Buyer’s Guide

When it comes to purchasing products for your dogs, it is not only challenging to figure out the best ones to buy, but it can be challenging just to figure out what you need for your dogs. Now that you are aware of some of the best flea collars on the market this year, you may want some guidance for how to pick one out. Below we provide you with a buyer’s guide telling you a little more about how flea collars function, the benefits of using them instead of other preventative measures, and what to think about when these need to be on your next shopping list.

How Do Flea Collars Work?

Flea collars are quite simple in their methodology. They work with compounds, whether chemical or natural, to create overall protection, either hovering around the dog or actually on the dog’s hair and skin.

The flea collars release whatever compound the collar was made with intermittently. This function is what gives the collar a certain lifespan, anywhere from four to eight months.

There are two main kinds of collars that help to protect your dog. The first type functions more as a preventative measure. It releases scents or chemical compounds into the air around the dog, generally undetectable by humans and the dog itself. This release stops fleas, ticks, lice, and even mosquitos from being attracted to the dog and repels them.

The primary con to this first type of collar is that it does not help if the dog already has an infestation of fleas, ticks, or any other similar pest. It may be natural and thus have less adverse potential side effects, but it is not the way to go if you need to stop an infestation from becoming worse.

The second type of flea collar is a killing collar. Once unwrapped and fixed on the dog, these collars start to work within the first two days. They release their chemical compound onto fur around the collar. The natural oils from the skin of the dog take the compound throughout the rest of its body. These chemicals kill on contact. Once they touch any flea or tick, including any life stage of these pests, they immediately poison them, and the parasite dies.

The unfortunate facet of these collars is the potential side effects that come with effectively coating your dog in unnatural chemical compounds. Although these collars have to get tested for safety, there are still risks involved when using them. If your dog has very sensitive skin or specific health problems, ask your vet about using a particular collar to protect your dog.

Benefits of Using Dog Flea Collars

Although the benefit of using a flea collar may seem obvious to some, others might not grasp all of the beneficial aspects involved. Not only do flea collars help to protect from flea infestations, but they also put up a shield against several other harmful pests like mosquitos, ticks, and lice.

There are benefits when it comes to using flea collars over other preventative measures as well. Using spot treatments can be frustrating due to the frequency involved. Many of them need to be applied every month without fail to offer continuous protection. Others may need to be applied weekly. When using flea collars, you have options to consider that offer protection for anywhere from four to eight months reliably.

If your dog has sensitive skin or allergies, flea collars are even more worth consideration. There are some products, including some of the ones we have listed above, that are hypoallergenic. We often think of dogs being hypoallergenic regarding the human’s allergies to their skin or shedding, and dogs may also have allergies. Keeping harsh chemicals or certain compounds off of their skin may stop them from developing skin infections or harmful amounts of excessive scratching.

Finally, using a flea collar instead of having your dog take tablets is generally judged as a safer option. It is difficult for scientists to determine precisely how extensive the internal effects of ingesting certain chemicals are on a dog. To mitigate this risk, keep the solution on the outside.

Considerations When Buying a Flea and Tick Collar for Dogs


Before buying a collar, be sure to measure around your dog’s neck. This ensures that when you invest in one, it will be sized correctly for your pup. The functionality of a flea collar comes down to the make of the collar. This refers to the size, length, weight, and even the odor that the collar may give off. If you have an aversion to strong odors, be sure to check that the collar does not have these. Unfortunately, many of the natural solutions have strong smells to be effective. They fade quickly but keep it in mind.

Active Ingredients

If your dog has any allergies or sensitive skin, be sure to check what the active ingredients are on the flea collar. By checking the ingredient list beforehand, you alleviate the potential of causing your dog stress or pain upon fitting the collar. Also, consider how safe the active ingredients are for both humans and your dog since it will rest on its fur and skin for months at a time.


Dogs get into a lot of messy situations. This can be funny at times, watching them wiggle their way through a hedge or wind their leash around their owner’s legs. However, you don’t want the investment of a collar to end up being a dud within the first few weeks because your pup is especially hard on it. Read reviews to make sure that the collar lasted for as long as the advertisement says it should.

Water Resistance

Since a flea collar works by releasing chemicals or other compounds into the air or across a dog’s skin, it would be pretty useless if they washed off in the rain or after a muddy bath. Make sure to check that the collar you have an interest in buying is at least water-resistant if not waterproof. This stops one roll on wet morning grass from ruining the collar.


Efficacy refers to the collar’s capability to prevent the parasites that it says it can. There are many proposed solutions and flea collars on the market. Those with high efficacy do a great job deterring pests from occupying space on a dog’s body. It also refers to the extent of the protection the collar offers. For example, does it only protect from fleas, or does it help deter lice, mites, ticks, and mosquitoes as well? Does it stop only certain stages of the life cycles of these pests, or will it kill anything it touches?
