Answer:
I produce wool and spit a lot
I come in different colors and shapes. Some parts of me are curvy, some are straight. I look like I can belong anywhere but there is only one right place for me. What am I?
Many people own a copy of me. Without me the world would fall.
I have two bodies joined together as one. When standing still, I run and run. What am I?
There is one in every corner and two in every room.
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
