Cookiebaker,

My Rocky was the first puppy I ever owned that
ate poop, rocks and anything on the ground
he could stick in his mouth.

Rocky was fed a good diet so I new it had
nothing to do with lack of minerals etc.

With the rocks you have to be careful because
it can cause problems. I watched him like a hawk
in the back yard and repremanded
him when he started grabing the rocks,
but even than he snuck a
pebble hear and their.
I could not even take him for a walk with-out him
vacumming up the sidewalk.
Yep! you have to learn to be one step ahead
of your puppy, because they are fast.

Rocky did grow out of both Rock playing/eating
and vacuming up the sidewalks.
