If you're questioning treats for training, I've just started researching the topic for myself. Carter and I had our first obedience training session this morning and his trainer used cut up (very small pieces) of hotdog that Carter absolutely LOVED. He has never had people food of any kind.
When we left the trainer's house, I stopped at PetSmart to see what was readily available. What I decided on for the short term (until I can research more thoroughly) is Nature's Recipe Training Treats. They are very small, soft and pork chop shaped. I easily split them in two or three pieces to make them even smaller.
http://www.naturesrecipe.com I don't see it on their website however.
I'll let you know if I find something else that is better.
