My daughter adopted a large 7 year old dog. She is now unable to spend time with him because of work. She wants us to take him on our farm. But can he adapt to being an outside dog after 7 years of being an inside dog? We have 2 other dogs.
I also think that he eventually will like the outdoors even more than indoors! There are so many things to smell and explore, so much space to run and play... considering that you talk about a large breed, I'm sure he'll like the new perspectives. What breed is he, by the way?
