I think a big part of these interminable arguments about tabs is based on people using the same words to mean different things. In the following, I'm trying to avoid espousing my personal religion here, I just thought it would be good to try and explain the various sects. Anyway.
Puppies may be placed in new homes once they are eating well on their own. However, they will be better adjusted and make better pets by staying and interacting with littermates and the Mom-dog until they are at least eight weeks old--older generally is better.
Once you bring your new puppy home do NOT use puppy pee pads. Never, never use a pee-pee pad or have a potty station inside your home after the puppy is 8 to 9 weeks of age. You want to expand on what the breeder has already taught the puppy and take it to the next level.
