i rekon she will make around 25"
which is spot on for bunnies, she will probaly make a good alrounder too .
my dad used to have a 26" lurcher that used to take the piss out of rabbits .
youve got a nice dog there mate,
try not to start her to soon on the bunnies tho,
let her grow ,and give her easy ones at first to build her confidence.
all the best with your dog.
keep us posted
