There are many reasons why pet owners outfit their dogs with dog collars. The most common reason is to control the dog's behavior with a leash attached to the collar. Leashes usually have a clip that hooks on to a metal loop that secures it to the collar. Dog collars are also used to secure identification (ID) tags that have the animal and owner's names, address and telephone number printed or engraved on them. Another popular reason why pet parents place a collar on their pooch is to distinguish the animal's gender. Female dogs are often observed wearing pink, purple and red collars adorned with shiny jewelry. Male dogs, on the other hand, don blue nylon, black leather dog collars and spiked dog collars. Collars also symbolize proud ownership. Your dog's personality may help inspire your collar choice. Perhaps something playful for puppies, sparkling for poodles or rough & tough for rottweilers, your options are limitless. Most of the collars we carry are adjustable and available in a variety of sizes and colors. If you have questions about dog collars and leashes, feel free to contact us.
