I just brought home an 11 month old male German Shepherd last night. A friend called and asked if we were still looking for one. I told her that I had just gotten one and she said that this one was going to go to the pound that day if no one would take him. I was told the owner is sick and can no longer care for him. So I did not want to let him be dumped off at the pound so I said I would take him. My sister in law may take him. I have 2.5 Acres but it is not fenced, so he is in a dog run that is 15'x8'. He wants out and he looks bored. What can I give him to do? I do let him out to run and my sis in law is going to see how he is with horses and start taking him on rides with her. But I just need something for him to do while he is in the cage. I dont want him to develop any bad habits.
