Using your Li'l Pals Adjustable Dog Collar is easy. First, adjust the collar to fit your dog's neck comfortably. Make sure you can fit two fingers between the collar and your dog's neck. When you're out for a walk, you can attach a leash to the collar's D - ring. Remember to check the fit regularly as your puppy grows. To keep the collar in good shape, wash it with mild soap and water occasionally. Avoid exposing it to sharp objects that could damage the nylon material. If the snap - lock buckle gets dirty, clean it gently. This way, your dog's collar will last a long time and keep your furry friend looking great.
