It is easy to use and can be applied with leash collars ( identification dog collars) but leave your pooch just as comfortable. Combined with a yard and home flea treatment, Seresto flea collar will provide a long-term remedy against flea infestation. 

Seresto flea collar will repel and kill fleas simply on contact and thus the bugs won’t need to bite the cat’s skin first. It’s odorless, water-resistant, non-greasy and they’ll exterminate fleas plus ticks on your dog for 8 months. 

The flea collar will slowly and in small quantities release the active ingredients, Flumethrin and Imidacloprid, to spread the whole dog’s coat, with the help of your dog’s natural oils. Also, the collar has an excellent breakaway release system that’ll release if the dog is trapped. 

Imidacloprid breaks the life cycle of the pesky fleas by killing flea larvae and adult fleas alike. On the other hand, Flumethrin will repel and kill the adult fleas and ticks. You can install reflect clips on the flea collar to assist with visibility of teh dog at night time. 

But, the fleas don’t have to bite your pooch to die – it kills the pesky bugs immediately on contact. The collar eliminates the itching, distress, or spread of infections that would come with flea bites.  

Seresto flea collar has a 2-6 hours knockdown effect to kill the fleas and ticks biting and irritating your dog. Hence, the ingredients will kill the fleas quickly to stop spreading infections or laying more eggs.

Rolf Club 3D is created from natural oils that are extracted from plants, and thus it’s non-toxic to the dog’s or cat’s skin – what vets call hypoallergenic and safe for sensitive and allergic skin. But, after applying the flea collar, remember to inspect your dog (maybe within 6-96 hours) for an unwanted skin reaction.

Luckily, this budget-friendly collar will give your dog roughly 8 months of flea extermination. The blend of natural ingredients like citronella and eucalyptus makes it largely safe for kids. 

The natural ingredients make the flea collar very eco-friendly and won’t be harsh on the environment. The citronella and eucalyptus won’t be harsh on your skin or that of your dog but will kill fleas immediately on contact. Also, the eucalyptus oil will help cool down the pain that is on spot with itchy or irritated skin mainly due to flea bite marks. 

GORAUL Flea Collar may also be considered to be a one-size-fits-all flea collar that’ll be suitable for dog breed or size allowing a snug fit. However, as noted above, you can also purchase the appropriate sizing for your specific dog but adhere to the product label instructions. Check whether the dog or pupies have skin irritation or hair loss, which could signify time to replace the collar.  

GORAUL Flea Collar comes in a 25-inches length and its also highly adjustable to fit either the large-, medium- or small-sized dogs. Cut off then collar length that’s suitable (but leave some inches) and place the excess in the kennel so that the dog doesn’t chew it. Further, don’t let kids play with the collar you’ve cut off. 

Ensure that you don’t choke your dog when fitting the collar – particularly if you make it too tight. Notably, after fitting the collar, you need to easily fit 2 fingers between the dog’s skin and the flea collar. Further, ensure you check regularly on the flea collar’s fit and tightness particularly for the rapidly growing puppies.

5. LOVATIC Dog Flea Collar 

First, Lovatic is an excellent firm when it comes to making pet products. I would dare say that I’ve followed how greatly they improve their products and offer excellent customer care. So, it’s not a surprise that they’ve produced a great dog flea collar – the Lovatic collar.

Next, Lovatic flea collar is designed wholly from natural active ingredients. Therefore, the flea control collar is described as being 100 percent hypoallergenic, which means that it’ll be safe for all your dogs regardless of their breed.

Lovatic flea collar will offer exceptional convenience in controlling fleas and save you a lot of time. In addition, Lovatic will leave a sweet smell on your dog and the house in general. Therefore, you can do away with the product leaving your dog with a greasy coat and pungent smell. 

Also, Lovatic flea collar does not promote air, noise, or water pollution – which makes it qualify to be an eco-friendly dog flea collar. The collar does not release chemicals or dangerous gases to your environment. Equally, it won’t be toxic to your dog or cats in the surrounding. 

Lovatic came as an excellent solution for repelling and killing lice, flea, and ticks. Previously, as noted above, I had tried using options like lemon and shampoo. However, Lovatic and other flea collars gave me longer services in controlling the pesky fleas on my dog. 

Lovatic flea collar has a buckle and loop design that you’ll easily adjust until it fits your dog – which ensures you don’t shock or strangle your furry friend. The active ingredients in the flea collar are releases slowly over 8 months to kill both adult fleas and their larvae.

I’ve reviewed cheap flea collars above but this HARTZ Ultraguard wins for being highly budget-friendly but equally as effective and thus suitable for DIY flea control on your dog.

In addition, the collar is versatile as it’ll also kill flea eggs, their larvae, and ticks too for 7 months. This collar will offer full body protection from these pesky little creatures- from the head, toes, to tail. 

The collar is designed to fit dogs and puppies with necks that measure up to 26”. It comes in different sizes, so whether yours is a large-sized dog, medium-sized, or a puppy (over 12 weeks), there is a perfect fit for each dog size. The manufacturer, however, does not recommend using this collar for puppies under 6 weeks.

The HARTZ Ultraguard Flea Collar for dogs is a simple yet incredibly effective dog flea treatment that is easy to use, completely safe, and highly affordable. It might not be as effective as the top two collars we’ve reviewed but for that such a low price, it’s well worth it!

7. Virbac Preventic Collar – 25″ -1 Single Collar

A tick infestation can quickly have an impact on your dog’s health. Ticks are nasty bloodsuckers and disease transmitters. Besides their infectious bites, dogs with ticks can become extremely uncomfortable with endless itching and scratching.

Virbac Preventic Tick Collar is a veterinarian-recommended dog collar that does a great job killing, detaching, and preventing ticks from attaching onto your dog’s skin for a period of 3 months.

The collar contains Amitraz, a very powerful active ingredient that offers continuous tick protection for 3 months.

Perhaps the only disadvantage with this dog collar is the fact that it’s not designed for fleas- you’ll need to purchase a separate flea treatment. The manufacturer, however, says that it works best when used alongside a topical flea/tick product.

The Virbac Preventic Dog Tick Collar is designed to fit dogs with necks measuring up to 25 inches and weighing up to 60 lbs. However, it can be easily adjusted to fit small-sized dogs.

Buyer’s Guide – What’s a dog flea collar?

Flea collars are pet gadgets that are installed around the dog’s neck to either repel or kills fleas. The flea collars are made from either from cloth bandana, leather, or plastic resins.

  • One collar produces ingredients that seep into your dog’s layer of fat, and thus the fleas must bite the dog to be exterminated.
  • The other collar produces ingredients that’ll use the dog’s skin oils to spread all over its body, and thus kills the bugs simply when they get into contact.

Do I really need the Dog Flea Collar?

The first thing we must tackle is where we need a dog flea collar anyway. Well, flea collars will be helpful for any dog owner who has or suspects a flea infestation on their dog.

In addition, flea collars are budget-friendly and low-maintenance flea treatment methods. For example, you can just install the flea collar on your dog and you’re done with the dog flea problem for about 3-7 months.

Next, flea collars will be great if your dog has sensitive skin or allergic reactions to other flea control options such as flea shampoos. Also, some of our canine pals may tend to dislike taking flea control tablets.

However, these flea collars might not be suitable for all dogs. For example, check within the next few hours and days, after installing the flea collar on your dog, whether the pet experiences some skin irritation, hair loss or skin sores.

In such case, your dog won’t benefit from the flea collar and thus you must remove it immediately or contact your vet.

Any side effects of using flea collars in dogs?

Some dogs (albeit few) may experience side effects, such as skins sores, due to using flea collars. The symptoms of such side effects include losing hair/ skin soreness around where you’ve installed flea collar, excessive scratching/ irritation, wheezing, lethargy and vomiting.

Allergic reactions mainly happen when the dog flea collar has the following insecticides as their active ingredients: carbamates, organophosphates, pyrethrins, and mitraz. If any of the above side effects occur, ensure you uninstall the flea collar from the dog’s neck and take the dog to the vet promptly.

Your vet may encourage bathing the dog using some mild detergents, or applying some antihistamine on the pet’s skin to reduce itching or swelling. However, most dogs will experience some mild symptoms like itching that won’t progress to more adverse health effects.

Will flea collars poison my puppies?

Despite the hype, these flea collars are just one type of over-the-counter flea solutions. This implies that no vet will be supervising its administration or installation, which might escalate the probability of allergic effects.

Sadly, flea collars may have an unsuitable insecticide combination or dosage for your puppy. In addition, some active ingredient could even trigger skin sensitivity or allergies.

Puppies may innocently chew the flea collars that might have harsh and dangerous insecticides and chemical. Such ingestions may lead to organ failure, reactions in their immune system, or even cancer. Ensure to always read the product label instructions for the flea collar on the appropriate age for the puppies.


And that’s a wrap guy! These are some of the best flea collars for dogs you’ll find in the market and the fact that they are all incredibly affordable makes flea prevention and control much less of a hassle.

And the good news is that they offer months-long protection, keeping your furry friend comfortable and safe.
