Answer:
I plow and plow, but never sow. What am I?
I jump when I walk and sit when I stand.
I roam through the lands hoping to rescue my love. I search high and low and will stomp on you if you get in my way!
The more of me you take, the more I appear behind you. What am I?
I dig out tiny caves and store gold and silver in them. I also build bridges of silver and make crowns of gold. Sooner or later everybody needs my help yet many people are afraid to let me help them.
Runs over fields and woods all day. Under the bed at night sits not alone, With long tongue hanging out, Resting at your feet until we go for a walk
