read the force fetch thread.....have fun with him until he's about 8months old. People, you're gonna have your dog for years! no need to think the really good dogs you've seen started training when they were 12 weeks old. Sure, little things but, man alive can you mess up a dog at that young age!
have fun, fun and more fun with them until they grow up a bit- go on walks, not long hikes, play in the yard, take them to the pet store, meet people and have more fun.....
