You can wash a puppy at any age depending on how you do it. Newborn puppies can be washed gently with a warm washcloth, and you can use most dog shampoos once puppies are at least 12 weeks old.
yes dog mature at a different rate than humans
A puppy can be 1 year and 6 months old to have puppies (female), and to leave another dog pregnant 9 months (male). You might wait longer, if you are not interested in breeding them as young as possible. A female can have puppies until she is 8 years old and a male until he dies.
Yes the puppy should be fed 4 to 5 times a day.
A.S.A.P!! your breeder should have done it when the dog was pregnant and first couple of weeks old.
