what would your trainer have done??

[codmaster]

If you think that your trainer is afraid of a 14 week old puppy, I would run not walk to a new trainer! That sounds ridiculous (if in fact she really is afraid).

And i defintely would never treat a dog for food/resource guarding or even if it (more likely) just a puppy playful behavior or one trying to be a big dog. Could also have been influenced because the puppy was in with strange other puppies.

BTW, I would have just reached over to the puppy and taken the toy while talking to the puppy - maybe a treat AFTER I had the toy. But then I am a fanatic about my dogs NEVER showing any aggression whatsoever when I or family or friends take something (anything!) from them. Not acceptable at all! Way too dangerous with such a big dog like a GSD to have any of them get too possesive.
