Replying to a message of thinktank to All:

If you want.  I don't think it will hurt the dog if you don't.

It usedta was that there was only one kind of dog food.  Probably
40 years ago Purina brought out 'Puppy Chow,' which is optimized
for puppies as opposed to ordinary 'Dog Chow.'  Of course, today you
can get dog food optimized for puppies, optimized for adult dogs, and
optimized for older dogs.  Slightly different proportions of various vitamins
and minerals.

My dogs get 'Farm Dog,' which is made by Kent Feeds.  They seem to be doing
just fine on it.  I don't know if it's available outside the 'farm belt.'
