Dogs are some of the best pets in the business. There's certainly a reason they're referred to as man's best friend. However, one thing that isn't always pleasant about our pups though is the naughty fleas and ticks that can jump onto them. That's why you'll need to be stocked up on dog flea treatments.

Fleas are sometimes unavoidable, especially when interacting with other dogs or exploring the outdoors. You may have been recommended flea treatments by your vet, but it's not always simple to get your paws on effective treatments that really kill those troublesome insects. They irritate your dog's fur and skin and fleas can also make their way into curtains and furniture, which can aggravate us owners too.

Good news - you can get rid of fleas with a variety of treatments - including spot-on, flea collars, flea shampoos, preventer sprays and more. We've hunted down the top flea treatments to buy online right now, so we and our dogs can get some much-needed relief.

What flea treatments are the best for our dogs?

There are a few essential flea treatments that you'll want to become acquainted with as a dog owner. Here's our breakdown of those, so you know what you're getting into:

Spot-on treatments: The most popular of those dog flea options, spot-on removers come in pipettes that you squeeze onto the back of your dog's neck which then kills off fleas and ticks. These are continuous treatments that you'll want to stock up on and can work for weeks. They won't irritate your dog's neck and they won't be able to lick it off because it's at the back of their neck.

Shampoos: Similar to humans with nit treatments, you can use dog flea shampoo to get rid of those little pests. Just lather a dog-friendly flea shampoo onto your dog during bath time and it should kill off any fleas in your dog's fur.

Sprays: Flea sprays are usually used as insect repellent for furniture and your belongings. The clue is in the name, all you need to do is spray over the appropriate areas and fleas be gone!

Collars: Dog collars work similarly to spot-on dog flea treatments because they activate at the neck. However, instead of manually squeezing on your dog, these collars will continuously repel fleas. This may be an effective route to go down if your dog isn't fond of shampoo or pipettes, as they're more likely to be familiar with a collar.

Review: "There are treatments that are a lot more expensive than this 'spot' treatment from Bob Martin. However, price is no guarantee of efficaciousness. In my dog's case, (a 40kg GSD with medium-length hair) the effect has been nothing short of miraculous. He now has a luxurious coat, and more importantly, he no longer suffers from the stress that the infestation of these parasites cause."

If you prefer the method of lathering your pooch up and getting into the nitty-gritty of their coat, invest in a flea shampoo like this Animology option.

I am really precious about what Buster, Topsy and Cleo come into contact with so an all-natural solution that is powerful enough to keep them flea-free is a win-win."
