Purchasing criteria

Throughout this article, we have seen that the use of flea collars is beneficial for pets as they have the power to protect them from infections caused by insects and parasites. But before you go out and buy one, you should know certain factors that will make your purchase safer.

Size and Weight

Just as people are not the same, the same is true for pets. Each animal has different requirements and when choosing a good flea collar you should check whether you need one for small, medium or large breeds and depending on this, you should choose the model that best suits your pet.

Multifunctional collars

When choosing a flea collar for your pet you should check if it has an additional attachment that provides added value. These will depend on the manufacturer, but among the most common we can find collars with extra protection or that are water resistant among the most common.

Flea collarswith extra protection: this model of flea collars have additional chemicals to eliminate the risk of other insects such as ticks, worms or parasites. Usually the major flea collar brands already offer the extra protection in their flea collars.

Anti-water collars: this model of flea collars have a water resistance so that when our pet gets wet the collar does not lose its protection against insects. This model is essential for those owners who like to go outdoors with their pets.


Another factor to consider when buying a flea collar is how long it will last. Depending on the manufacturer, they can last from 3 months to 8 months. Therefore, it is important that we check if the brand we are buying offers us the protection time we want.

Avoid evaporation

Another vital factor to consider when buying a flea collar is to ensure that it does not evaporate after prolonged use in the sun. If a flea collar evaporates, it is detrimental to the pet's sense of smell and affects the protection factor. It also leaves an unpleasant smell in the home.
