The fun in raising a puppy...

[draggar]

Don't forget we have a very intelligent GSD and malinois (and the finkies were very bright, too). We don't deliberately teach them anything. Our GSD learned how to open the back sliding glass door (it does not have a handle on it).

She could also like metallic objects. A lot of working line GSD and malinois breeders will test their puppies' temperaments (and workability) by throwing keys into the puppy pen. Those that play with the keys would make better working candidates while those that didn't usually went to pet homes. Metal isn't something most dogs would want to play (chew) with and they make loud noises that they usually don't like.
