Chris,
I talked with one of his buddies last night for about 45 minutes. I asked the same thing. Basically, Josh wanted to bring attention that the Danes were originally boar hounds from his research. Obviously, it draws attention to him as a hog hunter. It would be like me saying I hunt blueticks, or just calling them "Over rated dogs". Same thing, just phrased differently.
I was also told that Josh receives a lot of ribbing from his buddies on the "American Boarhound" name. They all come up with special names for their dogs just to pick at him.
