Congrats on your puppy!! We have a five yr old cavalier king charles spaniel. They are complete cuddlers, and very low energy requirements. And as a bonus, they are not chewers of everything in site.
We keep Oliver in a sectioned off part of the basement with a bed and blanket and food/water. Oliver sleeps in our bed and has never been crate trained so it would break my heart to put him in a crate. He is too much of a people person/socialite to be confined. (I know, dogs love crates but he wasn't trained as a pup so we love our little arrangement).
Just make sure to get him a nice soft bed he will love it i promise.
Oliver took 6 weeks obedience classes too, but can't say he retained much.
good luck and enjoy!! What colors is he? I really really want a ruby now.
