Major upset at the cowboy house today. Two or my loving little Chihuahua's decided to see if they could kill each other. They are best of friends sleep together most of the time. Will even eat dry food out of the same bowl at the same time. Today they decided to see which one had the stronger jaw grip on each others neck. My wife having a heart attack over it them yelping in pain and me trying to pry jaws apart. I just don't understand what got into them. even spraying them with water didn't work. Scared the heck out of me.
