I have a custom made "PIT BLIND" for a large sized Lab. This was custom made by a professional woodworker and never used. Box is framed out with a "Cresent Moon" top. The top is curved and the whole box is designed to go into the ground next to your pit. Hinged top allows you open/close it and room for your dog to see what's going on. $100.00 Willing to meet @ Cabelas in DE.
