RE: Vizsla Question...
I would like to suggest a couple of books for you to look at and I would suggest buying instead of barrowing or checking them out from the library. The reason I say that is because the books can act as great reference tools to have on hand, you can go back and read them again. If you can't remember what the book said about something or you have a question about a situation you can refer to the book and see if it addresses your questions.
Gun Dog by Richard A. Wolters a book, written in the earlier 1960's I think, that is IMO the pointing dog training bible. It is still printed and has stood the test of time. I believe it was a revolutionary training book that is in part the basis for most modern training methods when it comes to pointing dogs.
Tarrant Trains Gun Dogs: Humane Way to Get Top Results by Bill Tarrant
Bill Tarrant was a gun dog writer and editor for Field and Stream and very knowledgeable about dog training. Also he wrote several other books of which I have not read, however, I am sure they would be worth ones time to read and purchase as well
Now the two books I have suggested will contradict one another from time to time but the basices are similar. Wolters suggests a more hard hands approach then Tarrant as the title of Tarrant's book suggest. I don't believe in adopting just one training method because your dog will don't always conform and it is good to have other methods to draw from to get your dog to where you want it to be.
