Mine get a ton of different treats during training. The only ones they don't have to work for are Old Mother Hubbard peanut butter biscuits - they get those when I leave for work in the morning.
Current training treats: Fromm's Surf and Turf and Salmon ala Veg dog foods, Premier's Liver Biscotti, Wellness Wellbites in salmon, Cloudstar Soft and Chewy Buddy Biscuits in Beef, and Ziwi Peak cat treats in venison or lamb.
I occasionally will make tuna brownies, but that's infrequent, so most of my treats are storebought.
Edible chewies include Wholesome Hide rawhide, Zukes Z-Ridge Bones, Merrick tendon chews, and I just bought some hardened sweet potato rings for chewies that will be saved for the dogs' christmas stockings. [:) ]
