No one wants fleas taking over their sofa or jumping from their dog on to their bed.  Your friends probably think the same, which could stop them bringing their dogs over or choosing a different route when taking their pooch for a walk to avoid passing your front lawn.

However, all this can be avoided with proper treatment of fleas.

Top 3 Best Flea Shampoo Comparison

These are a few considerations to bear in mind when it comes to treating your dog for fleas.

Before diving straight into individual product reviews, we thought we would offer a general overview of the topic to start with. Beginning with why your dog gets fleas in the first place, whether they’re dangerous to you, your children and your dog as well as answering any other questions you may have.

Why do Dogs Get Fleas?

Why dog’s get fleas may still be a mystery to some dog owners.

You can clean your pet thoroughly, think you are applying the right products, and even take your dog to the vets for extra help only for fleas to return a week later jumping freely from your pet to your carpet and back again.

The annoying thing with fleas is that they could come from almost anywhere! 

When combating fleas sometimes you have to go further than just making sure your dog is clean, it may be that contact with other dog’s means fleas have a smooth passage back to your dog or that somehow fleas have infested your yard and even your home as well.

Not only could your yard be the culprit but other humans may also be unknown carriers, this may be the case if they have come in to contact with another animal with fleas earlier that day, allowed fleas on to their clothes which then jump on to your dog later on.

Although fleas don’t fly, they use their strong back legs to leap from unsuspecting carriers to your pet. This makes them a pesky enemy, but with the right help, you can win the battle.

How to Tell if Your Dog Has Fleas

Before buying and applying a specialist flea and tick shampoo to your pet you first need to establish that your dog has fleas.

In some cases, and particularly severe infestations it will pretty easy to spot fleas jumping and actively moving through your dog’s coat and off on to surrounding furniture.

One of the big telltale signs of a flea infestation will be your dog acting restlessly and either scratching or chewing at specific areas of their skin that are particular itchy or inflamed.

However, it is not always so straightforward to spot any unwanted flea or tick intruders.

Instead to tell if your dog has fleas you should inspect their skin and coat thoroughly looking out for a number of clues.

As already mentioned, in some cases the fleas themselves will be visible, but they can also be hard to spot. They move extremely fast and can jump very quickly so instead of trying to detect the fleas themselves you should also look out for:

  • Signs of scratching, redness or blood
  • Red and bumpy/pimple areas around your dog’s belly, groin or base of their tail
  • Flea dirt
  • Any bites or burrows that have been made on your dog’s skin
  • Flea eggs

These checks can be carried out visually, but you can also use other tools if you wish as well.

A fine-toothed flea comb can be handy when looking for fleas and any flea dirt left behind. By running the flea comb through your dog’s coat, you will be able to drag out any unwanted visitors with it.

Are Fleas Dangerous?

Firstly, fleas, on the whole, are not dangerous to humans. If you worried about an infestation in your home, it is something you should combat with the right products, but regarding your health, there is very little danger.

Flea bites may lead to some skin irritation but not enough for a major emergency.

The danger with fleas lies very much with your pet. 

For your dog fleas may lead to severe skin irritation and other diseases in extreme cases. Fleas can be extra trouble if your dog already has a history of skin irritation as the continual scratching to remove the fleas will only make the issue worst which can lead to long-lasting problems for your pet.

How Do Flea and Tick Shampoos Work?

Flea shampoo’s for dogs work by killing adult fleas with a combination of ingredients while at the same time thoroughly cleaning your pet.

This dual approach of washing your pet while at the same time combating these unwanted intruders makes flea shampoos an excellent solution for ridding your pet of flea and ticks.

However a word of warning, because of the effectiveness of this type of product, fleas can often be left floating in your bath after washing your dog with flea shampoo. This is obviously a good sign but can sometimes take new dog owners by surprise if they aren’t quite prepared for it.

The second word of warning is that it can be tough to stop fleas returning if you do not also treat your environment. Flea shampoo should be used in combination with many different approaches, some of which are discussed throughout this guide.

Are Flea Shampoos Safe?

Because of the nature of medicated flea shampoo’s, as pet owners, we have to be particularly careful about what ingredients we are treating our dogs with.

Shampoos that include chemical ingredients are obviously going to be the most effective in treating your pet for fleas. However, you also need to be aware of the long-lasting effect that these products may be having on your dog’s skin and coat.

One particular type of ingredient that has come in for criticism by many regulatory boards within the U.S. is the use of synthetic pyrethroids.

These should not be confused with pyrethrins, and the difference will be looked at now.

Ingredients to be Wary of  – Pyrethroids vs. Pyrethrins

Now bear with us with trying to pronounce the names of either of these chemicals.

The majority of flea-fighting products you will come in to contact with will contain either one of the two above.

Flea shampoos differ from other types of dog shampoos purely because they have been manufactured to do one thing very well: kill fleas.

This means that some manufacturers in the process have decided to neglect the health of dogs being treated in the process which completely defeats the object and is something we want to help you avoid.

The critical difference is that pyrethrins are natural extracts that from certain types of plants while pyrethroids have been designed to be more efficient and ultimately longer lasting but have come from a laboratory and aren’t found in nature.

Pyrethroids are often found in pest control products and affect the nervous system of certain types of insects, as a result making them a great flea repellent.

Because of this, when choosing the best flea shampoo for your dog, it is essential that you pick a product that is safe and ultimately won’t harm them.

To do this, we recommend carrying out additional research on the topic and to choose a shampoo that has been proven safe through testing.

We also advise you refer to the ingredients being used on the packaging of the flea shampoo you select and consult your vet if you are still unsure.

Treating Your Environment as well as Your Dog

One of the biggest annoyances we hear from pet owners suffering from fleas is that whatever they seem to do, whether it is using the best flea shampoo or applying the latest flea collars, these pesky intruders keep coming back time and time again.

Although this is annoying, luckily there is something you can be doing which up until this point you may have been overlooking and that is to treat your home for fleas as well as your dog.

To put it simply, it isn’t enough to buy one of the flea and tick shampoos reviewed below, treat your dog and in think you’re done.

Fleas bite quickly, and then lay eggs which scatter into the environment around your pet.  This environment can include your carpet, sofa or any bedding – both yours and your dogs.

Once nested these eggs then hatch and the cycle of infestation begins.

This means even if you manage to kill every flea lurking on your dog, they will be covered again the second they return to their bed. Not a pretty sight to imagine at all, particularly as one female flea can lay up to 50 eggs!

This means to effectively treat your dog for fleas you also need to address their environment as well.

You can do this with the use of flea preventative products alongside an effective flea and tick shampoo.

Thoroughly wash all bedding and furniture if you can, deeply cleaning your home to ensure you successfully eradicate any sign of fleas, and their eggs.

Top 10 Best Flea & Tick Shampoos for Dogs

When choosing the best flea shampoo for your pet, it is vital that you take many factors into consideration.

In the individual reviews below we have done our best to consider some of these including how they performed, both in the short and long-term when we trialed them, as well as looking at their value for money and other aspects such as smell and how well they lathered.

As well as these factors, as already mentioned in this guide, you should pay particular attention to the ingredients used within some of the products.

We have tried to review a mix of products that are both organic, containing all-natural ingredients while many remain medicated shampoos as we did find these to be the most effective in combating fleas.

If you do decide to go for one of these medicated shampoos we do advise you consult your veterinarian firstly, just to double check any chemicals being used and the effect they may have on your dog’s skin and coat. All animals react differently to certain types of products, so this remains a crucial consideration.

The fact you have made it this far obviously means you are serious about the job at hand.

All of the shampoos reviewed in this list will allow you to do just that, however all with differing effectiveness.

Some of the flea shampoos reviewed also offer additional benefits such as moisturizing your dog’s skin and coat as well as fighting odor to leave your dog’s coat smelling fresher than ever.

Here are the top 10 best flea and tick shampoos we reviewed for dogs:

  2. Sentry Flea and Tick Shampoo


Sentry Flea Shampoo for Dogs

Sentry’s Flea and Tick shampoo comes packaging you wouldn’t immediately associate with a dog grooming product. Instead, it looks more like something you would see on your kitchen table but after reviewing the product ourselves we can confirm the contents are shampoo, and they are incredibly effective at helping to deter fleas from taking up residence on your lovely pet.

Priced very reasonably, Sentry’s flea and tick shampoo is hugely cost-effective, and one of the reasons it is so effective is the natural oatmeal ingredient that helps fight flea re-infestation.

We trialed the shampoo on two separate breeds of the dog, both large and small and saw the same positive outcome for both, particularly pleasing for such a budget-friendly product.

 3. Pet Pleasant’s Anti Itch Flea & Tick Pet Shampoo

Pet Pleasant’s Anti Itch Flea & Tick Pet Shampoo

Pet Pleasant’s anti-flea and tick shampoo is perfect for dogs with sensitive skin, containing no harsh chemicals that may irritate or inflame already problem areas.

The natural product means your dog’s skin does most of the work; the shampoo helps eliminate any little nasties without leaving any adverse effects.

Bio Spot is another excellent anti-flea shampoo which we found to be one of the longer lasting products among those we trialed.

The majority of flea shampoos will advise you to use the product once a week to fight any re-infestation, and although that is still a sensible way to ensure you are winning the battle over fleas we noticed that only using this product once a month still had the desired effect.

Not only that but we found the scent to leave the dogs we tried the shampoo with to extremely pleasing on the nose, while not being too overpowering to unsettle the dogs themselves.

   7.  Sentry Pro Flea and Tick Dog Shampoo

Sentry Pro Flea and Tick Dog Shampoo

The second shampoo product on this roundup from Sentry, the Pro flea, and tick dog shampoo is slightly more expensive, but the price should by no means put you off as we found this shampoo to be even more effective.

The ginger product scent makes a nice change from the usual ‘lavender’ smelling dog shampoos, and we found the product to be effective for killing fleas and ticks almost immediately.

This flea shampoo was also super long lasting, keeping them away for over two weeks and the product also advertises that it kills eggs for 30 days, giving you a helping hand in fighting off any re-infestation.

     8. Vet-Kem Ovitrol Plus Flea and Tick Shampoo

Vet-Kem Ovitrol Plus Flea and Tick Shampoo

Another shampoo we trialed that had a fantastic scent was the Vet-Kem Ovitrol plus.

Similar to the smell of a baby shampoo it left our dogs smelling like they were thoroughly clean and free of any unwanted fleas or ticks, a real bonus for dog owners.

Like the Sentry plus this shampoo kills off eggs and prevents them for hatching for 28 days meaning if you settle your dog into a regular grooming routine during this time you should give yourself the upper hand when fighting off fleas.

One last note is that the shampoo has a real texture to it, one of the reasons it leaves your dog feeling so fresh, and this also means a little product goes a long way so.

We have the bottle we trialed to be very long lasting which makes this shampoo budget-friendly as well.

    9. Fresh ‘n Clean Flea and Tick Small Pet Conditioning Shampoo
