Do Flea Shampoos Work on Dogs?

Do Flea Shampoos Work on Dogs

Yes, the flea shampoo for dogs works. However, the exact effectiveness of flea shampoos varies between brands and is based on the active ingredient used.

Some flea shampoos control the multiplication of fleas, others will kill fleas but not eggs, and there is the flea shampoo for dogs that does everything – kills adult fleas and flea eggs while preventing further infestation.

To truly get rid of fleas on your dog, you will need to combine the flea shampoo for dogs with other flea treatments like oral medications, collars, or topicals.

How Long Does Flea Shampoo Keep Fleas Away?

Most shampoos can protect your dog from fleas for about a week. The time the flea shampoo for dogs is able to keep fleas away from your pet depends on its potency and active ingredient.

For optimal treatment and flea prevention, pair flea shampoo with other flea control methods such as deep cleaning and flea medication.

What Should I Look for When Buying Flea Shampoo for Dogs?

What Should I Look for When Buying Flea Shampoo for Dogs

When choosing a flea shampoo for dogs, ensure to check for the following features:

  • Acting Mechanism. Carefully read the instructions included on the packaging of the shampoo to ensure that you have the right resources to make the product work. For example, some brands may require multiple washes a week to work, and you may not have the time to do this.
  • Effectiveness. Know the capabilities of the shampoo you are using. Some shampoos only get rid of grown ticks and nothing else, while others can get the eggs, larvae, and grown ticks. Understand what your shampoo does to make certain that it matches your expectations.
  • Ingredients. Like with all pet products, you must thoroughly inspect the ingredients list of any shampoo to make sure it doesn’t contain any harmful ingredients such as sulfates, parabens, and MEA.
  • The Dog’s Coat. Ensure that the shampoo you choose is suitable for your dog’s breed characteristics. For example, long-haired dogs need shampoos that lather easily, or you will need a lot of product per wash to get your dog clean.

How Do You Make Natural Flea Shampoo for Dogs?

You can make a natural flea shampoo for dogs using simple, household ingredients in a few steps.


  • 1/2 cup of baby shampoo
  • 1/2 cup of water
  • 1/2 cup of lemon juice
  • Essential oils (optional)


  • To make the flea shampoo for dogs, simply mix the ingredients and pour them into a bottle. Use the shampoo as you would traditional store-bought shampoo.
  • If you would love to give your flea shampoo for dogs a pleasant smell, you can add pet-safe essential oils such as lavender oil, chamomile oil, and cedarwood oil.

Homemade, dog natural flea killers are especially helpful if your pet is prone to allergies and has sensitive skin. However, the DIY flea shampoo for dogs is not as potent as regular flea shampoos.

Does Dawn Soap Kill Fleas?

Yes, Dawn soap kills fleas. However, it doesn’t prevent future infestations.

If you wash a dog with fleas using Dawn soap, the adult fleas will die off, but new ones will hatch in approximately a week.

This is because Dawn soap does not kill flea eggs. Another reason Dawn soap is not good as a sole flea treatment is that it does not kill fleas in the dog’s environment. In other words, the dog can pick up new fleas from the surroundings immediately after being bathed.
