Like I stated earlier I have crated Baxter for 9 hours at a time. He is crated usually 1 day a week but no more than 3 days a week. Days he is crated when I return home we take a 2hr walk/run. He is not crated in the evening either(he sleeps in my bed). Since I got Baxter when he was 9-10 weeks old he has never chewed one item in my house but he did have frequent urinating accidents. I would crate him because he never urinated in his crate but would not have a problem "doing it" on my carpet. Now that Baxter is over one year old he no longer has these accidents. I have been leaving him out of his crate for periods of 5-6hours at a time and he has been wonderful(accident free). I still don't think I would leave him out of the crate for 9 hours. So in short I believe if you have to crate or tie your dog everyday all day due to work etc... you shouldn't have bought the dog but if it is infrequent crating I don't have a problem with it.
