This is the book Water Dog written by Richard Wolters, a hardcover book with dustjacket.  It was published by E.P. Dutton & Co., Inc.  The book is in very good condition, with an inscription inside the front page (1976), no torn or dirty pages.  The dustjacket is clipped, and has a thumbnail-sized piece missing from the top of the front cover (see picture).

From the dustjacket:

"Water Dog is quite a bit more than "Dick Wolters Revisited," in case you're one of the many thousands that have read either or both Gun Dog and Family Dog.  As a retriever man myself I guarantee that this latest book, incorporating both Wolters' "revolutionary rapid training method" and some fantastic new thinking on retriever training, will quickly become the well deserved standard work in the field.  The new ideas cover training points that once were the well kept secrets of a few professionals - plus a few beautifully simple and absolutely right new methods all Dick's own.

Don't take my word about the photographs - thumb through the book!

Simply, Dick Wolters teaches you how to talk "retriever." And even Berlitz could listen.  And you can take just as much schooling as you need:  if you just want a really competent gun dog, Wolters gives you the easy way;  if you want to compete in the top drawer field trial circuit (and Dick does) Wolters gives you plenty of that too!  And in nice easy doses that don't assume that this is your forty-first dog and you're just trying to fill out your bookshelf.

He's covered absolutely everything you need to know - and then photographed it perfectly, clearly and logically.  Here's the real inside story made not only fun but foolproof.  This is absolutely the best book on the subject that'll ever be done.
