Animals are only dumb if you don't spend the time to let them get to know you and the routine. Any animal can be trained if people treat them with the respect they deserve.
Some of the awful things I have heard people say about goats and people's perception about goats being evil in general! They are nothing like that and if they do do something they shouldn't I can usually trace it back to something that is my fault - e.g. not latching the gate properly - instead of blaming the animal.
Your sheep milk soap sounds lovely Bel. I make goat milk soap that we use at home. I would like to register later this year and start trying to sell some but see how we go with the costs etc first.
