Elfomatic, I know they use that particular test on older dogs to test for food aggression. I should have worded my post differently to say that I have never heard it being used to test food aggression on a 7 week old pup. It just didn't make sense to me.
Dawsons Dad, I think you've hit the proverbial nail on the head. The language hurdle does make what Dirk is saying sound less than serious, and almost joking.
I am so sorry if my post offended anyone. It's never my intention to insult, make fun of or hurt anyone's feelings for any reason. If I have, I truely apologize.
The entire subject is puzzling to me.
If I try to think about it rationally using what I know about dog behavior it makes sense to me that a dog who hasn't had any socialization, but has spent his life in a shelter cage with little or no interaction with people or other animals would view a rubber arm on a stick coming at it a threat and would naturally lash out to protect itself, especially if the puppy was very hungry and not secure or sure that he'll always be fed.
It's also possible, based on the temperament and age of the pup, that the dog would view the rubber arm as something to be curious about and investigate it with his mouth. That is what young puppies do.
I believe without the full story and all the facts, this may remain a mystery, as it just doesn't add up to me.
Dirk, where did you get the picture of that puppy? I could swear I have seen that picture before somewhere else. Just curious
