What to Look For in Flea Collars for Dogs?

There are several key things that you need to keep your eye on when choosing a collar. A design that has the perfect balance between these aspects is the one to go for!

Active ingredients

Paying attention to the ingredients contained in a flea collar can be the most important part. It is crucial that the ingredients are either veterinary-approved or totally natural. Otherwise, you risk irritation, allergies, lack of effects, and smelly, oily collars. Some brands offer natural ingredients such as essential oils, while others rely on powerful medications that are proven to work against fleas.


Finding the right size for your dog is also crucial. Just like any other collar, this one too can be too tight and cause chafing and irritation. If it doesn’t fit, it can also snap quite easily. Look out for easily adjustable collars with a “one size fits all” design. That way you can make the ideal fit for your dog.


Flea collars for dogs are meant to have a lasting effect that remains active for a certain period of time. This is great for the hottest season of the year when this issue is most prevalent. Choose a collar that helps you cover most of the year. Some offer as little as 4 months of active effects, while some offer double that. This means that with just two collars, you can keep your dog protected throughout the whole year.
