Mentioned in the excellent I09 article about animals in costumes (very relevant to my interests) was Sgt. Stubby, the most decorated dog in WWI, and the only dog to be promoted to the rank of Sergeant through combat.
If the existence of Sgt. Stubby doesn't convert you to Team Dog, there's no hope for you. I mean, this is just SOME of his awesomeness:
-His name is SARGENT STUBBY
-"He saved his regiment from surprise mustard gas attacks, found and comforted the wounded, and even once caught a German spy by the seat of his pants, holding him there until American soldiers found him."
-"he could hear the whine of incoming artillery shells before humans could — became very adept at letting his unit know when to duck for cover."
-Did I mention his name? SERGEANT STUBBY??
Look at this face. LOOK AT IT.
I can't believe how much time I wasted in history class learning about things unrelated to Sgt. Stubby. It should be considered a war crime to deny schoolchildren knowledge of this little dog face.
SERGEANT STUBBY 4EVER.
