tough call mate, always liked the look of her,i had a similar situation in nov,had a big 26inch bull x that was doing everything i wanted, and doing it very well.wouldnt have parted with him for love no money, then out of the blue he jumped a gutter and fence and pulled the throat out of a sheep on my permission 100yds behind my house, sadly he was dead within 1hr, im surrounded with sheep in cumbria so he had to go, all the best to you and the dog whatever you decide
