You can get some books and videos to help you train your dog. It is not to late. The first thing I would do is start with basic obedience. Sit, here, heel, etc.
I would start exposing the dog to wild birds, I believe a Vizla is a pointing breed, you can have some big fun just taking the dog for walks in bird country, don't know where you are from.
Go to versatiledogs.com and do a search for training books, videos, vizla's as keywords. Lurk and read the threads in the training sections and the rest of the site. It can be an "abrasive" site, but just take it or leave it, ask questions if you want, but just remember that dogs and training seem to bring out all opinions and attitudes, but you can learn a lot from it.

You can also go to drahthaar.com and go to VDD group North America and find the vom Altmoor website, they have a good puppy training book and the Armbruster training manual, you can use these for help too.
