Faith Martin’s Funny Dog ‘Crystal’ Howls at Facebook Dog! [VIDEO]

This morning I was looking at facebook and a dog howling to a kid playing harmonica. Then, my dog started howling! She hardly ever makes this kind of noise! I wonder what the other dog is saying...or if it's just a tone in the harmonica that makes a dog want to howl! At any rate...It's pretty cute! Check it out!
