In my old neighborhood, there was a house on our walk route that had a fallen tree in the yard that the homeowners were too lazy to cut up and move. They had one dog tied to each end of the tree, another dog tied to a tree that was still standing, another dog tied to the house, and another dog tied up to a stake in the back yard. I never saw them interact with any of the dogs in any way.
Mine stay out in the yard, too, but they come in when I leave the house, simply because they're both flight risks.
Well, that's not really true. They're usually inside with me, but they do sometimes stay out the majority of the day if it's nice outside and I don't feel like dealing with them, lol.
The last sentence of my previous post wasn't directed at you, smitty. I was just venting.
