If the cows you moved were gentle and she would not lot up with them then I would go with some good well trained dogs
if she is drinking from a trouth move it to the lot let her use it for a few days then shut her out for about 3 days then open it back up and it does not usely take long for them to go get water when reopened.then you got her if you can get the gate shut.if she is a hard to handle at a young age she needs to go to town or she will just be a problem later on down the road
