Flooring: Can all my doggies friends comment on the best flooring for a room that is a doggie highway in our house? We are trying to compare hardwood, engineered hardwood, or laminate. I always thought I didn't want laminate, but the store guy, who seemed to know what he was talking about, sounding very knowledgeable about flooring and owning two very active large dogs, recommended laminate. Any recommendations from my dog owning friends with hardwood type flooring?
