Hazards Associated With Some Flea Products

Products intended for the treatment of shot dog fleas are regulated and approved by the FDA or the Environmental Protection Agency (EPA). However, some commercial dog shampoos and flea control products still contain toxic chemicals. Although these chemicals can effectively kill fleas, they can also penetrate the skin into the dog’s body and over time cause health problems.

In 2009, EPA reported an increase in health problems in dogs following the use of flea treatments, including shampoos. The Human Society of the United States and the Center for Public Integrity (CPI) have also published reports showing that health problems associated with conventional pesticides have increased by almost 300% over the past ten years.

Avoid These Ingredients In Regular Dog And Flea Shampoos     

Some ingredients in pet shampoos are directly related to health risks in dogs. This is what you should avoid with your next purchase:

  • Anise oil
  • Boric acid
  • benzene hexachloride
  • Naphthalene
  • Pine tar
  • sodium arsenite
  • Benzethonium chloride
  • chloranil
  • DDD
  • Depentene
  • dimethyl phthalate
  • menthol
  • Sodium bicarbonate
  • Xylene

It is clear that even when the FDA and EPA try to check that only animal-friendly and safe products are on sale, some dangerous items still end up on the shelves. Be careful what you buy; use a dog shampoo that contains harmless ingredients that are safe for your dog and you, while effectively killing fleas.

The Safest Best Flea Shampoo for Dogs

UltraGuard Rid Flea & Tick Shampoo  

The first on our list of the best shampoos for dogs is the famous brand Hartz. The active ingredient is phenothrin, a synthetic pyrethroid. It is useful in killing adult fleas, ticks, mites and many other insects and parasites. The inactive ingredient in the shampoo is oatmeal, which soothes the skin and accelerates healing. It is safe for dogs 6 months and older.

This shampoo is generally faster and requires less bathing per week (depending on the infection). What’s more, it doesn’t hurt your dog’s eyes, while most synthetic shampoos have a penetrating effect when the foam comes close to your eyes. The biggest problem is that many flea products have an intoxicating smell, and this is one of the worst we’ve tried – it smells terrible.


    • At an affordable price
    • It works fast, killing fleas, ticks and mites.
    • Formula with oat flakes to soothe the skin
    • Safe for dogs older than 6 months.

Ovitrol Plus dog flea shampoo

by Vet-Kem

golden retriever

Manufactured by a famous health brand, this is the most potent dog flea shampoo on the list because some pests just need to be used a little more effectively (and only after consultation with your vet). Ovitrol Plus from Vet-Kem contains pyrethrin and piperonyl butoxide as active ingredients in a concentration of less than 2%. These components are typically found in anti-lice and anti-flea shampoos. They are most effective in killing fleas.

Its ingredients interrupt the life cycle of fleas in early adulthood and kill sleeping flea eggs, larvae and pupae. This prevents the recurrence of a new generation of fleas and provides a control for up to about one month. Among the unnatural and natural dog, the shampoo also had the best smell.


    • Strong, effective
    • Pleasant scent
    • 98% of the ingredients are natural
    • Kills adult fleas on contact and interrupts the flea life cycle in pre-mature stages.
    • Provides up to one-month flea control for


    • Expensive
    • Very strong, maybe not suitable for some dogs.

Flea and tick shampoo with Precor

by Adams

small dog posing

Many different flea dog shampoos kill adult fleas. Still, only a handful of them actively kills their eggs and pre-adult fleas. Adams Plus contains pyrethin and piperonyl butoxide, which have been shown in studies to work effectively together to kill adult fleas. It’s not a natural shampoo like some of the better dog flea shampoos mentioned below, but we’ve found it to be more effective in its work.

It is less mild than Hartz but slightly more effective through the use of pyrethin. When used with a good flea comb during and after each bath, it will eliminate hundreds of fleas in one session. Adams Plus Dog’s flea shampoo has not only left the fleas clear (and visible) but can also solve the ticking problem, as others report. Less scratching and itching in dogs can be due to a combination of other cleansing and moisturizing ingredients. But again, the smell could be better (although not as bad as that of Hartz).


    • Very effective.
    • Kills fleas, ticks, flea eggs, flea larvae and lice
    • Contains aloe, coconut extract, lanolin and oatmeal to cleanse and moisturize the skin.
    • Keeps fleas and ticks away longer


    • Slightly expensive
  • Bad smell

Natural flea shampoo for dogs

For those who are looking for a completely natural product, this was the winner for us. When it comes to a gentle and natural flea shampoo for dogs, Wahl’s Rosemary and Mint Natural is very effective against fleas and ticks, yet soft and safe for the dog and its owner. It does not contain PEG-80, a detergent that is common in dog flea shampoos and is known to have long-term harmful effects.

It foams and rinses off much better, and unlike the other best dog shampoos listed here, our dog’s skin is much less prone to drying out. After rinsing, the fleas fall down the drain, and you can apply the shampoo more safely to your dog’s head, face and behind his ears, which are designed for fleas. It is gentle enough not to irritate your dog’s eyes, nose and skin. It also smells much better than these two brands.


    • At an affordable price
    • All-natural and herbal ingredients
    • Only FDA-approved fragrances and dyes were used
    • flea and tick defence for up to 1 week  


    • Not suitable for all dogs
    • Not as durable as some other brands
    • Will not be active in case of severe flea infestation

Flea and tick shampoo with oatmeal

from Sentry

cute dog with nice hair

Sentry shampoo for fleas targets both fleas and ticks and kills fleas immediately after bathing and ticks after about a day or two after bathing. However, its effectiveness reaches its peak 7-10 days after the first application. It should be used weekly until all parasites are eliminated. Like the mentioned brand, it is an intense treatment.

Most dog shampoos for fleas are very thin, compared to Sentry Shampoo has a very thick consistency and foams very well. It goes a bit far, making it a very economical solution, or at least part of the solution. Our dogs also loved the massage that accompanies every bath with Sentry Shampoo. After all, it also has a slightly pleasant smell.


    • At an affordable price
    • It kills fleas and ticks immediately within 48 hours.
    • Keeps fleas and ticks away for up to 10 days.
    • Contains oatmeal, which moisturises, cleanses and deodorises the skin.               


    • The last batch of this shampoo was thinner than the syrup we got from the original purchase.
    • Ineffective for all dogs and pests

The different types of flea shampoos

One thing is certain, anti-flea shampoos are not what is missing on the market. On the contrary, you will have so many proposals that you risk having a choice problem. The other aspect that may also influence your decision is the type of shampoo you should take. Should we look for a shampoo based on natural products or should we opt for chemicals. In any case, there are many who think that natural products are the best in terms of cost and also effects, but you should also know that these types of shampoos are less effective. So do not rule out the chemical ones as they are more apt to give you positive results in the shortest possible time. The power of these shampoos suffers from no doubt. However whatever your preferences, you should especially take into account your dog’s sensitivities. Because, after all it is on him that you will apply it.

Can fleas make your dog sick?

Think again if you believe that fleas are not as dangerous for your dogs. Your dog can, in fact, suffer a lot because of these parasites because they feed on your dog’s blood. Fleas suck your dog’s blood for food. Suddenly, your pet can easily get sick before becoming weak. Also, your dog may go crazy and won’t even want to be near you. With the presence of fleas on his skin, the dog may end up with an intense itch and irritated skin. Which will disturb his sleep at night. Another problem caused by the presence of fleas in dogs is the reduction of the dog’s immunity. Not to mention that they can also carry tapeworms. Yep, a dog with fleas on its skin may end up with tapeworms,

So do not underestimate the fleas on the dog’s skin because even you, you can be a victim of the presence of these parasites in your dog. Do not expect anything, if your dog cohabits with fleas it is necessary to treat them as quickly as possible with the best anti-flea shampoo.

Other ways to fight fleas

However, using flea shampoos is not the only solution to get rid of these parasites on your dog’s skin. And as the saying goes, prevention is better than cure and by getting the best flea collar , you can prevent your dog from the ordeal of living with these parasites which may destroy it completely. But, if fleas have already invaded your dog’s body, flea shampoos are recommended most of the time to relieve your pet because they are very effective.

Only, you should not forget that flea collars are only effective for a specific time. Which time depends on the type of necklace you have chosen.

Anti-flea sprays are also solutions against fleas. Just apply them around the house and you and your dog are protected. But here too, the chemicals in the spray can be very dangerous. And faced with these multitudes of drawbacks, it is recommended to use a combination of product, it is the best way to fight fleas.
