Flea Spray For Dogs Buyer’s Guide

Being a mommy or daddy is a big responsibility, whether it’s to our children or fur baby. Seeing our sweet pooches in any sort of physical discomfort can be heartbreaking. The best flea treatments for dogs should be safe, that’s always the first concern, followed closely by convenience, and of course efficiency. Let’s take a look at what to look for when selecting a flea spray for your canine.

What is Flea Spray?

Simply put, flea spray is a spray that is able to offer flea control and prevention. When you use flea spray, you are killing all the living fleas in the area and stopping the eggs from hatching, thus preventing further infestation. You need to get rid of fleas in every stage of their lifecycle to make sure they don’t return. All you need to do is the point, aim, and spray!

What to Look for When Buying Flea Spray?


Flea treatments must contain some form of pesticide, this is how they are able to deal with the pesky little critters. The EPA approves of all pesticides used in flea treatment, but some can still cause members of our family some serious harm, furry or not.

Try to get mostly natural ingredients and avoid the following:

Tetrachlorvinphos – Overexposure to this insecticide could cause nausea, dizziness, and confusion. Serious cases could be fatal.

Pyrethroids – Humans exposed to this can experience numbness, itching, burning, stinging or tingling.

Pyrethrin – This chemical affects cats more so than dogs and humans. But just to be on the safe side, avoid this if you can.

Other than the ingredients, looking at their functions is also helpful. Most sprays will kill, and prevent fleas and ticks and some may prevent other pests from making a home in your home. The label will usually tell you all the safety precautions to take and how and where to best use the spray. Make sure you always err on the side of caution.


Whether you have a flea infestation or not, flea spray can come in handy. They have preventative uses and are fast acting against existing fleas. Because they are so easily administered, flea sprays are a go-to when it comes to flea infestations. With a simple spray bottle, you can reach all those hard to reach dark places where the fleas or ticks fester and grow and wipe them out in one fell swoop.

We’re going to remind you again that your pet’s safety should be your first consideration, not the price or the quantity. Read the directions and content label carefully before making your purchase, and always err on the side of caution. Good luck to you, and let the takedown begin!

Expert Tip

Fleas are so small they might be hard to notice before your dog shows signs of itching and scratching. They are smart and insolent little critters that hide where it’s hard to reach for your dogs. To check, look near the base of your pet’s tail, and sift through the fur on their neck, belly, and chest. Any sort of warm and hidden places can be a good home for these pests. Look between their toes as well for these creatures.

Did You Know

Keep your home clean. These pesky pests like to live in carpeting or rugs, and any kind of place that traps dust. Vacuuming your home often can help prevent them. When your pet comes home from a day out, run a comb through its fur quickly to remove anything they may have picked up along the way, and shave or clip your dog using dog grooming clippers in the summer to reduce the risk of fleas and stay pest-free.
