I am very much in the market for a new couch (the one we have now is a hand-me-down from my dad, and is starting to fall to pieces, besides being a kind of odd pattern), and asked Kristan to recommend fabrics for a household with a dog that loves to burrow. She said that microfiber is the best option for pet-friendly homes, because the fibers are treated, and spills bead up and come right off. 

Tip: To get scratches out of leather furniture, lightly spray a rag with furniture polish and rub it on the scratched area.
