Our Boston just loves his crate. We brought him home in it, and had him in it every night, and anytime during the day that we couldn't follow him around. They will chew anything, just like babies, and you have to watch them just like toddlers.
Crates are not confining to puppies. Puppies' mothers keep them in a small space just like that. They only let them out to tumble about when they are watching them. Your puppy will feel more secure in a crate.
As for potty training, I have only two things to say. One, be sure you take the puppy to the BACK of your property. If you teach puppy to go as soon as he gets outside, he will continue to go there, and you will not like walking out your door! Two, it may not take some dogs long to learn, but let me tell you............my dog is 7 years old, and is FINALLY accident free. His main problem is that he's scared of EVERYTHING, and doesn't like to go outside much at all. But, he doesn't like being in trouble either, and finally got the picture.
Lastly, be careful having your dog be an outside only dog. Many times outside only dogs don't learn the manners they need to be invited in, and unless you're really backyard people, they end up left alone. They are pack animals, and desperately need to be with their pack, which is you. Besides it being just plain sad, out of desperation, they get a lot of behavior problems being outside..................barking, digging, climbing, jumping up when you go out, trying to squeeze in the door.............and then they aren't potty trained, don't know to stay off the couch, etc., so they get kicked right back out again pretty soon. I've had outside only dogs, and indoor dogs.........the happiest dogs and the ones I've been happiest with, were the indoor dogs.
Just edited to say, like Mabel's parents, we also ended up getting up in the night to let our little Boston pup go potty. They are just like toddlers!
