It can be quite overwhelming for pet parents to choose the right flea and tick treatment for dogs among hundreds of options. You’ve probably noticed that the options don’t all work the same way. Some target fleas only others add ticks, mosquitoes, or heartworm prevention into the mix and they have different durations and active ingredients. The most important thing to consider is which parasites your dog actually needs protection against. This blog covers five of the popular topical flea and tick products for dogs, what’s actually in them, and how to think through the choice for your own dog.

What Is a Topical Flea and Tick Treatment for Dogs?

A topical, or “spot-on,” treatment is a liquid product applied directly to a dog’s skin, usually between the shoulder blades, at the base of the neck, or along the entire back from the base of the neck to the tail, where it can’t easily be licked off. These liquid products come in applicators that contain active ingredients to protect your dog for up to 30 days or longer, depending on the product.

How Do Topical Flea and Tick Treatments for Dogs Work?

After application, the active ingredients work according to the product’s specific mechanism to provide protection beyond the application site. Depending on the product, topical treatments either kill parasites on contact, or kill them once the parasites bite the treated dog and ingest the ingredients in the treatment.

Benefits of Using Topical Flea and Tick Treatments

Many topical products are applied using a single-dose applicator, making the dosage administration convenient. However, dosing frequency varies by product.
Topical flea and tick preventatives may be a convenient option for pets that are picky eaters or have sensitive stomachs.
Many topical also target the flea life cycle, and not just adult fleas, by using ingredients that stop eggs and larvae from developing, thus helping prevent flea re-infestations.
Some offer repellent activity against ticks or mosquitoes in addition to killing them, and a few extend coverage to other parasites like lice, ear mites, or heartworm. Not every topical does all of this, though. Coverage varies significantly by product.
Some topical treatments are water-resistant, making them a suitable option for dogs who like to swim.
