Flea spray for dogs will help you keep your pet parasite-free without much hassle – they work immediately and are easy to apply. Take a look at our selection of the best flea sprays for dogs and make your pick!

Keeping fleas under control can be such a hassle – once they make a home in your pet’s coat, they’ll quickly infest everything around them, and getting rid of them for good is definitely a challenge. A flea spray for dogs can help you take matters into your own hands. Unlike some products formulated to kill fleas, sprays are easy to use, effective, and can be used every step of the way – both treating the dog, and the areas infested with fleas.

This is something that not many people know, but no product for fleas will effectively work unless you use something to eliminate the fleas from your home and/or yard. If you skip this step, flea larvae and eggs will mature to the adult form and once again infest your pet. And they are sneaky, too: fleas can hide in carpet fibers, pet beds and bedding, inside furniture, even in cracks of hardwood floors. A flea spray for dogs covers all of your bases, as most can be used both on pets as well as outdoors, on carpets, rugs, upholstery, and bedding. One product to tackle it all!

There are various types of flea sprays for dogs, from those that boast a natural-only formula to those that rely on potent insecticides, with different formulas and properties. Read on to find out which is the best choice for your own pet – and make your choice.

Fleas are not picky when it comes to age – they’ll bite anyone and everyone, puppies included.

Luckily, there are flea sprays for dogs that are made from natural ingredients but are still quite effective at eliminating these parasites – such as this formula that relies on natural essential oils. The active ingredients are clove oil, cedarwood oil, lemongrass oil, and cinnamon oil, all known for their repelling and eliminating effect on fleas and their larvae, as well as ticks.

6. Best for Outdoor Use: Vet’s Best Flea and Tick Yard and Kennel Spray

To truly eradicate fleas, you need to focus on more than just treating your pet. You have to use a flea-killing product in the area where your pet spends time to make sure that there are no larvae or eggs left behind that will develop and hop on your pet again as soon as given a chance. This means spraying bedding, furniture, even carpets in places your pet sleeps in or frequents – but also outside in the yard, especially if they use a kennel. Vet’s Best Flea and Tick Yard and Kennel Spray is formulated precisely for outdoor use, with a ready-to-use hose attachment nozzle that makes the process fast and effortless. The active ingredients in this formula are peppermint oil and eugenol, which allows this product to kill mosquitoes, fleas, flea larvae, flea eggs, and ticks on contact. This product is not harmful to pets, plants, or trees, and can be used on turf and grass areas.


  • Convenient hose attachment nozzle
  • Kills parasites on contact
  • Natural ingredients


  • Using the hose nozzle takes some trial and error

7. Best for Carpets: SENTRY HOME Flea and Tick Home and Carpet Spray

When you’re eliminating fleas from your home and your pet, you need to really get in there and spray every little nook and cranny to leave no bloodsucker behind. This includes carpets – fleas often embed themselves in the carpet fibers, lay their eggs there, and hop on your unsuspecting passing pet when they get hungry. To prevent reinfestation after using a flea spray on your dog, use a spray to treat their surroundings – such as this one, which is formulated for use on carpets, rugs, bedding, and upholstered furniture. The active ingredients in the formula are pyriproxyfen and permethrin, which ensures fleas, ticks, flea eggs, and larvae are killed on contact. To boot, this spray will also prevent future reinfestation by preventing eggs and larvae from maturing – the effect lasts up to 210 days. And to make things even better – this spray has a deodorizing effect, as well.


  • Eradicates fleas from carpets, upholstery, and bedding
  • Deodorizing effect – great for pet bedding
  • Prevents future infestations for up to 210 days


  • The bottle isn’t practical to use – the sprayer could be stronger

What to Look for in Flea Spray for Dogs

There are hundreds of flea sprays for dogs on the market, but they are not made alike. Some work better, some are less effective, some are safe for puppies, and some kill only adult fleas instead of larvae and eggs. In a nutshell, different formulas have different potency and different uses, so you’ll have to consider various factors before you pick out a flea spray for your dog.


The most important factor to pay attention to is, by far, the formula of a flea spray for dogs. There are flea sprays made from natural ingredients such as essential oils, and those that use insecticides, most often pyrethrins, permethrin, or pyriproxyfen. Both are effective, but insecticides are more potent and faster-acting, albeit some pet parents avoid them because of the direct contact they make with the pet’s skin.

Scope of effect

Not all flea sprays target the same parasites – and the same life stages of parasites. The best and most effective flea sprays will eliminate these parasites in all of their forms: flea eggs, flea larvae, and adult fleas. This prevents the young forms from maturing and re-infesting your pet. Additionally, there are flea sprays that also work on other types of parasites, such as ticks, lice, and even mosquitoes (which are dangerous because they transmit heartworm).

Dosage & age

Make sure that the flea spray you pick is safe for your pet to use, both according to their weight and their age. There are some flea sprays for dogs that can’t be used on dogs under 6 months and those that can be given to pets of all ages.

Ease of administration

Unfortunately, not all flea sprays are easy to administer – despite their straightforwardness. Some spray bottles are difficult to maneuver if you are using them on a large dog or to treat affected areas such as carpets or furniture. Go for 360-degree nozzles for faster and noise-free administration, or if you are treating outdoor space, hose-attachable nozzles.
