Just to add to the crate training info...our first Boston Terrier, Pepper, we started with the crate at puppyhood, and she did wonderfully with it. As an adult, she'd go in it voluntarily when she needed "alone" time or when she was ill. And we'd put her in it if we happened to have a situation (like a toddler visiting) that we needed to restrain her. With few exceptions like those, after she was housetrained, she only went in the crate to sleep at night. DH did not want a dog or dogs in our bed, and I ended up being so glad he was a stickler about that as we only have a queen-sized bed, and this gives us a lot more room and peace (Boston Terriers snore!)

If you start your dog with the crate when s/he is a pup, they really come to enjoy being in their crate and see it as a place of refuge. Pepper was so good she'd stay in there, once housetrained, in the morning until we got up, even if it was 8 am or later (on weekends) without making a peep. Paisley stays in until 7 am now already (I haven't tried to push the envelope yet) so long as we let her out one last time at 11pm, and doesn't have accidents. She's not crazy about going in it during the day, but when we do have to put her in there for a short while when we can't watch her, she will settle down after some initial whining/yipping.
