Characteristics To Look For

Start by figuring out which features and characteristics are most important when choosing your dog’s flea collar. You should keep all of the following in mind.

  • Length Of Collar

The very first thing you need to consider when searching for the best flea collars for your pooch is how long it needs to be. Tiny breeds will need much shorter collars than huge breeds. The collar should always fit your pooch properly, providing enough slack for comfort without too much extra space that causes it to fall off. Some collar say they are for all sizes of dogs because of their extreme adjustability. Others are designed for a specific length range.

  • Weight Limits

In addition to mentioning the length of the collar, you will notice that some collars have a designated weight range. Part of this is to ensure that you choose a collar of the right length for your pooch. The other aspect is controlling the dosage of the flea treatment. The treatment needed for a large dog would overpower a small breed, leading to potential health issues.

  • Natural Or Chemicals

The most common type of flea collars for dogs will be those that are chemical-based. These contain insecticides of some sort, preferably a combination of those that will kill adult fleas with those killing eggs and larvae or at least inhibiting their growth. You should only opt for a chemical-based flea collar if your pooch is an adult and healthy because of the insecticides and their toxicity.

Some people prefer to get their dogs a flea collar that uses herbs and oils to kill and repel fleas and other insects. These are completely safe to use for your pet and better for the environment since there is no need to produce harmful chemicals or worry about runoff. Some natural collars, however, won’t be as effective as chemical-based ones or may need to be replaced more frequently.

  • Ultrasonic

Although less common, you can also find ultrasonic collars which emit an ultrasonic sound that repels the insects without annoying or even impacting your dog or you. These collars rely on batteries to function and unlike those containing herbs and oils or chemicals, they must be combined with flea drops for effectiveness.

  • For Dogs

Anytime you buy a flea treatment for your dog, including a collar, ensure that it is designed for canines. There are also flea collars for cats, so read the instructions carefully.

  • Age Limits

Pay attention to whether your pooch is old enough to safely use the flea collar, particularly if he is still a puppy. Most flea collars will be safe for those who are at least eight weeks old, but this can vary so look at the product description.

  • How Long It Lasts

Don’t forget to pay attention to how long the repelling effects of the collar will last. Not only do you need to be aware of how frequently to change the collar, but this can affect its value. After all, it is worth paying a bit more for a collar that lasts twice as long as you will save money in the long run.

  • Waterproof

The best flea collars for dogs will be waterproof, at least to some extent. You want to be able to keep the collar on your pooch when he goes for the swim or you two go for a walk in the rain. Many collars will even remain effective following baths; you just need to confirm this is the case with your chosen item.

  • Smell

Some of the insecticides used in flea collars can have an unpleasant scent so ensure that the collar you select doesn’t smell bad or has no odor at all. In addition to looking at the product description, you can get this information from reviews.

  • Pests Killed

Ensure that the flea collar you select takes care of all the pests you want it to. Some will only target fleas while others only target ticks. In addition, you should confirm that the chemicals used kill young fleas as well as adults.

  • Avoid Extremely Cheap Collars

While you do want to save money on your dog collars, you should only trust ones that cost at least $20 or so. Those that are even more expensive than this tend to be more effective, safer, and from better brands. Opting for a collar that is too cheap will have one of two negative effects: either it won’t work at all and your pooch will become infested with fleas or it will rely on insecticides that put the health of your canine at risk. Buying a poor quality collar can lead to an allergic reaction or even poisoning due to intoxication. Because of this, it is much better to pay a bit more and get a high-quality collar.


With your purchase of a best flea collar, your dog can experience relief from fleas without having to worry about using a spot treatment or getting him to swallow a pill. Your pooch will appreciate the ease of a flea collar and not even realize you are protecting his health.
