I read the booklet "before you get your puppy" and think I am going to try to use the Kong method to give my pup it's food when I get her. I was wondering if you just put dry food and treats in there if they get it out to easily, thus defeating the purpose of using it to keep them occupied during the day. I have read many other posts about people using pb and other yummy things but it sounds like they are using it as more of a treat than merely a way to administer food. Would it be ok to combine her normal food with something that's more of a treat?
