Choosing the Best Flea Collars for your Dog

Flea Collar Dogs

If you’ve ever had to deal with an infestation of fleas on your dog (and in your home, since they’re not fussy about where they breed and multiply), you’ll know that prevention is always way better than cure. While you can use topical treatments to eradicate fleas, it is often easier to choose a flea collar for your dog to wear.

There are several things to think about before purchasing a collar. We’ve covered the most important elements below, each of which were taken into account when recommending the best flea collars above.

Is the flea collar approved by vets?

We’d love proper flea collars to be cheap, but the ones that are don’t tend to be impregnated with anything that works against the nasties you are trying to avoid. Most reliable flea collars need veterinary approval or must be bought on prescription. That is a sure sign you are buying something powerful enough to work.

Fleas only or fleas and ticks?

If fleas are frustrating, ticks are plain nasty. While only a small percentage carry Lyme disease, they carry all kinds of other diseases too. They are also hard to remove once they latch on. If you can avoid your dog getting bitten by a tick, it’s best to do so.

Some flea collars also carry protection against ticks, so if you live somewhere with a prevalent tick population, this might well be the best option. It’s also good to consider a flea and tick collar if you go on holiday somewhere that is known for its ticks. Anywhere with lots of wild roaming deer or sheep, for example.

How long does the collar last?

Some collars are more powerful than others, lasting far longer in the process. most should be fine for at least three months, but some last for around eight months.

You can expect to pay far more for a longer lasting collar but do work out the monthly cost before raising your eyebrows at the price. You may be surprised. You also need to factor in the total cost of the usual protection you use, whether that is tablets or pipettes delivered to the back of their neck.

How does the flea collar work?

This might sound like a weird question, but they do not all offer the same degree of protection against ticks and fleas. Some collars will kill them if they bite your dog, while others will die the moment they land on your dog. The latter is our preference, especially with ticks. If you have ever tried to remove a tick once it has latched on, you’ll know how difficult it can be to successfully do. Proper tick tweezers should be used, otherwise the head and/or mouth parts can remain inside your dog under the skin and cause an infection. Even then, it is quite a challenge to do correctly.

With a collar that kills them immediately and/or deters them from landing on your dog to start with, you won’t need to worry about this issue.

Which chemicals are in the flea collar?

Not all collars use the same formulas. For example, the top-selling Seresto collar has a combination of flumethrin and imidacloprid. Those names may not mean anything to you, but they are viewed as safer for your dog than alternative chemicals that are impregnated in other collars. There are concerns about collars that are based on something called TCVP (tetrachlorvinphos). Some animals have had nasty reactions to this when exposed to it, so you may want to avoid anything containing TCVP.

Is the flea collar water resistant?

You might think this is only relevant if your dog loves swimming. It would be a greater concern if this is the case, but all dogs get wet. Sure, you can take off the collar when you bath your dog, but you want to be sure it is good enough to withstand rain showers too, especially when it is designed to last several months.

What size flea collar does your dog need?

Most flea collars are available in several sizes. Some of the cheaper ones may be available in a ‘one size fits all’ option. This typically requires you to fit the collar and then trim it to get rid of any overspill. We prefer the sized ones, as it simply means you need to measure your dog’s neck and get the correct size for their needs.

Would you rather get a natural flea collar?

There are some natural products on the market that avoid the use of chemicals and instead use natural ingredients to ward off fleas and ticks. One thing to bear in mind with these is that they do not kill fleas or ticks but work instead by repelling them. As you might guess, some are more effective than others at doing this. If your dog already has fleas, it may not work as well as you would like.


These collars are often a more convenient alternative to other methods of repelling and killing fleas and ticks on your dog. A collar that lasts several months means you have the protection your dog needs, without remembering to apply those pipettes or administer medication every month. You should set a reminder on your phone though, alerting to you when a new collar is required. It is very easy to forget to replace it when it lasts three months or more. That could leave your dog exposed to the possibility of attracting the very thing you are trying to avoid. If you remember when to change them though, flea and tick collars are the perfect solution for avoiding the nasties.
