UKC had too many Button's on their registry when we went to register her papers with them. Since her docked tail as a puppy reminded me of a machine button or on/off toggle switch, I knew I was gonna call her Button no matter what. So we sent the forms back in with ButtonButt as her name on her papers. THAT one they would accept. LOL Man, sometimes I wish that on/off toggle switch of hers really worked!!! Rat Terriers can really be relentlessly persistent and too energetic when they want something. LOL
