Free boxer/pit mix for rehoming

This is Lucki, he is a 2 year old boxer/pit mix. We would love to keep him with us but unfortunately our living situation (downtown apartment) and long work ours, I fear are causing him become unhappy. He would love somewhere with lots of space to run around and play. Maybe even have a sibling as he is friendly with other dogs just shy and anxious at first. Hasn’t been around young children for long periods so not sure how he would react with them. Overall a very curious, protective and loving dog, always wants to follow you around or just be near you. Unfortunately we have had trouble getting him off of pee pads since he is left alone for long periods while we are at work. He is a smart dog, I know he will learn quickly with someone who has the ability to spend the time he needs. His favourite things include: cheese, burying his toys then searching for them, soaking in sunlight. We love him deeply but understand that at this time we aren’t able to offer him the love and attention he needs/ deserves. Just want to make sure he will go to someone who does.
