Using your Weaver Terra dog collar is super easy. Just put it around your dog's neck and fasten it. When choosing a collar, make sure it's not too tight or too loose - you should be able to fit two fingers between the collar and your dog's neck. As for maintenance, keep it away from water as much as possible. If it gets dirty, use a damp cloth to gently wipe it clean. Let it air dry. Also, check the hardware regularly to make sure it's in good condition. Don't let your dog chew on the collar to avoid damage.
