Never mind the mess, I was in the process of adding outlets and insulating at the time. I've added a heater, insulated, and sheetrocked since the picture. I am currently in the process of taping. But this should give you an idea of what I did for my springer. I had a custom stainless top bent and welded for this as well that will give a nice surface to clean fish on or whatever. I also stained it with outdoor deck stain, which I would highly recommend. Whether its snow, rain, or aggressive drinking.... it gets wet in there from time to time.
Not that I minded having him in the house....But he is a pretty energetic fella and is much happier outside where he runs and runs and runs. Outside of the dog door, I poured a 6 x 16 concrete pad and put a powder coated kennel to keep him more contained when I don't want him to have the run of the yard.
It is a little more work to ensure that he gets all of the attention he deserves, with him being an outside dog. But it encourages me to get out and be active with him anyways.
Sorry for the long post, But I have a pretty good amount of time planning out the kennel/garage setup to make him comfortable. I think a GSP would do just as well in a situation like this.
