Yesterday I had the absolute worst puppy class so far. My puppy was ignoring my treats outright and was distracted by everything (as per usual with her). My instructor gave me some of her treats which were exactly the same as I was using - Natural Balance - but they were in bigger chunks. That was the only difference. I've also noticed at home she will start becoming less and less enthused about high value treats, even ones that I don't use that much such as chicken for Crate Games and handling.
Has anyone ever had an experience with a dog that has "treat fatigue" and what did you do to combat it? Mix up the treats all in a bag and just randomize which treat they get? Or using one treat for a few days, then another treat for another few days and rotate? Or is this treat fatigue thing all in my head?
