I have goats, most of which I have in our pasture. However we do have a family milking goat that we keep in an x-large dog kennel with shelter, water and fresh hay. During the nice days she is "staked" out and can reach shade under one of the trees and a water bucket (which we have to refill 2 to 3x as she loves to push it over). I dont stake her during the rain, in the snow or severe heat or when I am going to be gone more than an hour. That being said, I personally wouldnt stake a goat that was not full sized (like mine) and with a full set of horns to protect herself and release excess heat. Large fully horned goats are not easy prey, even staked but as I said, I wont leave her long. IMHO, leaving any kind of animal on a permanent tether is dangerous to the health of the animal. Goats are intelligent, social trouble-makers by nature and I believe in fencing animals in, not tying them up. Again, this is just my opinion.
