Robert G. Wehle
I bought this book when it first came out and have used it over and over, A great book if you have a bird dog you want to train, I have several books on dog training but for bird dogs this is the best, Bob Wehle is the breeder of the famous Elhew line of English Pointers, His breeding program was a model of perfection with an emphasis on selection that was soon lost as others tried to carry the torch.
He had a great style of natural bird dog training that may not be possible if you don't have woods full of quail out back.
The ideas are sound and proven per his many champions, Good stuff. .
