Are you trying a clicker at all? And reward her for that half a sec that she does stay. Then when she stays for 2 secs...etc. Hard to get them to understand what they are doing right, if they are quick to move on. The clicker is quick & lets her know at that second, she was good. By the time you dig a treat out of your pocket, she can't understand what she did right...
I used em years ago, but really...a praise word works just as well, as long as it's a different tone than your regular speaking or training voice, & she knows when she hears it a treat is forthcoming.
Good luck! I am thinking about trying the show-rings myself down the road...lol. Going to a few coming up here in the near future first.
