    Buyer’s Guide: Choosing The Best Flea Collar for Dogs

    Flea collars should be one of the first things you should use when you have an infestation of fleas. But there are so many brands and types in the market today that they can make your head spin. To help you with this, here are some factors to consider when buying the best flea collar for your dog.

    1. Smell

    Some flea collars may have an overpowering scent. You don’t want to choke your dog with a collar that smells like a rose garden. Make sure that the smell isn’t too strong. It should be subtle and natural, not synthetic, too flowery, or chemical-like. Choose something that you can tolerate, as the dog will also be comfortable with it.


    2. Size of the Dog Collar

    Flea collars come in different sizes. Some range from extra small, small, medium, large, and extra-large, depending on the size of your dog.

    You should measure the neck of the dog to buy a collar that will fit correctly. It should be fitted in a way that it sits snugly around your dog’s neck, not too tight or too loose, as this may cause discomfort to your dog. Thus, always consider the size as you shop around for a perfect fit.

    3. Water Resistance

    Water resistance is a primary factor when buying a flea collar for dogs. Fleas are also present in water, and if the collar is not resistant to water, it will not be effective. Flea collars need to stay on your dog even when they go swimming or get caught up in the rain.

    When buying water-resistant flea collars, make sure they have a waterproof seal. It ensures the collar will not break when submerged in water. The collar should also be made of materials resistant to salt and chlorine. This way, it can withstand exposure in swimming pools and lakes.


    4. Lasting Effect

    One of the primary factors to consider when looking for a flea collar for dogs is the duration in which it remains effective.

    Flea collars are designed to keep fleas and ticks away from your dog for long periods. Some of these products can last for up to eight months, while others are not reliable. You may need to check the instructions on the flea collar you are considering. This way, you’ll know how long this product is expected to deter insects.

    Timely removal and replacement of your dog’s flea collar are crucial to prevent any skin irritations or allergies.

    5. Ingredients

    Flea collars may have a variety of ingredients. Some are safe, while others can be harmful to your pet.

    The main ingredient in most collars is Deltamethrin. It’s a synthetic pyrethroid that is toxic to insects and mammals. In small doses, it will kill fleas. But in larger doses, it can be fatal to your dog. Read the label on the package before purchasing a new product.

    While most flea collars contain chemicals, some pet owners prefer natural ingredients. If you want to use natural ingredients, look for a collar that contains pyrethrin or permethrin. These are natural products extracted from plants and are known for their effectiveness against fleas and other insects. They will kill the adult fleas on contact. But these chemicals don’t last long on the dog’s hair. It means that if your dog has fleas, you must reapply the treatment every two weeks until all of them are gone.

    Some people prefer collars with no chemicals. Instead, they use only essential oils, such as eucalyptus oil or cedar oil. You can find these types of collars at most pet stores. But, they are less effective against fleas than chemically-based ones. It means that you will have to reapply often.

    Overall, depending on your preference, check the ingredients to ensure that you are purchasing a collar that will work well for your dog.


    6. Protection Against Other Bugs

    Fleas are the most common and the worst pests in dogs. A dog with fleas is uncomfortable and difficult to live with. By far, the best way to protect your dog from fleas is by using a high-quality flea collar.

    Most flea collars sold in the market today will indeed protect your dog against fleas, but they aren’t all created equal. Some offer protection against other pests as well, while others don’t do much else.

    The best flea collar for dogs should protect them against not just fleas but other insects as well, such as ticks and mosquitoes. These pests may also pose a threat to their health.

    7. The Dog’s Age

    Flea collars are safe and effective if used correctly on the right dog. So, consider the age of your dog before buying a flea collar. Some flea collars can be harmful to puppies under six months of age. Besides, the manufacturers recommend that you consult with your veterinarian before using any flea product on a puppy less than eight weeks old.

    If you have an adult dog, you may have more options when it comes to choosing a flea collar. But it is suggested that you avoid those that contain natural pyrethrins. It’s because they can cause severe problems to some dogs.
