In a stressful situation, most animals click into "fight or flight" mode, meaning they either run away from the danger, or stay and fight. This little dog can't seem to commit to either.
As a result, the pup appears to be stuck somewhere in between the two responses, which means: Doing nothing. Absolutely nothing. Not even moving.
Every time he's picked up, he freezes and stays fixed in whatever position he assumed prior to being picked up. Either that, or he knows the "stay" command a little too well.
