First, all labs are hyper, and they will be until they are about 7 years old. Thats just how it is. Every now and again you'll get a chill one, but then you have to try and light a fire under them. Goldens are the same way.

As to the dog wanting to retrieve, you cannot teach him that. Its either there or its not. You can foster is, and make it grow. And you can make any dog fetch once or twice, but wanting to do it more than anything is just in them from good blood lines.

As bees knees wrote, obedience is key. It doesn't take several hours out of the day. Infact, if you were spend several hours on it, the dog would just tune you out. They have attention spans sort of like kids do; 15-30 min is about it. But you have to do it EVERY DAY. Twice a day is even better. 15 min in the morning, 15 in the evening. Thats all it takes, but you cannot skip days.

If your dog is hyper, and just doesn't want to have anything to do with learning, then you need to just walk the dog. Sap some of that energy out. Throw some fun bumpers or whatever. Nothing hurts when it comes to positive activity with your dog. Almost nothing anyway.

Assuming I have 15 min to work with Dutch, I'll take him to the football field at the end of our street. I'll let him outside and he will go water the bushes. I'll call him to heel and off we go. As I walk him down to the field, I'll have him heel halfway there (its only about 300 yards). As soon as we get to a grassy area near the parking lot (its a practice pee wee field), I'll tell him OK, and he can go sniff around and he usually makes a puppy pile out in the woods, which is nice of him not to drop it in the foot path. Then he already knows where to go. Right to his spot in the end zone. He will run out, sit, and lay down. I'll walk up and toss one as far as I can. He will watch it, then I'll send him. We will do this until he starts to get tired (depends on the heat mostly), or until I have to go.

As we walk back, we do obedience. He stays at heel, and I'll stop walking. He should sit, and he does. I'll command sit, he should sit. I'll walk off a bit. He will stay. I'll command come or heel, and back he comes to me. He knows the deal by now, but we still do it anyway. Ever notice that pro baseball players still take BP before games? Even though they have swung the bat millions of times? Same principle.

Doesn't take a ton of time, just lots of little time periods. Dogs cannot train themselves.
