As a pet owner, there’s no escaping the fact you’ll have to deal with the issue of fleas and ticks at some point in the year. And let’s be honest, without solutions like the best flea collar for dogs, these parasites can be a pain in the neck. 

I’m talking about a frustrated and miserable dog, the possibility of a full-blown pest infection in your house, utter discomfort for you and your family, you name it.

Luckily, you have a myriad of options to choose from, but not all pooches take well to the more popular options of flea treatment like spot-on products, sprays, or tablets. 

Flea collars, on the other hand, barely get any resistance from dogs because of their simplicity. They work for just about any dog, including those that are not too enthusiastic about other flea treatment alternatives. 

My guess is that you want to know which flea collar will bring your dog (and you) that much-needed relief. Because there are those that won’t work, however expensive they are. These collars can also be used together with bark collars, so in case you use one – know it’s a possibility!

Well, that’s what this review and guide is about, and to start you off, here’s a quick look at what I found to be the most effective flea and tick collars for your pet, taking into consideration the type, versatility, ingredients, and other factors.

Important Features To Consider When Choosing The Best Flea & Tick Collar For Dogs 

Pet parents opting to use dog flea collars may prefer the chemical versions or a natural one. There are also other crucial features to consider when buying a dog flea collar:

Natural Vs. Chemical Flea Collars

Most chemical flea collars tend to be more effective if you’re looking to kill adult fleas or larvae. Reading the label on the flea collar correctly will help you to know whether the chemical flea collar option will actually kill an infestation, kill larvae, or do both. Some chemicals will accomplish neither. 

Chemical flea collars should be handled with care, and you should wash your hands after handling the collar. The chemical is not meant to be ingested by your pooch and should therefore be fastened properly to prevent any accidents. 

Natural options for flea collars are often made from essential oils which are natural plant extracts. Pyrethrins are also effective flea killers while at the same time are known for their safety for humans and domestic mammals. This ingredient is extracted from chrysanthemum flowers. 

Nonetheless, flea and tick collars for dogs reviews from doggie parents seem to suggest that the chemical flea collar options are more favored due to their effectiveness

Repellents Vs. Pesticides

If your dog has not already been infested with fleas, it makes sense to use a repellent, as this can ward off any fleas trying to make a meal of your pooch. 

However, if your canine buddy is already suffering from an infestation of fleas, you want to get a flea collar that has a strong pesticide capable of either killing adult fleas or sterilizing eggs and larvae so that the fleas cannot reproduce and will eventually die out. 

Water Resistance

Be sure to choose a water-resistant flea collar so that the effectiveness of the collar is not compromised in wet conditions. 

Size And Adjustability

Since the flea collar will likely stay on your pooch for extended periods of time, it is important to choose a flea collar with good adjustability and one that fits your dog’s physical size, ensuring comfort while reducing any chances of rubbing. 

Protection Period

Today, you will find flea collars with extensive longevity, offering protection of up to nine months. This gives you options, depending on your needs. 


Since every pet’s needs vary, a pet owner will have to gauge whether they need a flea repellent or flea killer. In the event that you have an infestation, then you may need to go with a more potent flea collar option for maximum effectiveness. 

Tick Protection

To save on cost and time, it does work better to get a flea collar that repels both fleas and ticks. So, be sure to check if the flea collar that you get works on both for the sake of your dog’s comfort. 

Who Should Buy A Flea Collar? 

As a pet owner, you will have to contend with fleas at some point. And if you are one of those pet parents who prefer a low-maintenance option, then a dog flea and tick collar is likely to work well for you. Most dog collars remain effective for three to nine months, ensuring you do not have to worry about fleas on your pooch for that duration. 

When it comes to using flea and tick collars for dogs, all you have to do is simply get the dog flea collar on your pooch’s neck, and let it go to work getting rid of pesky fleas and ticks. 

In case your canine buddy has had reactions with other flea deterrents like spot treatments, or just doesn’t like taking tablets, dog flea collars are a good alternative because of their simplicity and ease of use. Just put it on your dog, and forget it! 

However, if your dog is prone to irritation from wearing a collar for too long, then perhaps this option might not be the best for your pooch. You can try flea shampoos or go ahead and remove the ticks or fleas manually, as shown in the video below:

How These Collars Work

It seems almost too good to be true, that you can actually get rid of fleas on your furry buddy by simply getting her to wear some of the best flea collars for dogs. But it works!

The best flea and tick collars for dogs can kill or prevent ticks and fleas in several ways. Some flea collars kill fleas through chemicals such as:

  • Amitraz – An ingredient commonly found in flea prevention products 
  • Pyriproxifen – This ingredient does an excellent job of targeting flea eggs and larvae. It sterilizes them, making them unable to mature and effectively disrupting the life cycle of fleas
  • Propoxur – An ingredient that is highly toxic but incredibly effective. It causes the fleas’ nervous systems to break down within 24 hours of exposure. A collar with this ingredient should be handled with care, and your pooch should not be allowed near children while wearing a collar containing this ingredient. 

For doggy parents who are not too keen on using flea collars with chemicals, there is always an option of using flea collars that contain natural flea killing agents such as essential oils or pyrethrins. It should be noted that chemical flea collars are generally more effective than their natural counterparts. 

In the case of flea collar repellents, both chemical and natural flea collars work by emitting a gas or scent that repels pests. Flea killing collars work in two ways: one is by slowly releasing a formulation that seeps into your dog’s fat layer. In this case, a flea would have to bite your dog for the toxin to take effect. 

The second method is that the ingredients are gradually released by the flea collar and spread on your dog’s body by way of her natural skin oils, killing ticks and fleas on contact even before they bite. 

So when buying a dog flea collar, be sure to read the label properly so that you know whether you are buying a chemical-based flea collar or a natural one and how to properly handle and apply it for everyone’s safety.

Can You Use These Collars For All Dogs?

When it comes to special cases such as puppies, pregnant dogs, nursing mother dogs,  and senior doggies, I always recommend that you check with your vet first. 

Generally speaking, flea collars can be used on pups, but if the flea collar contains ingredients such as Pyriproxifen, your pups should be more than seven weeks old. Again, read the label and packaging for instructions.

Ingredients such as pyrethrum, linalool, and limonene are gentler and may work with pups that are four to six weeks old. 

Before using a flea collar on the any of the above mentioned dogs, first check with your vet in order to ensure that you are using the right product for your pooch’s special needs. 

Can I Use A Cat Flea Collar For My Dog? 

Using a cat flea collar on your dog, or vice versa, is not recommended. This is for the simple reason that your dog and cat’s physiology are completely different. What works for one may not work for the other. 

The ridding of fleas may be rendered ineffective or even harmful due to overdosage or under dosage when you use a cat flea collar on a dog or the other way around.

So, be sure to specifically buy a flea collar that was made for your cat and one that is specific to your pooch in the event that you need collars for your both.


Fleas and ticks are no doubt every dog and dog parent’s nightmare. They are not just a nuisance for your pooch; a dog with fleas can easily infest the whole house as well. So, it is in your best interest to find a solution that works for your pooch’s comfort and your own peace of mind. 

Flea and tick collars are a great, hassle-free, and low-maintenance option that effectively kill fleas at a relatively low cost. The Seresto Eight-Month Flea & Tick Prevention Collar, the best overall in this review, would be a great option to start with because of its longevity, versatility, quick action, and the impressive feedback from pet owners already using it. 

For pet owners who want a solution that offers the best value, is a natural repellant, or is as effective on puppies as it is on adults, the rest of the collars on this list have you covered.
