as said before fella.... take her out and about with you, show him farm stock be it sheep, cows, whatever... you carnt over expose her!!! keep doing it till shes just not bothered.... then you can think about removing her lead mate...
take her out as much as you can, give her as many opportunties to learn, see how she develops... see how much you learn, you'll come to appreciate her in a different light..
i have a border bitch here same age as yours but have done all the above since she had her jabs!!!
from about 8 months she found out what her nose was for, be it rats,rabbits, sqirr
