If you have been to a puppy training class already, you'll know that trainers often require three levels of treats:
Low value - for basic good behaviors. Think low calorie, non-greasy. You'll give out a lot and don't want to overfeed (or grease up your pockets)
Mid value - a little bit more flavorful for a bit more memorable impression. Could be a really tasty kibble, or small biscuits broken in pieces
High value - the most tasty treats will leave a really strong imprint and your pup will want to repeat whatever she did to get another. Examples: freeze-dried chicken, liver or fish; meat jerkies.
