Awesome! Keep it all fun at that age and you can't mess up. But do yourself and pup a favor and get on solid training program, needs to start at 6 months or so. Force fetch key, don't let any one tell you otherwise. I had a pro help me first few sessions on my dog, my next dog there will be more pro help involvement.
Thanks!! FF is a definite.
I assume you want to train your own dog. I would research a good pro, tell them you want to train your own dog, but want pro help, and what books/video training program to get, maybe you already got one. Or if you want to save money go HRC instead of paying a pro, HRC you could get one for free. But a book/video training program will provide a foundation and is a must JMO, coupled with hands on help from a pro.
