Picking up fleas and ticks is a pretty common occurrence for dogs, and all that scratching can seriously irritate them and you, but with our list of the best flea and tick treatments for dogs, you can find the perfect option to rid your furry friend of these pesky pests and relieve their itching quickly.
But before you just throw a random option in a cart, there are a few things to consider when shopping for flea and tick treatments. First, decide whether you’d like to use a topical option that’s often applied between the shoulders or an oral option that makes dosing as easy as tossing them a treat.
Know how much your dog weighs because that’s an important factor in getting the correct dosages. If you opt for topical treatments, look for products with fipronil and methoprene as their active ingredients, as both are highly effective in treating fleas and killing flea eggs. Plus, you can always get advice from your veterinarian if you’re just not sure. But chances are, their recommendation is already included in our list of the best flea and tick treatments for dogs!

Frequently Asked Questions
Fleas and ticks are nasty bugs that plague pets and their parents, but if you’ve never dealt with these little bloodsuckers, here are a few things to know.
How Will I Know If My Dog Has Fleas And Ticks?
To check if your dog has fleas or ticks, rub your hands through their fur, making contact with the skin, and feel if there are any bumps and if the skin looks red or irritated. Check for “flea dirt,” black, flaky specks on the skin that are left behind after a flea takes a blood meal—yuck! Fleas are often easiest to spot around the dog’s tail base, while ticks are trickier. They like warm, dark spots such as in the ears, under the joints, and between the toes.
Another sign of fleas and ticks is constant scratching, licking, and chewing. Also, when you see your dog concentrating their efforts on a particular spot, jump in real quick and comb through your pup’s fur to find the offender. Fleas can be easy to spot on lighter color fur or in spots where hair is thinnest. 
Are Fleas And Ticks Dangerous For Dogs?
Fleas and ticks may look tiny, but they can irritate and annoy your furry friend. The constant licking and scratching can create sore hotspots and even broken skin. Plus, fleas can cause terrible allergies, while ticks carry diseases like Lyme and Ehrlichiosis. And the longer your dog has fleas, the bigger chance you’ve got for a household infestation that can see fleas nesting and burrowing in blankets, carpets, beds, or linens. Then you’ve got an even bigger problem.  

Can Humans Get Fleas From Their Dogs?
Yes, humans can pick up fleas from their dogs, but it’s not as critical for us as it is for our pets. We don’t have fur for fleas and ticks to hide in, so they’re easier to spot when we feel their bite. Though we don’t have fur, we do have hair, so ticks can hide amongst the follicles and even attach to the scalp. Got the heebie jeebies yet? 
What If Fleas Are Left Untreated in Dogs?
If fleas are left untreated, they can cause damage that results in severe skin problems. Unencumbered, fleas will keep breeding and hatching in your dog’s fur, getting fat and strong off their blood. Such an infestation will make your dog miserable. Fleas can also cause serious allergies in some dogs, and all the scratching and chewing can lead to painful hotspots and skin infections. Ticks carry a wealth of diseases, most notably Lyme disease, and when your dog is left to be a buffet for these creepy crawlies, they’re at greater risk of catching one. But flea and tick treatments can rid your pup of these irritating invaders and reduce their chance of illness.
To bring a bit of simplicity to your life, we’ve combed through the competitors to bring you this list of the best flea and tick treatments for dogs.
