I am trying to find out what happened to Lang's pet food from
Michigan..I used to buy it and it was great dog food...I am assuming
it went under and I might be interested in buying the defunct
company...it has disappeared off the map.

Debco --

I can find no reference to Lang's dog food except an article that
appears to have been written in the mid-1990s (from the bibliography):
http://www.macatawa.org/~wilcox_k/diet.html

A check of the U.S. Patent & Trademark index shows that the "Lang's"
trademark was not registered.

I went so far as to try the Infotrac business publication database,
which goes back to about 1980.

Is it possible that Lang's dog food is still in production - just
under a different name that you probably know; Dad's?.  It would be my
hypothesis (if this is the one you're looking for) that the original
Lang died and the family took over production and re-created their
"Dad's" recipe.

Not sure where Michigan would fit into this equation as Dad's is
produced in Meadville, Pennsylvania.
