Hi Souraya
When we go into the mountains to the cabin we always bring a flexible metal type fence we got from Petsmart. Our daughter-in-law also has one and we hook them together in the living room of the cabin so the dogs (4 of them) won't get out when someone opens the door. They come in many sizes and as tall as you need. Maybe if you got one or two of them and hooked them up in the largest area you have and put toys in with him? They just hook together and when you are not using them they fold up. Just a thought. Good luck, maybe a kong.
