Buyer’s Guide

When it comes to buying the best flea collar for your dog, it can be challenging to know what exactly it is that you should be looking for.

Is the protection period more important than its effectiveness? Does it really need all those soothing oils? 

As you can see, there is no one particular characteristic that makes a flea collar the best to buy. Instead, it’s a combination of various factors that will help you make the best choice for your pet. 

You also need to take into account the stage at which you will be treating the infestation and will need to make a choice based on that before everything else.

Once you know what stage you’re dealing with, you can narrow down your search to ensure that you are fully protecting your dog and providing it with the right treatment.

We’ve put together this handy buyer’s guide which will point you in the right direction and give you all the tips you need to make sure that you choose the perfect product for your precious pooch.


Having to frequently purchase a flea collar isn’t an ideal scenario, but luckily there are products that can cover you for up to 8 months at a time and in some cases, even longer. 

You may think that changing your dog’s collar more frequently ensures that they receive maximum protection, but that’s not always the case.

With slow-releasing formulas and new technology, there are many collars that maintain a high level of protection throughout their wear. 

A factor that might come into play with the protection period is water, which can sometimes reduce the number of months the collar is effective. 

You also want to find something that gets to work straight away, especially if your pet isn’t yet showing signs of an infestation.

The quicker you’re able to protect your dog from future infestations, the better. 

If your dog already has fleas then this is where you need to be more careful with your selection.

Some collars aren’t as effective if your pet already has fleas, however, some products kill the parasites at all life cycle stages – perfect if your dog has had fleas for some time and may also be carrying eggs.


Knowing how quickly the weather can change and also how fun-loving most dogs are, your collar of choice should also be water-resistant.

This will give you, the owner, the freedom of washing your dog or allowing them to dive into the river without having to worry about removing the collar first.

The only issue with water-resistant collars is that, as previously mentioned, the protection period can be altered if exposed to water frequently so always make sure you check this before purchasing. 


The chemicals included in your dog’s collar are important as they may cause irritation and harm to your pet.

The balance needs to be correct in order for the collar to be effective enough to kill off parasites but remain gentle enough to be kind to your dog’s skin.

Most collars get this balance just right, but some manufacturers may not be putting your dog’s safety first and will use pesticides that are harmful to your pet.

Before you purchase your collar, it’s good to do your research on which pesticides to look out for. 

You should always check for the following chemicals which are considered toxic in high volumes:

  • Tetrachlorvinphos (TCVP)
  • Lufenuron
  • Permethrin
  • Propoxur

Infestation Stage

Different collars are designed for various infestation stages so knowing which stage your pet is at is crucial when it comes to selecting the right collar. 

If your pet is already showing signs of an infestation, then the fleas will need to be eradicated. In this case, your best choice is a treatment collar that would kill any existing parasites. 

However, if your pet isn’t yet showing any signs of an infestation then you would need to look for a repellent collar to help prevent any parasites from setting up home on your pooch.

By knowing which stage your pet is at, you’re able to narrow down your search and guarantee that you’re treating and covering your pet for the correct stage of their infestation.


It’s common to see dogs wearing the wrong size collar, but if this happens with a flea collar then the treatment may not be as successful.

If you have a small pet, buying a collar designed for larger dogs means that it could potentially fall off during playtime leaving your dog exposed to the possibility of picking up parasites.

If you choose a collar that is too small, then your dog is going to feel discomfort while wearing it. 

To guarantee that you have the perfect fit, it’s essential that you check the manufacturer’s size guide and follow their instructions for how to correctly measure your dog’s neck.


Some owners may think that purchasing a collar with a nice scent is a bonus when looking for the right product.

However, it’s good to remember that dogs have an extremely strong sense of smell, so something highly perfumed may irritate and frustrate your pet.

When choosing a product for your pet, it’s important to remember that the comfort of your pet should always come first. 

With many odorless options to choose from, you may find that this is the better option.

Not only will it do its job without any irritation to your pet’s skin, it’s also a good choice for you, the owner, especially if you’re a big snuggler.

The last thing you want when cuddling your pet is a strong chemical scent in your face!
