Drake doesn't bark much unless he we're wrestling around or playing and he wants his ball or he hears raccoons outside. When he want's his ball it's sort of an impatient "Woof!" but when he hears something outside, he does what we call the "Scream Bark". It's always at night when we all are falling asleep in front of the TV. He will appear to be sleeping and then all of the sudden he lets out a loud single bark that wakes us up with a heart attack. Then, if he happens to be sleeping on the hardwood floor, he tries to get up as fast as he can and ends up digging big grooves into the floor. Every scratch noise is like fingernails on the chalkboard, we try to get him to sleep on his dog bed now but he prefers the cool floor. So once he gets up, he growls until he gets to the sliding door and then it's, "Woo-woo-WOOOOOOOO!" You can actually feel his barks! So to placate him, we let him out and he can't get through the door fast enough. You can hear him flying down the deck, paint getting ripped up with every step, and more scream barks. On the flip side, we have taught him to "whisper" for treats, it's pretty funny and very cute.
