My Jack Russell Story:
I own a Jack Russell Terrier/Shih Tzu mix (very strange looking I must say) named Knicknack. She does many strange things but the strangest one is when she is tired, her eyes don't synchronize very well. She'll be about to fall asleep when one of her eyes is looking at me but the other one is rolled back in her head. They sort of float around. I have never heard of this happening before. She really freaks out my company when they come over and see her eyes wandering around in their sockets.
