The puppy doesn't seem to be motivated by food or treats. If you use her prey drive to train her, I don't think treats come into the picture. At least in my experience.
I do not use treats for training or motivation and I say feed the dog if she's hungry before class. Maybe it will keep her mind off of eating if her motivation is prey.
'Course I've only been doing this for 25 years so what do I know?
