They are puppies. hide Runaway clap call them to get thier attention or get on your knees or lay down to get their attention there are 2 don'ts 1 don't chase them becuase that will be detrimental in retrieving they start to think of it as a game the other is stay low so they are not intimidated by you. Dogs don't think of equality they think of dominance (Alpha) as they get older they will start to listen be patient and calm. Look for A Richard Wolters Dog training book he has several out I like Gamedog and Waterdog he also has family dog.

As for the second question you have you need to assert domanince make him under stand you are the pack leader not him. As he is chewing his bone or whatever he has even his food take it away if growls pop him on his nose( not very hard enough to surprise him) and tell him NO!! in a growling voice and don't give him back the bone or whatever else.Now when you go back later to take the bone take it and if he doesn't growl give it back to him and praise him in a pleasent voice.
I do one other thing with my dogs that are dominent I put them on their backs and put my hand around their throat and stiffen it ( I don't choke its there to represent another dogs mouth) Then I put an mean face and growl once they stop struggling (submission) and relax I let them go as reward. after few times of that they relize whos the boss
and I express this enough BE CONSISTENT IN YOU TRAINING.
