Start with the basics like "sit", "stay", "come", and other basic commands at this age. You might even wait until he's seven weeks old to really get serious. Right now @ 5 weeks old I would just establish a bond and help him feel at home in his new surroundings and work on potty training. Get a book on basic training and put it to work. You have a couple of weeks to get some training info since he's only 5 weeks old but you want to start training at 7-8 weeks old. Go to antlerdogs.com and get the training DVD. This DVD is a little vague but you can call the guy who made it and he will help you out over the phone. Also, I got the book 'Water Dog" by Richard A Wolters which is a very big help when it comes to training the dog to do things that help out during antler hunting even though it is a duck hunting book. If you have any questions that I personally can help you with then send me a PM with your phone number and I will be glad to call you and talk about shed hunting with dogs. fatrooster.
