Games and exercises which are engaging dog’s nose are a natural way how to provide the dog with both physical and mental stimulation and it has a positive impact on dogs temperament. It is also a good alternative way for the dog to release the energy in another way than just running or fooling around.
If you are interested in this topic I am recommending the book by A.L. Kvam –The Canine Kingdom of Scent: Fun Activities Using Your Dog’s Natural Instincts (Norwegian original is called “Nesearbeid for hund“) or a DVD by A.L. Kvam and Turid Rugaas – Nosework Search Games. You can also get inspired by my new video “Find the keys”.
