What’s more, the added Precor provides 28 days of control of pre-adult fleas, killing them before they become biting adults, helping to break the flea life cycle and get rid of infestations for good!

Our Runner Up Pick: Hartz UltraGuard Flea & Tick Dog Shampoo
People who regularly bathe their dogs might find that Hartz UltraGuard Flea & Tick Dog Shampoo meets their needs. Although it only kills fleas and ticks on contact (with no preventative powers), it’s safe to use up to once a week, so you can add it to your four-legged friend’s regular bathing routine.
The citrusy smell helps to deodorize your dog without being overpowering. Although we’re focusing on the citrus version, you can also buy a “fresh” scented option and an oatmeal option that’s good for itchy skin. It’s suitable for use on all dogs over 6 months old.
Retailing just $3 for an 18-ounce bottle, it works out even more affordable than our top pick, although you may decide the added 28 day protection it gives you is worth shelling out a little more for.

Best Budget Pick: Sentry Flea & Tick Shampoo with Oatmeal

The oatmeal formula is designed to soothe dry and itchy skin, which is good news if your four-legged friend is itchy from flea bites.
Most users say they love the Hawaiian ginger scent of this shampoo, which makes a change from some of the more medicinal smelling flea treatments. As well as killing fleas, it effectively cleanses and deodorizes your dog and is pH balanced for a healthy coat and skin. At around $7 for an 18-ounce bottle, it’s not too bad on the wallet, either.

Best Natural Flea Shampoo for Dogs: Wondercide Natural Flea & Tick Shampoo Bar
If you’d prefer to tackle fleas in the natural way, or would like some top-up preventative action in between topical flea treatments (such as spot-on treatments), we’d highly recommend theWondercide Natural Flea & Tick Shampoo Bar.
It’s slightly different from an average flea shampoo (even a natural one) in as much as it’s a solid shampoo bar, rather than a liquid. Not only does this mean it’s less messy and easier to store, it also has the benefit of requiring no plastic packaging, making it an eco-friendly choice.
It contains just coconut oil, palm oil (sustainably sourced), shea butter, castor oil, citronella oil, geranium oil, aloe vera, vitamin E, and honey. While there are mixed reviews about how effective it is, the idea is that the natural essential oils can both kill and prevent fleas and ticks. Many users swear by it, but some question how effective it is, so you may just need to try it and see if it works for your pet.
Although the manufacturer states each 4-ounce will last around four washes for a medium-sized dog, some buyers state it lasts them a dozen washes or more. So, although it costs $15 for a single bar, it does go a long way!
Wondercide Natural Flea & Tick Shampoo Bar Key Features:
- All-natural ingredients
- Solid formulation means no plastic packaging
- Leaves coat soft and moisturized
Best Flea Shampoo for Dogs with Sensitive Skin: Veterinary Formula Clinical Care Flea & Tick Shampoo
You might think you’ll need to stick to natural flea shampoos for a dog with sensitive skin, but that’s not necessarily the case. Veterinary Formula Clinical Care Flea & Tick Shampoo is a strong formula with triple strength Pyrethrin as the active ingredient. But as it’s PH-balanced, and free of damaging detergents, irritating soap, and parabens, you can rest assured that it will be gentle on your dog’s sensitive skin.
It kills fleas and ticks on contact, but it won’t provide ongoing protection, so you will need to bathe your dog regularly, or use it in conjunction with another form of flea control. This flea shampoo for dogs have a light, clean fragrance that gets rid of bad doggy smells, but doesn’t linger for too long.
With a price tag of around $6 for a 16-ounce bottle, it’s an absolute steal considering how high-quality the formula is.
Veterinary Formula Clinical Care Flea & Tick Shampoo Key Features:
- Soap and paraben free
- Clean scent
- Triple strength formula
Who Should Buy Flea Shampoo for Dogs?
The unfortunate truth is that dogs can easily pick up fleas and ticks, whether playing with other dogs or exploring the undergrowth. As such, you need to find a method for either killing fleas, preventing fleas, or a bit of both. You can find plenty of flea treatments on the market, so who should buy flea shampoo for dogs?
Well, first off, flea shampoo is only a good idea for people who bathe their dogs regularly and/or whose dogs tolerate bathing well. If bathtime is a nightmarish struggle, you might be better off with a different kind of flea treatment. Some flea shampoos are also handy to prevent or remove fleas and ticks in between other flea treatments (tablets or topical “spot-on” treatments, for instance). However, you should always check your chosen flea shampoo can use used in conjunction with other treatments, if this is what you have in mind.
Important Features to Consider
A flea shampoo should do several things well. Here’s what to consider when selecting a flea shampoo for your dog:
- Efficacy. Arguably the most important factor to consider is, does it actually work? Unfortunately not all so-called flea shampoos do what they say on the bottle. Check out some customer reviews to make sure the shampoo you’ve chosen is effective.
- What it eradicates. The vast majority of flea shampoos eradicate both fleas and ticks, but a handful don’t work on ticks, so always double check if you’re after some tick-killing action. Also check whether your chosen shampoo works only on adult fleas, or on larvae and/or eggs, as well. Those that also get rid of immature fleas can help break the life cycle and completely quash your pet’s infestation.
- Preventative powers. Unfortunately, a lot of flea shampoos only kill fleas and ticks on contact, but offer no flea prevention. That said, you can find flea shampoos that either help prevent reinfestation or keep on killing fleas for another 1 to 4 weeks.
- Package size. If you’re looking for good value, always check the size of the bottle, as well as the price. Bottle A might cost a couple of dollars more than bottle B, but if bottle A is twice the size of bottle B, then A gives you more bang for your buck.
- Scent. Floral, fruity, or straight up medicinal, different flea shampoos have different scents. While it’s hard to tell whether you’ll like the smell without giving it a whiff in person, customer reviews can tell you what most buyers think.
Frequently Asked Questions
How often should I wash my dog with flea shampoo?
Sure, you want to get rid of fleas, but overdoing it with the flea shampoo isn’t a good idea. If you choose a variety that contains chemical pesticides, using them too often can be bad for your dog, plus flea shampoos can be drying for your four-legged friend’s skin. While you can wash your dog with flea shampoo as often as once a week, if she has an active infestation, we wouldn’t recommend regularly using flea shampoo this often. If your chosen flea shampoos can prevent infestation, bathe your dog with it every month or two. If it only kills, but doesn’t prevent, fleas and ticks, you only need to use it if and when you notice your dog has fleas.
Will flea shampoo get rid of fleas on my dog?
Flea shampoos that kill eggs and larvae, as well as adult fleas, should completely get rid of your pet’s flea infestation. Although, you should also treat the house, otherwise fleas living in your carpet and upholstery can hop back onto your pooch. Flea shampoos that only kill adult fleas, however, will leave eggs and larvae to mature into adult fleas on your pet, so you’ll either need to shampoo your dog once a week for a month or so, or use an additional treatment that kills immature fleas, too.
Does flea shampoo expire?
Yes, flea shampoo does expire, although the expiration date is often a long way off. Still, always check the expiration date before soaping up your dog. Expired flea shampoo may not kills fleas effectively.
Will regular dog shampoo kill fleas?
No, regular dog shampoo will not kill fleas. You need to use flea shampoo to tackle an infestation.
