Rufus was good until he caught his first rabbit about this age. Whatever you do take the advice of the good people on this site. Use a long line, and stick with it. I did not, and am still paying the price with my hunting monster who is 4. Rufus was never food orientated as a young dog. Various trainers, including 1 paid for by a friend as my birthday present wanted to use citronella collars and all kind of techniques, none of them worked, because I was not as interesting as what he wanted to do. I now accept that he will only be off the lead in 3 places where I know he is safe, and will come back because he knows the area so well. I would not want anyone to go through what I have been through, both with contrary training advice, and the stress of his hunting. By the way, since 16 months his recall in a confined area is perfect, as are his other obedience commands, and he is good at agility with oral commands. Even at the start of the walk off lead he will come back when called. It is as soon as he gets the scent of a rabbit, squirrel, pheasant, fox, deer, mouse, rat etc etc that he is off. He always comes back, eventually.
