Keith didn't say he lacked the time: only the enlightenment: much like
most pet owners.

Quite true. And some 'pet owners who think they know things' can make for
bad advice.

At one time, I--and you--knew nothing about pet care. Far more than most
folks, I know your quoted statement is correct, but it doesn't need to
be said to someone who already has the puppy, and is trying to learn how
to become a good pet owner.

It takes time.
