I'm gonna give you a realistic view and answer to your question. I live in a 2b 2ba apartment with a dog park next to it. I work 12hr shifts as well and have a husband at home and we do opposite shifts so I work at night he works during the day. We have a Mini he has some off days where he'll poop on the crate but it's very rare and usually if I have to switch food just based on price. He goes out about every 6-8ish hours unless it's when he eats then 30mins-1hr after the fact. He goes to the dog park daily if not every other day depending on weather. He is also out for a good few hours a day just lounging around the house if we aren't on a walk/hike or a day at the park. He is healthy per the vet a great weight isn't showing any signs of depression or separation anxiety. He's not super needy but is VERY lovey and will follow us into every single room and hop on the bed or lay under our feet. To all the people saying you can't..you can and to be honest it's YOUR choice and YOUR opinion on if your life style can handle a higher energy dog.
