What is Arlene weaning the puppies onto? Orijen has a good grain-free puppy kibble.
I feed mine twice a day. The best schedule I have found for housetraining is to get them up and out to potty first thing then they play while I get breakfast together, they get their breakfast and then are out again after 20 minutes, usually for a short walk. The pup is then crated or ex-penned while we are at work. One of us comes home for lunch and the pup is pottied and played with so they are ready for an afternoon nap. When I get home they go out again and then play with the "big dogs". Everyone gets dinner between about 5-6pm then they are out for their evening walk about 20-30 minutes later. Then I make sure the pups get a good play session before bed and out to potty right before. Usually it takes a few weeks before they can hold it all night so plan on pee break in the middle of the night, just pick them up and out to potty then back to bed so they know it is for business and not play.
