Important Features to Check when Buying the Best Flea Shampoo for dogs

There are several things a flea shampoo must handle properly. Below are some things to put in mind when choosing a very reliable dog flea shampoo.

What does it eradicate

Most flea shampoos get rid of both ticks and fleas; however some don’t work when it comes to ticks, so you must cross-check if you want this shampoo to handle ticks as well. It is also great to check if it works effectively on just adult fleas or only on eggs and/or larvae as well. Shampoos that kill immature fleas will perform well to break its life cycle as well as completely handle your pet’s infestation.


Fruity, floral or straight up medicinal, flea shampoos usually have different scents. Though it’s difficult to tell if a product will smell nice without whiffing it in person, you can have an idea from customer reviews.

Preventative Powers

Sadly, so many flea shampoos pout there only kill ticks and fleas when they come in contact with them, but they don’t offer flea prevention. With this, you can easily search for shampoos that both kills fleas continuously for the next one to four weeks, or one that prevents reinfestation.


This is the most important factor to look into. You need to know if your choice of shampoo works. Sadly, not all flea shampoos perform what they are meant for. Take some time to check customer reviews on the intended products before making your decision.

Size of the package

If you need a flea shampoo with good value, then try to consider the price as well as the bottle size. If the first bottle is a few dollars costlier than the second bottle, but the first bottle is 2x the second bottle size, then bottle A offers you more money compared to bottle B.


This is another important factor you have to consider before purchasing a flea shampoo. You must avoid harsh chemicals that could harm or hurt your dog. Read the label properly and search for natural ingredients having soothing properties. Most times, pesticides are usually included in these shampoos and you never can tell if your dog is allergic to this; so you should go for flea shampoos having aloe and oatmeal so that even when it causes your dog some reaction, these ingredients will step in to soothe the skin.

Must-Know Tips when Using Flea Products For Dogs

The following are tips you should know about fleas and flea products for dogs:

  • Anytime you notice fleas on your dogs, treat them immediately, otherwise, the treatment should begin during the start of a flea season.
  • Check with your vet before using any flea shampoo on your dog. This is very important especially if your dog has a puppy, is sick, old, pregnant or nursing, taking other drugs, allergic to flea products, or has a history of seizures.
  • Ensure you wear gloves, and wash your hands with soap and water after applying the shampoo.
  • If you have more than one dog, keep them apart to ensure the product dries so they don’t end up swallowing the chemicals as they groom each other

Frequently Asked Questions

What does a Flea Shampoo mean? Why do I need it?
Flea shampoos are medicated products designed to get rid of fleas and their eggs, as well as prevent them from going back to the coat or skin of your dog. The natural and very effective ones will also soothe irritated areas and take care of your dog’s coat and skin.

Basic flea shampoo can also be made at home simply by mixing vinegar, warm water, and liquid soap. While this mixture has been very effective for some, there’s a bigger task in mixing these ingredients in the right amounts.

This homemade shampoo could also make things worse by increasing the itching and drying out the skin the more.

How Frequent should my dog be washed using a flea shampoo?
True, you must do away with fleas, but doing this too frequently isn’t a nice move. If you pick a shampoo that includes chemical pesticides, making use of them frequently could turn into a negative experience for your pooch.

While washing your dog using a flea shampoo can be done once every week, if your dog has an active infestation, then we will advise that this flea shampoo shouldn’t be used regularly. If this flea shampoo can get rid of the infestation, then you should bathe your pet dog using the formulation every one or two months.

If this shampoo kills ticks and fleas but cannot prevent them, then you should only use it anytime she has fleas.

Will flea shampoos kill fleas on the body of my dog?
A flea shampoo that works perfectly well to get rid of eggs, larvae and adult fleas will work perfectly fine to kill fleas infesting your dog. Although, the house should also be treated, otherwise fleas hiding in your upholstery and carpet can find their way back to your pooch.

Shampoos that kill just adult fleas will leave larvae and eggs to mature on your dog, so you must shampoo her once every week and should last for a month. You can also make use of other treatment options that handles immature fleas as well.

Who should purchase flea shampoos for their dogs?
The bitter truth is that dogs easily pick up ticks and fleas while exploring the undergrowth or playing with other dogs.

Due to this reason, you must find another method, either for preventing fleas or killing fleas or a bit of the two. Lots of flea treatments can be found on the market, so what category of people should purchase flea shampoos for their dogs?

First, flea shampoo is only great for those who bathe their dogs regularly and/or whose dogs can tolerate bathing properly. If her bathtime is usually a tough struggle, then you should better make use of different flea treatment.

Some flea shampoos can prevent or get rid of ticks and fleas in between other flea treatments. If this is what you want, ensure you check the product you’re going for if it can be used with other treatments.


When we talk of handling conditions such as irritated, dry, and itchy skin, shampoos can also be considered as a health product.

Just like other health products, you should speak with your vet before going ahead to buy and use the best flea shampoo for dogs . Your dog may have some negative reactions to the ingredients, and only your vet will be able to give the best recommendation.

You must also note that how different dogs react to the different bands vary, so it shouldn’t be surprised to see your dog having allergies to the same shampoo your Labrador adapted well to.

You should also remember that some shampoos can be designed for different ages. Some can be used for both puppies and dogs, while others are strictly for puppies and some others strictly for adult dogs.

Finally, pet owners must know that flea infestation might require something more than a shampoo. If this is persistent and your dog isn’t comfortable with it after all attempts, then visit your vet immediately.
