So I was thinking about getting a goat for one purpose, keeping about an acre of black berries down. We are not fenced but also have no predator problems since we are on acreage in the middle of a city (land from 60 years or so ago that didn't develop like the rest of the place. I was thinking to make a small dog house for it and tether it where I want it to graze during the day. Else i can rent goats for 25 a week each. What are some pros and cons of this crazy spur of the moement idea after tiring arms of manually cutting the black berries?
