battue
I'd be willing to bet most "paying customers" wouldn't know what a good bird dog was if it bit them in the ass. Exposure to game is great but doesn't always equate to training or how a dog acts/handles or what traits a dog has or doesn't have.

Ranch/preserve dogs are among the most out of control dogs I've ever had the displeasure of hunting over.

40 coveys a day? That I'd have to see 1st hand lol
