Best Kind of Goat for Brush Control?

Question by Ashley: Best Kind of Goat for Brush Control?
We are considering getting a goat (or maybe more than one), mostly to help control the growth of our pasture. We have two horses on a 4 acre lot and they can’t seem to keep it eaten down. I was wondering what the best type of goat is to help with that. I am not really interested in using it for milk or butchering, more as just a pet and pasture mate to the horses.
I have electric horse fencing, however I have heard that goats are great escape artists. I was wondering if that type of fence would be sufficient to keep them contained.
Do you de-worm, trim their hooves and give them shots just like you would horses? Will they be healthy just from grazing or do they require grain?
Do they need to be kept with other goats or are they fine just to be in with horses?
I know I probably sound like an idiot, I really just don’t know anything about goats! I realize I’m going to have to do a lot more research before I commit to owning and caring for the animal, this is just my first step in the learning process. Hope you can help!
