First of all congratulations I think your wife and yourself have chosen wisely. He is a magnificent gun dog, well qualified as a leading contender for the title of best all around gun dog. Most Springers still posses enough hunting instincts to bring game to the bag, even the show line. Then there are the field bred dogs, and they are something special indeed! They fear no cover and retrieving comes as natural to them as it does to working Labs.
Honestly when it comes to books and DVD's they are all going to cover the same basic training and it's important for sure. I probably own a couple dozen books and tapes and take little things from each.
One of the best things you can do is get in touch with the ESS Field Trial Association and see if there is anyone close to you that you can train with.
A field bred Springer is so loaded with talent that an even not so well polished dog is going to bring home the bacon!
Imagine a poor Rooster trying to get away from one of these Rascals!
I always smile when I see Posts about Springer pups because I know the joy and memories that they bring!
