Here is a metal dog kennel that gives your pets plenty of room to enjoy exercise outside. The Pawhut 8′ x 4′ x 6′ Large Dog Kennel has a tough frame, so it protects your dogs from predators and bad weather. This kennel can be used for cats and chickens too.
You can expand this by connecting multiple kennels together. It has a UV-resistant Oxford cloth roof. You can find out more about it here.
