Summer can be a great time to get out there and explore with your dog. Many families have time off from work and school, and what better way to enjoy time together than to head out for an adventure? A beach trip, a hike, a vacation to a nearby town or a simple trip to the park are all excellent activities where the family dog can come along too. It is warm, it is fun, but with that warmth and the good time come the creepy crawlers – the fleas and the ticks.

Fleas, and especially ticks, thrive in warm weather, and nothing ruins a great day out like coming home to realize your dog has gotten infected. Fleas and ticks cause problems year-round in some places but tend to step up their game during warmer months. It is absolutely essential to invest in protection for your furry best friend, and you might want to consider a dog flea collar to keep those unwanted visitors off your dog’s body.

Note from our DVM, Sara Ochoa:

“Most flea and tick collars do not work on dogs in my area. I do have a lot of success with the Bayer Seresto collar.
When putting the collar on you have to make sure it is tight enough to come in contact with the skin. The rule I use is to be able to put 2 fingers between the collar and the dog’s neck. You do not want it to be to tight as it will cause breathing or even skin issues. Also if the collars get wet and stay wet this decreases their potency.
So, for the dog that spends all their time in the swimming pool, pond or ocean the collars will not last the 6-8 months that most advertise. “

Flea Collars For Dogs Buyers Guide

What is the best flea repellent collar, then? Many of the flea treatments we have reviewed are very similar, which has a lot to do with companies having adapted to the advances of dog product related science, but also to their customer’s needs and requirements. Nobody wants to have to turn to poison and hazardous products to fight off ticks and fleas, and luckily the industry has listened and started producing a wide range of natural options.


The function of the best flea and tick collars for dogs will eliminate existing flea infestations (though a bath with tick and flea shampoo might be necessary for difficult cases), as well as to prevent fleas for wanting to climb up on your dog during walks and when out playing. Ticks and fleas are everywhere, especially during the summer months, and sometimes it does not matter how careful you are with letting your dog stick their face in bushes and tall grass – those critters will find their way!

A flea collar uses either chemicals or naturally repelling active ingredients to keep bugs off, either by killing fleas and ticks upon contact, or by using herbal smells (such as Lavender) which they simply don’t like.

Ticks and fleas aren’t just unpleasant, they can be dangerous as they – and especially ticks – are known to spread disease (with Lyme’s Disease being on example). Some of the top-rated flea collars for dogs will also help fight off mosquitos, which can be great for camping trips and hikes. Mosquitos spread heartworm, which can be deadly if left untreated.

Natural vs. Regular Flea Collars For Dogs And Puppies

Today we see more natural flea treatment products on the market, which is a result of advanced technology and overall greater knowledge.

Old flea and tick dog collars could cause burns and irritation on your dog’s neck, and some even more severe symptoms were reported and ultimately traced to the use of flea collars. Allergies were common, forcing dog owners to choose between protecting their dog from ticks and fleas with a tick and flea collar, or to protect their dog from the repellent collar itself and risk a bug infestation. Luckily, times have changed, and products now use natural repellents like Lavender and Citrus; both known to ward off unwanted insect inhabitants.

There are flea & tick treatments that are 100% natural, and others that have some natural components, but it is recommended to always look for the most natural product (such as those suggested in the list above) when choosing anti-bug method, and especially when looking for the best flea and tick collar for puppies, as they are more sensitive than adult dogs.

Flea Collars & Water

There was a time when flea collars should not be used in- or around water, as it could either release harmful fumes or stop working properly once having gotten wet. This had to do with the materials used to make them, and many modern flea collars are perfectly safe to use both when it rains and when the pup wants to go for a swim in the ocean.


Dog wearing flea and tick collarHow long the effect lasts can vary greatly from product to product but tends to be something between 4 and eight months.

This means the dog can wear the collar for preventing tick & flea infestations safely during this time and longer, but maximum effect can only be guaranteed for the timeframe specified.

Something to consider a guideline, yet not a rule, is that the more natural the tick collar for pet pals – the shorter its lifespan.

Harsh chemicals can make a flea collar and its effects last a very long time, but do you really want potentially harmful materials anywhere near your dog? Yes, you might have to buy a new dog flea and tick collar more often if you choose to go natural than if you go with a different type, but it might be worth it considering the favor you are doing for your dog and for their overall animal health.

Will flea collars kill existing ticks and fleas?

Some claim they will, and some won’t. The best thing to do if your dog already has adult fleas and/or ticks is to bathe them properly first with a natural anti-tick and flea shampoo, to get most of the infestation dealt with before applying the collar.

What flea collar to get for a puppy?

Did You Know?

A flea can only live for a few days without a host, but can live for 2-3 months with dog food available, and up to a year and a half in ideal conditions (with food, the right temperature etc. etc). This means that without the proper preventive actions – you might be stuck with those blood suckers for a lot longer than you’d like. A flea repellent collar kills them or drives them off before they can lay eggs and larvae, which prevents an unpleasant flea infestation. Find more about getting rid of fleas with the RSPCA.
