I'm going through a break up and will be moving out of current home. I have a large breed dog who is still young and excitable, needs about 10k of walking & playtime a day to really tire out. Currently live in a 4 bed detached house with good outside space. I love the dog so much and he is very attached to me rather than ex. However I am going to be moving back to parents for 6 months or so in a small 2 bed house while I save up / find a new place. My parents are not great with dogs so although they love him I think would struggle with him being there everyday if he is excitable at times. I also would be out of the house twice a week for work for a long period so would need day care. I don't really have anyone who could look after him when I need so would have to rely on day care/ dog walkers. I also think long term I'd be looking at a 2 bed flat to live in the city. I know I can work out logistics, but I'm worried that I wouldn't be able to give him the best life any more and could be selfish to keep him. My ex could potentially keep him in the current house and has a lot more help from family for walks etc but if not we would have to find him a new home. What would you do?
