Best Flea Shampoo For Dogs 2021 – Reviews & Buyer’s Guide

Just like us humans, animals, too, hate fleas on their body. It is not only irritating but can also cause severe itching in the long run. So, it’s necessary that you get the fleas out of your pet’s body.

If your dog has a long and thick haircoat, then the fleas can multiply and thrive in them forever. Thus, the only option left would be to groom your dog’s haircoat. However, the best flea shampoo for dogs can prevent the growth and protect your dog’s coat from further attacks of the fleas.

If you are looking for the best flea shampoo for dogs online, then you are in the right place. From the factors to consider while buying a dog flea shampoo to the best products in this category, we have got it all covered for you. Without much ado, let’s see some of the best flea shampoos for dogs available online.


Factors to look for when buying a Flea Dog Shampoo for Dogs

1. All-natural or synthetic

You can either buy all-natural, semi-natural, or synthetic shampoos for your dogs. All-natural shampoos don’t form lather with water. Thus, you need to take a good amount in your hand and then work it thoroughly over the dog’s body to cleanse and exfoliate it. However, these shampoos are the best and work like magic for dogs with sensitive skin or previous allergies.

Semi-natural shampoos do form some lather, and the ingredients may or may not have some added chemicals to enhance the color and fragrance of the product.

If you go for synthetic shampoos, the results will be visible in very few weeks, but you need to keep using it to maintain the results. However, such shampoos don’t treat the root cause. Instead, they focus on killing fleas and their eggs.

2. Skin type of your dog

The skin type and texture of your dog do matter, and you need to consider this when buying flea shampoo. Some dogs have extremely sensitive skin, and thus, their skin may not be able to tolerate parabens or sulfates that essentially form the lather.

Some dogs have dehydrated and flaky skin. Buying a shampoo that has a conditioning property can solve this problem. If your dog has dry skin, make sure that the shampoo has some kind of oil or aloe vera extracts in it. Oatmeal is another ingredient that doesn’t allow the shampoo to dry up your skin completely.

Dogs with skin allergies should consult a vet before roping a particular shampoo to treat fleas. Even if the shampoo says it is the best flea shampoo for dogs or can be used on dogs with skin allergies, you need to be double sure. If not, it can burn their skin and can even cause severe skin infections.

3. Length of the hair coat

The length of your pet’s hair coat does matter. This might sound weird. If your dog has a puffy or long hair coat, then you need to either buy a semi-synthetic or synthetic shampoo. Only then the effect of the shampoo will reach the interior of the thick hair coat.

If you insist on using an all-natural shampoo, then prepare to buy a huge container of it. As natural shampoos don’t form a lather, you will have to use quite an amount of the shampoo to deeply cleanse the hair coat.

4. Age of the dog

You can’t use any flea shampoo on your dog’s body just because the label says it’s the best flea shampoo for dogs. The age of your pet certainly matters. Most shampoos are meant for dogs above 12 weeks of age.

For dogs below the age of 12 weeks, you will have to find some home remedies to cure the flea problem.

5. Usage of the shampoo

The shampoos come in different forms. Some are meant for spot treatment, while others can be used as normal dog shampoos. Some flea shampoos come in the form of dips and others as sprays or leave-in shampoos.

To identify the type of flea shampoo that best fits your dog, you need to get them medically examined. Then the doctor will suggest which type of shampoo can bring a change in their condition.
