My husband is in the middle of building our 20x20 outside run (we are waiting to the concrete to dry for the posts right now. We have chicken wire and plan to run it up 6 feet. We live in town and there are not a lot of predators, but I want to be safe. I'm actually more worried about any neighborhood dogs that get out. How do you reenforce the bottom? Do you think hardware cloth over the chicken wire would be enough? Or should I try to do some sort of wooden fence along the bottom? Thank you for your help!
