I currently have a Rogers Goosebuster that I like. I have also owned Final Approach and Avery Finisher blinds, which were good also.
We hunt shoreline along a river that drops 11' from summer pool level. A layout for both humans and the dog is critical. The dog stays in a Mutt Hut type of dog enclosure and only breaks when it sees birds falling from the sky. The dog blind is usually placed up by the weed line maybe 60-80 yards behind us. The birds do not focus on the dog. After retrieves are made the dog kennels back into her blind.
We have snow covers for our layout blinds and dog blind. When the snow falls and you have a cover on you really disappear and the advantage is even more in our favor.
