Dog Flea Shampoo Buying Guide

Do you hate to see your dog scratch and growl in pain due to a flea attack? It is important that you get a well-made and affordable shampoo for them. These are the crucial guidelines you need to pay attention to.

First things first – you should never ever use shampoos made for people on dogs. Human-use shampoos contain harsh chemicals that might negatively affect your furry friend's skin condition. Please keep the following points in mind so you can make an informed choice always.


No matter how hyped up or well-packaged a dog shampoo is, the most important thing is that it’s effective. Otherwise, if it doesn’t succeed at killing the fleas and keeping them away, it’s not worth it.

Online reviews can be a great place to start when you’re looking for the best kind of information regarding the effectiveness of a product. If other dog parents complain about a certain product, chances are that it will disappoint you as well.

Luckily, for you, our top products in this list have some pretty awesome reviews on Amazon. So, you won’t need to gamble with their effectiveness.


No matter what, you should never overlook the ingredients of your product of choice. Ingredients can make or break a product.

The first thing you need to consider is whether or not your dog is allergic to any of the ingredients in the product. In fact, to completely avoid skin allergies, we’d recommend going for shampoos that contain soothing ingredients such as the following:

  • Vitamin E
  • Honey
  • Rosemary
  • Chamomile
  • Tea tree oil

You can always consult your dog’s medical records or your vet to determine which particular chemical substances your pooch might be allergic to. That way, you can completely avoid them. Otherwise, you can use the trial and error approach until you identify a shampoo that works for you.


Dog shampoos are scented just as human ones are. So, in that case, you want to consider the kind of scent you like (or the one your dog likes if they have preferences). Either way, you don’t want to have your pup smelling like a trash can.

At the same time, you want to keep in mind the fact that some scents can cause a myriad of problems to dogs with sensitive skin conditions. So, if your dog has delicate skin, you want to be careful not to use a shampoo that’s too scented.

So, start small and let your dog gradually adapt. This way, you’ll be able to make choices that work for (and not against) them.

Frequently Asked Questions

Matters to do with dog shampoo are quite sensitive. To ensure that you never have to gamble with your choices, here’s our exclusive response to burning questions.

My dog has skin allergies, what do I need to know before buying a shampoo?

It is important to understand that no product in this world fully qualifies to be ranked as wholly non-allergenic. So, the best thing to do is to try and understand which specific ingredients your pet is allergic to. Look out for those in the list of ingredients before making a purchase.

Can I use dog shampoo on my cat?

Dogs and cats have an almost similar skin pH. So, the two pets can share one shampoo. However, both have different skin pH to that of human beings and should, therefore, not use products meant for humans.

What is the ideal frequency of shampooing a dog?

The frequency for applying a flea shampoo varies depending on the size of your dog’s coat, whether it has sensitive skin or not and also the type of coat. Also, if your K9 spends long hours outdoors, you might want to bathe him more often. But on average, it’s okay to bath your dog at least once per month.

Which One Is The Best?

We have carried out in-depth reviews of different kinds of dog flea shampoos. If we were to choose just one that’s probably the best, we’d settle for the Hartz UltraGuard Flea & Ticks Shampoo. We like its overall quality, scent, and packaging as well.

That said, we’d like to reiterate that there’s nothing like a perfect shampoo product. So, you might want to do a bit of try and error analysis until you find just the perfect product for your pooch.

Final Thoughts

It’s only human to want to take good care for your pet. One way to do that is by ensuring that no fleas get underneath their fur and start reproducing. The best way to bring that to an end is by making good use of the best dog flea shampoo in line with the recommendations made above.
