1. Can the dogs abilies be used on a pastures? Can i place a dog on a pasture and let him watch over extra sheep?
Yes and no. You can use dogs in a pasture, but if you do then you do not also get credit for the base number of sheep which can be kept in the pasture. So it is not "extra" sheep, it is "all the sheep there".
2. On round four...if I have 2 dwarfs and 1 babydwarf....do i pay three food or just 2 food for the dwarfs...and 0 food for the baby..
3. Baby still needs the 1 food.
