Best Dog Flea Control Shampoos of 2025

"After working as a bather, I discovered this product. It kills ALL fleas after one use when applied correctly. I’ve used it on several dogs at the salon and my own pet. Letting it sit for 10 minutes is crucial; you can literally see the fleas fall off during the wash. It smells great and is not harsh. A little goes a long way, and it always works! I highly recommend it!"

"When my dogs picked up lice at the dog park, we were worried. After a vet visit, I tried this shampoo, applying it carefully around her neck first to prevent lice from escaping to her face. After just one wash, she stopped scratching completely! Her coat is so soft now, and she smells amazing, like baby powder. The absence of scratching is proof of effectiveness. I’ll use this regularly to keep both lice and fleas away!"

"Using the Adams Plus Flea & Tick Shampoo has been a game-changer for my two dogs. It provides thorough protection against fleas, ticks, and lice. The gentle formula is perfect for their sensitive skin, and I noticed a significant reduction in pests after just one use. It’s easy to apply and rinses off quickly, leaving their coats soft and shiny. Adams is a trusted brand, and I wholeheartedly recommend this shampoo for anyone with multiple dogs!"

"My pug, Oscar, is my prized companion. After rescuing him from the streets of Mumbai, I do everything to ensure his happiness. This is the only shampoo I've used that effectively keeps ticks and fleas at bay. For nearly three years, I've avoided medications like Bravecto, which feels like a huge win! We visit the park daily, and I no longer worry about pests. The smell is wonderful and eliminates any dog odors. It's thick, easy to apply, and one bottle lasts a long time. His coat looks snowy white and healthy, and I appreciate that it doesn't expose Oscar to harmful chemicals."

"After dealing with a terrible flea problem, I tried this shampoo on my two cavachons. I was horrified by the situation, especially with my daughter-in-law and granddaughter visiting. I bought numerous treatments, but this one turned out to be one of the most effective. After washing both dogs and letting it sit for 5-10 minutes, I noticed results immediately. I also supplemented with Frontline Plus for long-term control, and thankfully, both the dogs and my home are now flea-free. I will definitely continue to use this shampoo!"

"I just recently encountered my first flea issue with my dog, and it was a nightmare! I ordered this shampoo and used it right away. The fleas were dying almost instantly! Since the bath, he hasn't scratched at all, which is a relief. While the scent isn't the best, it's not terrible either. Overall, I would highly recommend this shampoo!"

"This shampoo worked instantly on my dog and left him smelling great. I highly recommend it!"

"I was terrified my dogs had fleas everywhere! After using this shampoo, it killed the fleas right on contact. However, I also needed chewable flea prevention for ongoing protection."

"I've used this on my labs before, and I bought it again because it smells so good and makes their coat soft and shiny."

“After using this shampoo, I only found 2 live fleas on my Yorkie, Zoe. Normally, I’d pull off 10-15 fleas after a bath. I brushed with shampoo on the brush, and Zoe smelled amazing. The blow dry was quick since I wasn't chasing fleas, and she’s sleeping well tonight. We started with Frontline Plus three days ago, so this shampoo will be our go-to for keeping Zoe flea-free. Highly recommend this shampoo!”

“I think this product is fantastic! It effectively killed all the fleas on my dog, and he hasn’t had any issues after using it. I would recommend it to anyone with dogs. It’s just as good as the pricier options.”

“I wasn't thrilled with the fragrance of the shampoo, but it still seems to help with fleas and ticks. The texture is thicker than other brands I've used, and my dog had no negative reactions at all. I’m relieved I haven’t found any fleas on her, especially since we live near small farms that can cause flea problems.”

"I left my dog with someone while I went on a trip, and when I returned, he had caught fleas. I quickly searched for the best products and found this. I saw the effects immediately, and the fleas were completely gone after about two uses. It has a nice smell after rinsing him off, but doesn't smell too good while washing."

"I’ve used this shampoo before, and it kills the fleas on the cats. They stayed flea-free for a while, so it works well. I love this shampoo! It leaves my dog's fur soft and smelling great for days."

"After I fully lathered and scrubbed my cat and let her marinate for about five minutes, I noticed it killed some fleas right away. It was satisfying to see them floating in the tub. However, it definitely did not get all of them. I plucked all I could see, but I feel there are still some hiding."

"This product worked wonderfully on my four dogs. I loved the pleasant scent, and I appreciated that it took only 5 minutes to work!"

"I found that this product works well. The smell is nice, and it helps significantly with fleas and itching on my dog."

"While it seems to suds up nicely, I haven't observed any dead fleas yet, but it does have a nice fragrance."

"I absolutely love this flea shampoo! It has a peppermint smell, is easy to rinse out, and has no side effects. My dog's coat feels soft, and it really does keep fleas away. I will continue to purchase this product."

"Using the product as directed, I left it on for 5 minutes and noticed a dead flea in the tub after just 2 minutes. The scent is wonderful, reminiscent of essential oils, and most importantly, it kills fleas effectively. I plan to give my pets another bath in a few days, and so far, I'm very impressed."

"This shampoo has been the best alternative outside of the groomer. It works immediately, especially compared to what I bought at Family Dollar. It has a minty scent, and I usually follow up with a fragrant shampoo after using this. My only wish is that the bottle was bigger."

"I found this shampoo to be really effective. After taking my dog to the dog park, I bathed him with this and all the fleas were gone. It’s a gentle shampoo that works well for a quick clean after outdoor play."

"I was impressed with this product. I needed something for fleas and ticks, and it left my dog’s coat soft and shiny. Not a tick in sight, and it even helps with her candida issue, though it’s not quite as strong as my previous shampoo."

"This shampoo did wonders for my dog. We soaked him first, lathered it on for the required time, and I could see the fleas were dead in the tub. After a few weekly baths, we noticed no more fleas at all."

“I absolutely love this dog shampoo! It works really well and has a great smell.”

“After my dog’s flea infestation, I used this shampoo, and I could see dozens of fleas drop dead in the bathtub after the first wash. It’s really effective! You need to use it daily at first, then weekly to keep the fleas away. Very satisfied with this product and it’s affordable too!”

“This shampoo really does the job! You can see fleas rinsing off during bath time, which is a huge relief.”

"I bought this shampoo last summer due to unwanted little creatures infesting my dog. During the bath, I could see them fall dead, indicating it really kills fleas. The oil has a pleasant scent, and even the next day, my dog still smells good. I highly recommend it—great value for the money."

"Initially, I was skeptical about its effectiveness. However, after drying my cats, I noticed three dead fleas on the towels. Even though my cats might not enjoy another bath, I plan to do it again next week to ensure all fleas are gone. I love the smell and ease of use, and I'm willing to buy it again if needed!"

"In my 38 years with cats, I've only dealt with fleas twice. This time, I wanted to avoid chemicals, so I tried this product, believing the positive reviews would hold true. Unfortunately, after following the instructions, my long-haired cats began losing fur, and one has become lethargic. I’m incredibly frustrated and will be returning the unused items!"
