Considering the age of the puppy, 10 weeks old, its doing what naturally comesto all dogs,

IMO this isn't a true statement at all, it is a cop out for the dog. The dog was born without a natural respect for mankind. Amimal agression and human agression in an animal aren't the same thing. If you breed human agressive animals to human agressive animals, it only get worse. This is done in show dogs to get the posturing needed to win the big money shows. Those that aren't show stock find thier way into "pet" homes with children for which the dog has no respect by nature. Its not in his DNA to respect humans. It has been bred out of him as with a wild animal. This pup IMO has just shown his inbred disregard for his master at a very young age and it will only strengthen itself with age. That is based on a lifetime of experience with big game hunting dogs, take it for what it is worth. What is the walfare of a child worth?
