I think a muzzle would hurt Norm's feelings. In his defense, he isn't too much of a barker. Just when someone parks on the street close to our driveway, or to our closest neighbor's driveway. It's hilarious because we will say"shh!" and he'll do it again, but with a lower tone and quieter, then we'll shh him again and he'll do this "burrf" noise that's almost a whisper. A Great Pyr visited our office the other day, and I discovered that they have double dew claws. I had not known that before. She was so nice, and sat right away when I went to pet her. And BOY, I can see why them call them "Great!" She was a big, big girl. Those paws were bigger than my fist!
