I have a big backyard (still in the states), but my dog just spends her days in the house. We had some chewing incidences just after she came to live with me--she was on the verge between puppyhood and adulthood, plus she was really stressed out--but I don't think I've seen her chew anything in years. She is incredibly lazy, and I suspect that she spends her days sleeping on the couch (an activity that is not allowed when I am home!). I read a million books on dogs before I got one, and I was pretty sold on the concept of crate training. However, she is pretty claustrophobic, so crate training didn't really work for us. She used to throw her body against the sides of the crate until I let her out, and this was with me sitting right outside the crate, trying to give her treats and telling her what a good puppy she was for being in the crate--I even tried getting into the crate with her, but she still hated it. I'm working on it again with the biggest crate available (she's about a 65 lb dog) in anticipation of our move, and that seems to be going better. She's much more grown-up and anxiety-free now, though, and I think that helps.
I think it is important to really read up on how to crate train well. I had friends who trained by leaving their dog in the crate only when they left the house. The dog was miserable in the crate, and I think it might have been because he associated it with his owners leaving the house. Everything I've read really emphasized the importance of training your dog to be in the crate while you are around, and offering lots of encouragement and attention to the dog as it gets used to the crate. Like I said, it didn't work in my case, but if you're going to do it make sure you read a book on dog training and do it right--most of the advice I read seemed pretty similar.
You may want to read more about types and breeds of dogs before acquiring a dog as well. Different breeds of dogs are going to be easier to leave at home alone, uncrated, while other breeds generally do not take well to being crated at all (Great Pyrenees come to mind, but I think most livestock guardian breeds are this way). It probably goes without saying, but if you aren't at home all day and don't have a yard, you probably want a pretty lazy dog. While many dogs are mixes, you can infer a lot about a dog if you have some sense of its heritage; none of these are absolutes, of course, but it should give you some guidance. I've seen a lot of people/dog relationships not work out because people didn't seem to understand the basic tendencies of a breed. My dog is a Pyr/poodle mix (I think) and I've found that reading websites dedicated to Pyr behavior and training have been really useful.
