Last Updated: // Author:

If you’re searching for the best Flea Shampoo for Dogs, you’ve probably done everything to keep ticks and fleas off your dog. You’ve avoided walking in tall grass, pulled your dog away from that stained couch that’s been rotting on the sidewalk for weeks, and you’ve even stopped taking Fido to the park to socialize with other dogs in fear that one of them has fleas.

But alas, despite your efforts, those pesky parasites have somehow infiltrated your dog’s coat, your home, and what feels like your entire life.

You’ve already tried the homemade remedies you’ve found online, but the dish soap and vinegar mix seem ineffective in this crisis situation.

Luckily, there are many tried-and-true dog shampoos out there that will quickly and effectively rid your pooch of fleas and ticks so that he can get back to playing and you can get back to, well… fumigating your home.

Ticks, Fleas, and what to look out for

So how do you even know if your dog has ticks or fleas? Hopefully, you are already paying close attention to your dog’s coat and skin during regular grooming. If you’re not, it’s a good idea to carefully check your dog for fleas at least once a week, especially if he spends a lot of time outdoors or around other dogs.

If your dog is frequently in tall grass, in the woods, or if you live in an area where ticks are prevalent, we recommend checking your dog every single day for ticks. This can be done by dragging your fingers through their fur with enough pressure to feel for any unusual bumps on the skin (Source). Ticks can range in size and color depending on how long they have been embedded. Smaller ticks that are black or dark brown have been on your dog for less time than a large tick that is grey or white.

Ticks can be very dangerous to dogs (and to humans), with infections possible within 24 hours (Source). Any ticks found must be removed as soon as possible, by using a special shampoo or other treatment, by gently using tweezers, or by taking your dog to a veterinarian. Ensure that the entire tick is removed from the dog’s skin, and then gently wash the affected area.

There are several ways that you can tell if your dog has fleas. The most obvious sign is unusual scratching, licking, or biting of areas like the head, neck tail, armpits, and groin (Source). You should also look out for unusual red patches of skin or hair loss (signifying an allergic reaction). Another telling sign is the presence of black or reddish-brown “dirt” on your dog or in your home. This “dirt” is actually your dog’s digested blood that the fleas have expelled. It is important to take steps to rid your dog of fleas as soon as possible since they can be extremely irritating and cause infection. Fleas can spread rapidly, so you should also check your home and yourself for fleas if you find evidence of them on your dog.


Repellents vs. Treatments

When choosing the right products for your dog, make sure you understand the difference between repellents and treatments. While repellents may help keep fleas and ticks away from your dog, they may not be useful once your dog has already been infected.

There are many tools and tricks that can be used to combat fleas and ticks, and it can get pretty confusing to sort them out and decide which is best for your dog. For example, you may be familiar with the oral medications that you can give to your dog that will prevent or kill existing fleas or ticks. These medications can be expensive, and they are not always 100 percent effective. In addition, you must decide if you want to take the risk of administering a medication orally rather than topically (just to the affected area). Oral medications to prevent and treat ticks and fleas might be the best option for dogs who are at high-risk of coming in contact with the parasites.

Other solutions include special flea and tick collars, and sprays. The flea and tick collars and sprays work to repel bugs from coming in contact with your dog. Some sprays can even be used after exposure to kill fleas or ticks. While these prevention techniques are usually more natural than others, they are not very effective and aren’t recommended for dogs who are at high-risk for getting fleas or ticks.

The best place to start in your fight against fleas and ticks is to use a flea and tick shampoo to bathe your dog. These special shampoos can kill fleas, their eggs, and ticks. In addition, they provide the added benefits of soothing a dog’s skin and can prevent recurrence of fleas for a short time until you can eliminate their source.


What to look for in a Flea and Tick Shampoo

There are three general types of flea and tick shampoos available: chemical-based, natural, and organic.

If you are just looking for the best, most effective, and quickest way to rid your dog of fleas, don’t even bother with natural or organic shampoos. While chemical-based shampoos do pose a greater risk of causing adverse side-effects, most dogs will not have any issue in tolerating them, and they will be very effective at killing unwelcome parasites. Important active ingredients to look for if you want a fast-acting, chemical-based shampoo is pyrethrins, pyrethroids, and dioctyl sodium sulfosuccinate (docusate sodium).

Natural and organic flea and tick shampoos do not contain any chemicals but fight fleas and ticks using natural plant extracts and oils. For example, clove oil and cottonseed oil have shown some effectiveness in killing fleas and ticks. Organic shampoos contain all-natural ingredients (oils, butter, and extracts) that are certified to be organic.

Use personal preference to pick the best shampoo for your dog, and rest easy knowing that even if you are looking for a more natural solution you can still get rid of those pesky fleas and ticks.

What is the Best Flea Shampoo for Small Dogs?

If you have a smaller Dog, you don’t necessarily need to get a specific type of Flea Shampoo. Just make sure you read the directions carefully, especially for concentrated shampoos as the amount you need to use may be much smaller than that of a larger Dog.
