Chihuahua breeder Frieda Kane found her 5-year-old female, CH Guichon's Tika Toy ("Tika"), shaking out of control. Kane felt her heart beating fast as she ran to the dog. "I had just let the dogs inside, and she was missing. When I found her, I thought she was choking, so I picked her up. Then, all of a sudden, she went limp in my arms. I thought she had died," recalls Kane of Durham, N.C.
