Al and Becky explain Canine Nose Work in My Pet.
Using his sharp sense of smell, your dog searches for the food treats hidden in the box. The game keeps getting harder with multiple boxes.
This fun game challenges your dog physically and mentally. It is a great way to bond with your dog. It’s also the basis for all nose work including Search and Rescue, Drug Detection and even Diabetes work.
