Teaching your dog to track by scent and find something can be crucial in training a service dog or a working dog. However, if you're teaching your dog to track by scent and don't plan on having a working dog who specializes in search and rescue, he can still be quite useful around the house. Dogs have a sense of smell that is hundreds of times stronger than humans have. Teaching dogs to train by scent can be the beginning process of teaching your dog to hunt or help you search for lucrative items to sell such as truffles, mushrooms, or even potentially find gold and silver. Teaching your dog to find items by scent could help you find a missing pet. You can also turn scent searching into fun and games by just hiding things in your backyard and rewarding your dog when he finds them. Search and rescue dogs use their sense of smell to find missing people or people lost in tragedies and horrific events or natural disasters. Utilizing a dog’s sense of smell makes the job of search and rescue faster, saving lives.
You're going to need some reward treats as well as some treats or foods your dog can sniff to find. Be sure to make these separate, so your dog is not searching for his own reward while doing his task. You may also want to use some toys to entice and encourage your dog, a large grassy area, and some patience.
