I never planned on moving back, but the Cottonwood/Sedona/Verde Valley area is my old stomping grounds as a kid and teenager.

A Comply or Quit does what @Marcus Curtis is suggesting.I think the lesson learned is that you have to remember that you are dealing with teenagers, possibly in their first away-from-home living experience.  

Don't get me wrong, I'm sure you are a great dad, but if he is anything like I was, I was a typical teenager who was thirsty for new influences in my life (not just my parents). 

Specifically I would want to hear that the dog is going to be going to a training program from a well established dog trainer, and that they have real clear goals for what the dog is going to be trained to do and by when.The other thing to consider is the age of the dog, a German Shepherd who is 4+ years old is going to be a lot calmer than a dog aged 1-3, those are essentially the Teenage years for the dog, and when most problems with a dog are going to occur, I would not disqualify or accept a dog solely on the age, however just keep this in mind.

We are slow to grow at this stage in our life as we just started a small business,  I have a high pressure W2 job, we’re in the middle of a slow live in flip and we have teenagers,  live in California but have our rentals out of state that we self manage. 

I guess that's the world we live in, I can no longer hire a teenager in the summer to cut the lawn

@Heather Rudy I would watch a few youtube videos and see how easy it is, then decide if you want to DIY, which is what I would do especially if you have some teenagers sitting around.

No teenager has ever asked to mow my yard.

Maybe I'm not being fair to the kid, but I also see teenagers with no sence of responsibility at all and when I was their age, I had already borrowed money from a lender and paid it back.

The one I'm watching now even has a meth head dead-beat husband that left the purple-haired wife for her niece, and naturally the daughter is a pregnant teenager...Can't... stop... watching... so horrible...
