5 years Old?? Why did you wait so long?He might not do as well as if you would have started when it was a pup.I think I would spread my Decoys out in the pond and just pitch the dummy out in them and let him go get it.They see where the bird falls and that should be it.I would take him to Cooke Canyon and do some shooting over him. Its good to knock the dust off the dog before hunting season.
I wouldn't recommend the fireworks. We throw a pissload of marks ( bumpers or birds) several very night until the dog is crazy about retrieving. Then we have a second person start throwing the marks anywhere from 50-100 yards away. Again several every night that you can and gradually introduce a shot with a blank pistol in the field with the remote gunner . Throw the bird then shoot and the dog will be focused on the bird. As far as the gun as mentioned above just have it around and work the action while doing other things he likes.
