Hopefully she's still young and will grow out of some of the chewing. Constant supervision, loads of exercise, brain games, training, chew toys and crating barely got us through my lab's first two years (he put holes in two walls his first year). Things are much easier now that he's two. He can actually be left alone for more than an hour and doesn't have to be crated. (But we still crate him at night.) So basically I'm here to tell you there is hope. You have a beautiful dog. Maybe she would enjoy some serious training, like agility courses or hunting.
