Through a good cooperation with your Weimaraner, you create a relationship, where you can work with basic obedience, which again constitutes the basis for every other kind of training.
You can train a lot of different disciplines with a pointing dog. Several of these have hunting as their object. See DWK for a good overview regarding different options. 'Uddannelse af weimaraneren til jagt' (Danish).
You will meet a lot of incredibly helpful people who gladly will spend time helping you and they represent a goldmine of experiences. You will get a lot of different - and even opposing suggestions on how to approach training. Be humble, listen, learn and pick! Breeds are different, and dogs are different within the same breed – and we humans are different too; what works for me might not work for you.
