We have a 8 month old puppy, Wilson. He has been with other puppies his whole life. We have had him a month now. He eats and drinks like he will never get anything else. We even bought him one of thos...
Our dogs were inhalers...but at some point (about 3 years old) they only ate what they needed. We were able to leave dry food out for them all day and they would nibble on it throughout the day. The two of them (medium size dogs) would eat about a cup each per day.
