There is a company in our area that has its business renting out their herd of goats. They use mesh electric fencing, partly to keep the goats in and also to keep dogs out. They use a toy hauler motor home to transport then to the site and then one person stays there for the duration of the job. Some jobs are for a day or two and some are for much longer. The owners bought 3 of our goats, including a cougar attack survivor. Goats do a great job in eating weeds and bush; goats are browsers while sheep are grazers. You can google goats on the hoof and get to their web site.
