When my girls were young we were going to visit a friend of ours who lived on a farm (we lived in Missouri at the time on 1 acre w/a small fenced back yard) and they took my friend some glads from my garden, in return she gave them a baby goat. Rosie slept in the dog house with Scruffy our dog until we were able to build a proper pen for her against the tiny barn on our property.
She would get ticked off because we would let the dog in the house, but not her. After about two weeks of looking in the dining room window at us and voicing her protest, she climbed over the fence and went to the front door and knocked.... okay head butted... the only way we could get her back into the back yard was let her walk through the house.... she looked in all the rooms, then docily went back to the yard.
She would do this about every 4 or 5 days... until we built a fence she couldn't scale. The neighbors (and the kids school bus driver) got a kick out of seeing her sitting on the front porch waiting to get in. Unfortuantly she taught the dog to climb the fence and unlike the goat the dog would run away!!! got a few citations from local animal control... but wouldn't have traded that goat for anything. She played tag with the kids, played w/ the dog and every morning at sunrise had a chat over the fence with my neighbor and her 80 year old mother. I can't wait til we have our place and can get a goat or two.. not for milk (that's more work than I wanna do)... just for the joy of having them around!
