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. Certain factors need to be considered before purchasing, and in this buyer’s guide, we’ll go over those factors to help you even further.
How Flea Collars Work
Flea collars work by releasing chemicals throughout the oils in your dog’s skin and fur. Flea collars are designed to continuously release these chemicals that will offer 6 months and up of protection. Flea collars can be a more affordable option rather than topical treatments, and you don’t have to worry about remembering to administer topical treatments monthly.
With these collars, you can apply them to your dog and forget about it for several months. Bear in mind, though, that some flea collars may cause an adverse reaction 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 not all 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 of the collar 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 be too tight around your dog’s neck. A rule of thumb is to 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 that 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.
Conclusion
We hope our reviews of the top 10 flea collars help you in making an informed and safe decision for your small dog. To recap, the Adams Flea and Tick collar provides 7 months of protection, kills fleas and ticks instantly, kills flea eggs, tick larvae, and tick nymphs, and is designed for small dogs for the best overall flea collar. For the best value, Hartz UltraGuard Pro Reflecting Flea & Tick Collar provides 7 months of protection, features a reflective shield, breaks the reproductive cycle, and is water resistant.
When in doubt, always consult your vet to provide the safest option for your small dog.
