I have had dogs all my life and i want a dog now, but i want a good, trained dog.
Unfortunately, having a good well trained dog is a function of whether or not you are committed to making him good and well trained.
Dogs don't just automatically know what is right and wrong. They have to be taught. I can sympathize with your plight of not having enough hours in a day, but it doesn't take that much time out of your day to train your dog.
Start with EXERCISE, as everyone else has said. When my dog was one, if she didn't get an hours worth of exercise, she was an absolute nightmare. Do you run/walk? Take the dog. If not, hire a neighborhood teen to walk him daily. I'll bet you can find a pre-teen who will do it for 5 bucks a day. Wouldn't it be worth $20/week to you to have a dog that is calmer? Do you have a backyard? Sit outside while you're on the phone, reading the paper, whatever, and throw a ball for 30 minutes. Is there a dog park nearby? Take the dog when you can manage. Do you have a doggy daycare? Drop him off to play. You'll notice a huge difference in your dog's behavior when he's stimulated and exercised on a daily basis.
Secondly, NILF. It takes absolutely no time, just commitment to make the dog work for what he gets. Instead of just filling up a bowl of food and giving it to him, tell him to sit. How much more time does that take? Instead of petting him when he's going nuts, make him sit. It's not that difficult and takes no time at all.
And finally, while you're watching TV, why not grab a bag of treats and give him commands, rewarding each time he complies during the commercials of your favorite show? That is training. If you can do 10 minutes a day, your dog will start learning what is appropriate. In the time it took for you to write this post, you could have completed your training for the day. It takes no time and you'll get the dog you always wanted.
Entertain other options. There are a million of them.
