Our yard here isn't fenced it. We have conservation land abutting us, so we can't put a fence up across the back. Instead, I have a trolley run for Wolfie that goes the entire width of the yard, and he can go 10 feet out front and back from the run. I out him out for an hour at a time a couple times a day. He runs back and forth, digs, climbs things, etc. Generally has a good time out there. I guess he needed something new to do because today, he made himself our log stacker. He has been taking the cut wood out of the wood pile and making a separate pile int he middle of the yard! My son is not going to think its so funny when I send him out to restack the logs. LOL!
