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.
The Facts. Puppies are generally ready to eat solid food between the ages of 6 to 8 weeks old. However, according to Purina, it's not uncommon for puppies to start eating from their mother's dish at 4 or 5 weeks old. A puppy attempting to eat adult food does not necessarily mean it's ready to be weaned.
