Which breed has the most dog show wins?

Back in 1988 - 1997, Acey, a German Shepard (female) won over 320 dog shows in her lifetime. Living to be over 15, Aceyn stopped agility and frisbee trials at age 11. She had a disease called gigeliteus. Which is where a dog cannot move around very well. She still did obedience trials, but only for one more year and losing abour 2/3 of what she did. My great grandma was the owner of Acey and that is how i know this story :)
