this has had me thinking since yesterday. What can I say, I had insomnia last night
and had to ponder on something.
I think this comes down to researching your breed. It happens to a lot of people, so I'm going to hijack this thread and your comment to illustrate a point.
Labs are retrievers. They are bred to follow orders - go there, pick that up, gently bring it back to me. They are bred to have soft mouths, so they won't bruise the meat of the birds they are retrieving. Sure, it takes training for the dog to recognize the full potential and some dogs are just NOT going to have that soft mouth. But, generally speaking they are naturally a little more bite inhibited (naturally gentle with their teeth). And of course, all pups are mouthy. That is the way they know how to play, communicate, basically how their world works.
Herding breeds, on the other hand, are bred to boss other animals around. They work closely with their shepherd, but when it comes to the sheep, the dog has to make them do things. That is the point of the dog and if the sheep doesn't listen, the dog bites and nips and DRIVES it to do what it wants. It even varies by the individual breed within the herding group, so you have to know exactly what background you are dealing with to know how much effort you are going to have to put forth to control it.
They start with the stare (Border Collies are the Jedi Masters of the STARE). Herders bark and nip at the heels of their herd. If something is running or leaving the group, the natural response is to nip and bite until it returns to the group. That's why many parents believe that herding pups are aggressive. Kids naturally run around and all over the place. They don't "follow orders". They are naturally much more prone to nipping than other breeds - it's what they are bred to do. So, when a sheep (or person) doesn't do what the dog thinks is proper, the nipping escalates from air snaps at the heels to growls and actual nips.
I'll add GSDs as a special case under the herding group since they practice what I call "full contact" herding. They nip of course - GSD people actually refer to them as landsharks and it's not uncommon to spend early puppyhood looking like a human pincushion. But, when it comes to working sheep, the styles and genetics are completely different than most dogs. It is actually recommended to train with an instructor who knows GSDs or they think the dog is going to kill sheep. The GSD will circle (moving fence is actually their job) and keep the sheep in a certain area. Strays and stragglers are nipped and herded, like all dogs, but if that doesn't work GSD will move to the body block. That means, they will head off the runaway sheep(child) and tackle them and then herd them back to the area. If that doesn't work, the GSD isn't above grabbing a big mouthful of sheep(child) booty and dragging them where they are supposed to go. So, that is going to be something to keep in mind when the puppy comes home and to prepare for to stop the behavior and teach the right way to deal with people. There is also the fact that GSDs are genetically wired for civil aggression, that means they have to be willing to bite people. They wouldn't be much of a police dog if they had the temperament of the pit bull and never wanted to set teeth to human.
In the OPs case, it sounds like the pup has taken advantage of the lack of structure to set up his own little kingdom. He is keeping the subjects in line in the only way that dogs know, nipping and growling. A growl is a warning "hey, you better shape up" That is why a trainer is important, someone to see hands-on what the dog is reacting to and how to fix it. Also a good argument for purchasing a dog from a good breeder. They will honestly tell you the temperament of your pup and will match you with a dog that suits your needs and experience. They also provide a source of emotional support, training advice, and personal experience with the breed to help get your pup the best start possible in life so that problems like these don't end with the dog dumped at the shelter or put down.
