Buyers Guide

Dog Flea Treatments Buyer's Guide

Almost all dogs will have to deal with a flea infestation at some point in their lifetime.

Fleas are wingless tiny insects that wreak havoc in your pooch's life. What are fleas exactly?

They are blood-sucking pests that often leave behind painful bite marks. These bite marks eventually will become a source of itch for your dog. Hence, the most common symptom of a flea infestation – excessive scratching.

Even we as humans are not immune to fleas. Fleas can spread from your canine friend to you. What makes them so frightening is it's ability to multiply in a few short days.

There are several forms of flea treatments available in the market that are effective and reliable. However, choosing the right one might not be as easy as it seems. You must understand the flea life cycle, the active ingredients and their side effects.

Here we have covered all the necessary grounds to ensure you are well informed before you make this purchase for your pooch.

Why Are Fleas Infestation Serious?

It is not just itching and allergies that fleas cause in your dog. They can also lead to tapeworm infestation, anemia and overall lethargy in them.

  • Tapeworm Infestation: Dogs can get easily infected with tapeworm when they have fleas. Why? Because fleas are known to be tapeworms carriers. Tapeworm infestation will affect the gut of the canine and lead to serious digestive problems. If left untreated, it can turn fatal based on the dog's overall health.
  • Bacterial Infection: Fleas are a carrier for multiple sources of harmful bacteria which can cause vomiting, nausea, seizures in your dogs. To prevent these fleas must be eradicated.
  • Anemia: It is very common for dogs with severe flea infestation to have anemia because these pests are consuming blood from them. A drastic drop of red blood cells (or known as Anemia) can cause lethargy in your dog. Especially for young puppies, Anemia is a potentially life-threatening condition. So always check your dog for any fleas related symptoms.

Therefore, it is important not to underestimate the severity of a flea infestation. When in doubt, always seek professional medical advise from a local licensed veterinarian.

Types Of Common Flea Treatments

There are quite a few flea treatments that are available in the market. At times, you might have to use a combination of them to achieve effective flea removal results.

The common types of treatment are:

  • Spot Treatment: In this method, liquid or ointment is applied to any two to three spots on the pet's back. This is a preventive method and must be done on a monthly basis.
  • Flea Collars: These are collars that can be worn by the pet to prevent fleas from attacking them. They are effective for several months. They cannot be a replacement for a regular collar though.
  • Dips: These are a little more complex and need greater care while handling. The dips kill existing fleas directly and prevent new ones from coming.
  • Flea Shampoo: Washing the pet once a month with the shampoo will ensure that the existing fleas die but it does not prevent new ones from coming. Hence, this treatment must be used in conjunction with another treatment.
  • Flea Spray: Just like the shampoo, the spray can kill existing flea but cannot prevent new ones from coming. It too must be used in combination with other treatments to eradicate fleas completely.
  • Oral Treatment: These medications prevent the adult from laying more eggs but do not kill the existing larvae and eggs and flea. For that, you must use a treatment that kills them.

What You Should Look Out For?

  • Speed of Treatment: Fleas can torment your dog no end and you need a treatment that acts fast and gives relief quickly. A good treatment will give relief within minutes.
  • Works On Entire Lifecycle: It is no use killing only the adult fleas because the larvae will grow and the fleas will come back. A good treatment will be comprehensive and kill not only the adults but also the eggs and the larvae and prevent re-infestation. As an added precaution, it is highly advisable to make use of different flea treatments to kill existing fleas and to prevent new ones from occurring.
  • Ingredients: The ingredients used in flea treatment must cause minimal to no side effects. There is a concern about the presence of Permethrin and Pyrethroids which should be avoided in all cases. If consumed in large quantities, these ingredients could potentially be fatal to dogs.
  • Spray VS Oral Tablets: It must be easy to use, non-sticky and with mild or no odor at all. It must be easy to apply. Not all dogs like applications. Hence, you must choose either a tablet or a spray based on your dog's preference.
  • Size of Dog: The dosage of treatment also depends on the dog size and breed. Usually a bigger dog requires a larger dosage. Be sure to check the packaging before buying, as there are different flea treatments for different weight classes of dogs.

Fleas Can Be Anywhere

It is never enough to treat just the visible fleas. You must eradicate the problem from its root and that is possible only when you target the eggs, larvae and pupa of fleas. You need a treatment that will deal with all the three stages in the flea's life.

It is also, therefore, necessary to treat the dog house and all areas that the dog frequents. This includes your beddings and bedsheets too.

Generally, most will recommend a DIY flea treatment for healthy adult dogs. If you have puppies or expectant dogs, you should bring your dog and consult a licensed veterinarian instead.

How To Make Your Home Flea-Free?

Hygiene starts at home. You must vacuum your house on a regular basis. Do not miss any nooks, corners, behind and below sofas. Particular attention must be paid to seats and bedding which your pooch frequents.

Regularly groom your dog using a flea catching comb. Regular combing will keep the coat shiny and free from fleas, along with their larvae and eggs.

Mow your lawn regularly and keep the length of the grass low and manageable because fleas can survive on grass too.

Clear all clutter that attracts fleas and mosquitos and ticks.

Additional Flea Treatment Safety Tips

These tips ensure that you use the treatment right and protect not only your dog but other pets too.

  • Dog flea treatments are not meant for cats. Do not use the treatment on cats.
  • Knowing your dog's actual weight is crucial in purchasing the right treatment. Most flea treatment doses are formulated based on the dog's weight. A small dose might not be enough to kill all the fleas, while a big dose can be potentially fatal.
  • Follow the age requirements before using any treatment for puppies and small dogs.
  • Do not overuse the treatment.
  • Keeping the surroundings clean and clutter free can also deter flea infestation.

Keep Those Pesky Fleas Away!

With the market flooded with flea treatment products, choosing the right can be a daunting task. From our research and analysis, the Bayer K9 Advantix II is our top choice.


The flea treatment is safe to use and is trusted by dog owners for its effectiveness. Also, it starts killing fleas within 10 minutes. The Bayer K9 Advantix II ensures that your dog is free from all forms of fleas, ticks and mosquitos.
