I've gotten multiple accounts, and they all went right along with what gotap_d stated. Pretty was digging deep and hard on Queen until she came over the top and to the muzzle. Everyone was very complimentary of Pretty. One person even referred to her as a thoroughbred. She was every bit of that 39 pounds, and made Queen look little. No shade was brought up and no one had anything negative to say.
Hopefully Pretty can make a name for herself in the brood pen as well.
