A successful handler has the knowledge to confidently support his or her dog in searches. Awareness of scent theory is key. Whether new to the sport or more experienced in training and competition, understanding how odor travels in varying environments will increase your ability to understand your dog’s behavior. In this webinar, Donna will help participants to improve their skills by offering a deeper understanding of how odor behaves in certain locations, as well as in various conditions such as heat, cold, humidity, and rain. The importance of air movement will also be addressed. As more nose work trials open up in 2021, this webinar offers an excellent opportunity to increase your knowledge of scent theory and support your dog to success in searching for odor.
