I saw on the show Generation Kill that when humans get a big amount of adrenaline they start shivering.

Is this true for other animals? Because my dog goes crazy whenever someone pushes the doorbell, and he barks at all strangers. The guys fixing our sink came over and he barked like crazy and I brought him to my room. His heart is beating like crazy but now he's also shivering a lot.

Is this because of the adrenaline?

It's your dog's little way of telling you to train it not to bark uncontrollably at your house guests.

Seriously, look it up.
