Met two crazy guys in Plentywood pheasant hunting that had 4 upland dogs, but the fifth was a cur that resembled a lion (color, looked like he had a mane). Anyway the point is the trainer (owner) said of all the bird dogs he's had over the years the cur did as good as any flusher he'd ever owned and as far as stamina it was head and shoulders above the rest.
The dog was nice, but with all his scars from lion, bear, coon, possum etc. he looked scary.
Heck Fred, start working this one with the Griff and you might have a tag team.
