Taco Bell Chihuahua Dies at 15

Karen McElhatton, Gidget's owner, tells Usmagazine.com the dog was with her trainer, Sue Chipperton, watching television when she began making "strange noises" and suffered a stroke.

Before the dog's death, "She had a good day and was running around as normal," McElhatton tells Usmagazine.com. "We're happy that she was very well off right until the end."
