I have a 110 pound American Bulldog that is four years old, she was born deaf. We made it through the puppy years and she has calmed down quite a bit. I always knew she was a little nutty and I was ok with that. Well imagine my surprise when I walked into my livingroom today and saw this...... Looking like Snoopy! Then she proceeds to bark at me like I was crazy! Yup, that's a glass table! She is a challenge!
