    They can be adjusted and fit most breeds, and since they’re environmentally friendly, you won’t feel guilty when you dispose of them.

    A downside of this product is that it does not disclose all the ingredients used until you buy it and can read the label inside, even though it advertises “all-natural” ingredients, so proceed with caution. The collar is also hard to adjust.

    Buyer’s Guide: Choosing the Best Flea Collars for Small Dogs

    Picking a flea collar is important for your small dog’s health, and one size does not fit all. Some factors need to be considered before purchasing, and in this buyer’s guide, we’ll go over them to help you even further.

    How Flea Collars Work

    Flea collars release chemicals on your dog’s skin and fur. They are designed to continuously release the chemicals, providing protection for 6 months and up. Flea collars can be a more affordable option than topical treatments, and you don’t have to worry about remembering to administer topical treatments monthly.

    However, some flea collars may cause adverse reactions in some dogs, such as skin irritation, vomiting, diarrhea, trembling, and even seizures. We recommend consulting your veterinarian before purchasing a flea collar to ensure its safety.

    Synthetic vs. All-Natural Ingredients

    Some flea collars advertise using only all-natural ingredients rather than synthetic ingredients. All-natural flea collars use essential oils, but some essential oils are safe for your small dog. For example, some all-natural flea collars use citronella oils, which can be toxic if ingested. When contemplating a collar that uses citronella, ensure the oil is on the inside so your dog cannot lick it off.

    Waterproof Flea Collars

    All the flea collars mentioned above are waterproof, which is an important feature to consider, especially if your dog loves the water. Bear in mind, however, that prolonged exposure to water may cause the collar to lose its effectiveness.

    Comfort

    The flea collar you choose must be comfortable for your dog. Most are easily adjustable, but the collar should not be too tight around your dog’s neck. Ensure you can slip two fingers between the collar and your dog’s neck.

    Another excellent feature to look for is if the collar has a breakpoint design, meaning it will release if your dog gets hung up on an object, which could cause choking.

    Efficacy

    Most of the flea collars we’ve listed protect not only against fleas but also flea eggs, larvae, ticks, lice, and mosquitos. Some also break the life cycle to prevent more fleas. It’s important to check the efficacy of a flea collar before purchasing it to ensure it will work for what you need it for.
