DH got creative with the lumber we had...this is 8ft X 8ft with removable wheels for portablity, and removable handles. We used a hunting dog travel box for their housing right now he has to go get more wood and then he is going to mount it on the back of the pen and he is currently builing a divider pc. so we can have 2 pens in 1 for different ages and it will be removable also....He is so CRAFTY!!!
