Hi,everyone, I have work Monday-Friday, 8-5, My 6 month old boxer has to stay in the yard for 9 hrs by himself. What if someone walk in and take him out? I am sure you guys has heart lots of story about missing dog. Pleaes Kindly give me some idea, should I put him back in the house? I did that when he's 3-5 months old, but recentlly, he started get bigger and outgoing, I have to leave him in the yard.
