I have never ditched the bowl (the more popular term for Yin's approach), and I never will. I don't find it necessary, and I don't like the idea of my dogs having to work for every single morsel - they wouldn't as "wild" (village) dogs. A lot of scavenging yes, but many are also actively fed by the villagers, and they evolved alongside us eating what we threw out, so working for food is minimal compared to their wolf ancestors.
So, mine have mealtimes, and they have enrichment and training on top (and mealtimes are enrichment in themselves, too). I make allowances for what I'm using in training by just keeping an eye on their weight, so my 6 month old is from today having his meals cut down a little as he's getting a bit heavy, between lots of food hunting in the garden, chews to curb his teething, and not a lot of exercise over the past few weeks for a few reasons. But that's as far as I go with it really - I just check his ribs daily and adjust his meals by eye as needed. I never weigh anything or dish out his meals ahead of time and take food from those for training. It's worked fine for me for 18 years, 18 dogs and 4 puppies in that number!
In terms of the training itself, at the beginning I concentrate on day to day stuff: housetraining, name recognition, and starting recall. I started lead training him at 11 weeks, and by then his recall was coming along nicely too. Everything else has been left until now and he's just been allowed to be a puppy, have fun, charge about with my others and build fitness and condition. I've also built a good history of swapping items for food, so that if he steals something (and he is quite the thief), he brings it to me readily if I call him instead of running off with it and staying out of reach.
Now, I'm beginning to build things up, as he is going to be an agility dog so I need to get some tighter obedience in place now. Today I'm working on his wait, and starting some fundamentals for control around agility jumps (no actual jumping, just maneuvres). Nothing too strenuous, just getting the ideas in place so that when the class restarts hopefully at the end of next month, he'll be where he needs to be.
