It’s natural for dogs to have the occasional itch, but when it persists, pet owners may wonder whether their canine has a case of fleas.

 For dog owners and their pup, fleas are easy to contract and can be tricky to eradicate. That is why we have compiled a guide to the best flea and tick treatment for dogs.

Throughout the guide, we will take a closer look at the different types of treatments that kill fleas and the products available for pets that can help with flea prevention. 

The Best Dog Flea & Tick Medications Summary

Types of Flea Control Products

The pet market offers various flea control products, and each has its pros and cons. Here are the different types of anti-flea products:

  • Topical treatments popularly called spot-on products are excellent choices for killing fleas and preventing flea infestations. They are applied directly to the skin and usually last about 30 days. However, they can cause skin irritation in some pets and are not suited for dogs that are frequently exposed to water. 
  • Oral medications also known as flea pills, are given by mouth and are highly efficient. Some pills have lasting effects of up to several months, while others need to be given as frequently as every day. 
  • Flea Collars as suggested by the name, flea collars are worn around the neck. They are usually efficient for several months, thus making the ideal choice for owners who dislike monthly treatment renewals. However, not all dogs are willing to wear a collar 24/7.  
  • Flea Shampoos are efficient in killing the fleas that are currently inhabiting your dog‘s fur. However, once the bath is over, they have no residual effect meaning your dog is once again susceptible to flea infestations. For lasting effects, you can use flea shampoos in combination with other preventives. 
  • Flea Sprays need to be applied on the skin and fur. They used to be popular in the past, but today they are rarely used. This is because flea sprays are harder to use than most treatments and do not have residual efficacy.

How We Selected the Best Flea and Tick Treatments for Dogs

To compile this list, we have reviewed dozens of different products. These are the main factors we considered when selecting the best flea and tick treatments for dogs: 

  • Quality: The first thing we considered when reviewing the products in this article was their quality. A high-quality pest preventive needs to act quickly while being 100% safe for your pet. Quality usually comes at a price, but there is no room for negotiations regarding your dog’s health. 
  • Effectiveness: By effectiveness, we mean the product needs to successfully kill a larger number of pests in a relatively short time frame. Ideally, the product will be effective against different parasitic life stages. For example, it will kill adult fleas, flea larvae, and flea eggs. 
  • FDA and EPA-approved: The only way to ensure the product is efficient and safe for you, your dog, and the environment is to have approval from the Food and Drug Administration (FDA) and the Environmental Protection Agency (EPA).  
  • Delivery Method: Some treatments are applied topical, others are given in the form of edible treats, and some need to be worn as collars. Some pet owners find certain delivery methods more straightforward than others. 
  • Range of Efficacy: Depends on the type of active ingredient used in the product. Some active ingredients are powerful against fleas and ticks, while others protect from additional parasites like lice, mosquitoes, and flies. The type of active ingredient also determines the longevity of the product’s residual activity. 
  • Ease of Use: Considering the frequency of using the preventive, it is simpler to choose a product that is easy to administer and readily available (Amazon, Chewy). Products that require wearing gloves during the application or keeping your dog away from cats or children after use are considered hard to use. 

What to Look For in Best Flea and Tick Treatment for Dogs

As you can see, there is a wide array of flea control products for dogs different types, different brands, and different methods of use.  

Since not all products are made the same, finding the right one can be tricky. To make the shopping process simpler, we have compiled a checklist of the things you need to look for in a flea & tick treatment:

  • Prescription vs. Over-the-Counter: For some treatments, you will have to visit the vet’s office and get a prescription, while others are easily available over-the-counter. 
  • Using Preventatives Year-Round: All preventives need to be used all year round, meaning you will need to reapply the treatment as soon as its efficiency finishes. Some treatments have longer-lasting effects, while others need monthly renewals. 
  • Not all Products are Created the Same: Just because the product has a dog and a flea picture does not mean it is safe and efficient. Make sure you purchase the treatment from a reputable brand. 
  • When in Doubt, Consult your Veterinarian: If your pet suffers from a chronic condition or is on long-term medications, you should consult with your trusted vet before using a product for flea and tick prevention.  treatment. 
  • Some Products may be Used Together: It is also possible to combine different types of products. For example, a shampoo kills fleas immediately, and then a topical treatment can be applied for more lasting infestation prevention. 

What You Need to Know about Fleas and Ticks in Dogs

As a quick reminder, parasites can be classified into two groups:

  • Internal (roundworms, hookworms, tapeworms, heartworms)
  • External (fleas, ticks, lice, mosquitoes, flies)

When it comes to external parasites, fleas and ticks are the most widespread and imminent danger. 

According to Dr. Elizabeth Racine, “Fleas and ticks are not just pests – they also transmit harmful diseases, including diseases that can affect humans, like Lyme disease. Keeping these parasites off your pets and out of your home is essential to the health of your whole family.  Year-round flea and tick prevention, as recommended by your veterinarian, is the best way to ensure your pets are protected.”

Namely, fleas and ticks are dangerous on several levels:

  • Their mere presence causes irritation and inflammation of the skin that causes itchiness and can trigger secondary skin infections and hair loss.
  • They feed on blood and, if present in larger numbers or on smaller dogs, can cause anemia.
  • More often than not, they carry pathogens and are responsible for Lyme disease, Rocky Mountain spotted fever, ehrlichiosis, babesiosis, tick paralysis, etc. 

Managing flea and tick infestations is much more challenging than investing in a high-quality –  safe, and efficient prevention product.  

Our Final Thoughts on The Best Flea and Tick Treatment for Dogs
