I am in the process of searching for my first started dog. It will be used primarily for waterfowl hunting and as a companion for my 3 year old son (and me). I am looking for the best trained male I can find for around $2,500...but I'm not sure of how to evaluate the dog when I find it. How do I keep from getting screwed over and ending up with a dog that doesn't do what I want? Thanks in advance for any pointers.
