Have to totally agree with everyone else here.. My sister-in-law once tried this on the same basis, and the dog just totally howled the house down, messed, annoyed the neighbours and wrecked the home, month after month. The fact is that all normal dogs need CONSTANT companionship and affection, and greatly dislike being on their own. Therefore they will often become very psychologically disturbed if they're constantly left on their own every day, even if they get lots of attention in the evening (which doesn't always happen either). And 4 decent walks a day (NOT five minutes outside the door), EVERY day, in all weathers often proves to be too much for even the most dedicated dog-owners. All you'll be getting by owning a dog in your current situation is endless heartache - and the dog will get the same, so focus on a much smaller, quieter and less demanding pet.. Cat, rabbit, budgie.. even tropical fish... but a dog would definitely NOT work.
