One of my fiance and my dogs has a very high pitched bark. She's a border terrier, and there are times when it really gets to me. But for the most part, she's worth dealing with it. Besides, I just listen for the tiger growl of my pitbull when she starts barking at the door. He's always close behind. One of our other dogs, though, has a mid range bark but it's like the volume is turned up on high. That's the one that bugs me the most usually.
