A puppy is not a toy. It needs to be fed often when young.
Young pups are especially vulnerable to broken bones and other injuries from careless treatment.
A puppy is not a teaching aid. A puppy should never be obtained to try to instill a sense of responsibility in children. It's unfair to place a defenseless animal's well-being in the hands of children. Feeding, grooming, housebreaking, and discipline training of a pup should be the responsibility of adults. A puppy is not cheap.
