Soo... I would really like to start leaving treats throughout the house and next to the back door, but I mainly get things that need to be refrigerated. I can get treats that don't no problem, but I feel like leaving them in cups or bowls will make them stale. What do those of you who leave treats throughout the house use? Also... I just registered for my first Nosework class with Rider. It starts Feb 7th. I'm super excited and super nervous. I've been really trying to work on focus in weird/stimulating places. Wish me luck!
