yes you do not have to dry her off to breed her UNLESS you have to take her to a buck and leave here there. But as long as she is able to be milked each day you can get a buck and breed her and not dry her off.
The dry off process is to be done slowly and I suggest you sort of set a goal to have her dried off -- like a 3 week mark after starting.
First you want to get her down to once a day milking. Then dont milk her all the way out each time you milk. Soon you can milk once every other day, then every three days. Once you believe she isnt making milk anymore leave her for a day or two and then milk her all the way out so that the milk doesnt say in her bag and cause issues. LIke I said this usually takes like 2-3 weeks depending on how much milk she is producing.
