10 Best Flea And Tick Dog Shampoos 2026 in the United States

The ADAMS Plus Flea & Tick Shampoo with Precor is a well-regarded option for treating flea and tick infestations in dogs and cats aged 12 weeks and older. Its active ingredient, coconut extract combined with Precor (an insect growth regulator), kills fleas, flea eggs, ticks, and lice on contact, while preventing new flea eggs from hatching for up to 28 days. This gives it a solid duration of effect compared to some shampoos that only kill adult pests. It’s suitable for all sizes and life stages over 3 months, which adds safety and convenience for most pet owners.

Beyond pest control, it also cleans and conditions the coat, leaving pets’ fur soft, shiny, and manageable. The shampoo has a light, fresh scent that most users find pleasant without being overpowering. In terms of ease of use, the shampoo is concentrated, so only a small amount (about 4 teaspoons per 5 pounds of pet weight) is needed, which can make the bottle last longer.

Some potential downsides include the need to wait until pets are at least 12 weeks old, so it’s not suitable for very young puppies or kittens. Also, as with any medicated shampoo, it requires bathing and rinsing your pet fully, which might be a challenge for some pets. Additionally, while it has a good reputation and many positive reviews, the actual application only treats pests present at the time of the bath and won’t provide long-term protection by itself without repeat use or complementary products. This shampoo is a strong choice for dog and cat owners looking for an effective, multi-action flea and tick shampoo that also cares for the coat and is easy to use. It’s particularly good for pets over 12 weeks old who need a trusted, light-scented product that offers a month-long effect against pest eggs and adults.

The ADAMS Plus Botanicals Flea & Tick Shampoo is designed to treat flea and tick infestations on dogs and cats, including puppies and kittens, making it a versatile option for pet owners with multiple pets or young animals. Its active ingredient, Precor, targets fleas and lice, including their eggs, helping to break the infestation cycle. This not only kills pests present but also reduces future re-infestations. The shampoo is plant-based, which may be gentler on pets' skin compared to harsh chemical treatments, and it cleans and conditions the coat, improving the look and feel of your pet’s fur. It’s safe for all life stages, so there are no age restrictions.

Users have rated it highly, suggesting it’s effective and well-liked, but as a shampoo, it requires regular bathing, which some pets may not enjoy or tolerate easily. In terms of ease of use, it comes in a convenient 16-ounce bottle, which should be enough for multiple uses depending on your pet’s size. This shampoo works well as part of a broader flea and tick control plan but may not be sufficient alone for severe infestations.

This shampoo is a solid choice for pet owners looking for a botanical, multi-pet option that cleans and conditions while helping control pests.

The Adams Plus Flea & Tick Shampoo with Precor is a versatile solution for dogs and cats over 12 weeks old. It effectively kills adult fleas, flea eggs, ticks, and lice, making it a comprehensive treatment option. The inclusion of Precor, an Insect Growth Regulator, means it provides lasting protection by preventing flea reinfestation for up to 28 days. This can be particularly reassuring for pet owners looking for a long-term solution.

It's formulated with soothing ingredients like aloe vera, lanolin, coconut extract, and oatmeal, making it suitable for pets with sensitive skin. After use, it leaves your pet's coat soft, shiny, and with a pleasant fresh scent, which can be appealing for those who enjoy a well-groomed and nice-smelling pet. Additionally, the shampoo is economical since a little goes a long way, requiring only about 1⅓ tablespoons per 5 lbs of pet weight.

However, it's important to note that this product should not be used on pets younger than 12 weeks. The application process requires a thorough lathering and a 3 to 5-minute wait before rinsing, which might be a bit time-consuming for some pet owners. This shampoo is well-suited for pet owners seeking a reliable and gentle flea and tick solution with added skin and coat benefits.
