, and a single missed month can undo a whole season of protection. The good news: modern preventives are safe, effective, and easier than ever to give.
The three main options
Oral chews like NexGard start killing fleas within hours and can't wash off — ideal for dogs who swim or get bathed often.
Topicals such as Frontline Plus spread through the skin's oil layer and are budget-friendly, though they need 24 hours to become waterproof.
Collars like Seresto deliver up to 8 months of protection from a single application — perfect if you tend to forget the monthly dose.
How to choose
Match the format to your dog's lifestyle and your routine. Swimmers and forgetful households do best with chews or collars; multi-pet homes often save most with topicals.

Frequently asked
- Do indoor dogs need flea and tick prevention?
- Yes. Fleas hitch rides on shoes and other pets, and ticks can appear in yards and even high-rise balconies. Year-round prevention is recommended for indoor dogs too.
- Can I use a chew and a collar at the same time?
- Usually you should pick one primary preventive. Doubling up can be unnecessary and costly — ask your vet before combining products.
