You really do not need one. I do alot of dry field hunting just train your dog to lay down next to your layout blind.This year I will hunt SD, IA, NE, OK, MO, TX, KS all dry field hunting. I will not have a dog blind with me. A dog blind is one more thing that needs to be brushed up. A dog that is well trained is more important than a dog blind.
If it bleeds I can KILL IT
