I used James's first edition as my main source of knowledge to train my first two Boykins in 1994--at that time I knew of no one who was hunting Boykins in the uplands. They were all just dove and duck dogs. 4 Boykins later, I still use Hup as my knowledge base for total training. Hup covers your basics, the retriever work and the upland work. If you hunt your spaniel In Dove fields in the fall, then the Duck blind and chase pheasant, grouse, Huns, etc in the winter, this is your book and single best training manual. Over the years, during off season, I've run my spaniels in UKC-HRC retriever tests set up basically for Labs, plus AKC upland hunt tests for flushing dogs. Hup will get you started with all that activity also. If you can find the hard cover 1st addition, get that, otherwise the paperback 2nd will do fine--since it is basically the same.Here is two year old Hunters Rest Artemis running 5 for 5 titled AKC Senior Hunter and Hup trained.
