That may wear his coat down. Not something I'd want to leave on(but I like my dogs naked!)
When I put a training collar on my dog, I let him know what we are doing, the collar tells him as well...fursaver is usually the tracking collar and the prong is obedience. A harness or agitation collar is for protection(prong as well).
I would use a rolled leather collar if you want to leave one on him, it'll be easier on the coat.
I've seen pics of dogs wearing 2" collars as the 'daily dress' and it just looks odd and uncomfortable. I don't think I'd want to leave a fursaver on either, too many spots that can get caught up.
