Happy am I for ya...but for every dog you've had, I've got a scar that came from family pets that were left alone too much...and turned. Slated for euthanasia, I step in and work with the dogs until they've become resocialized and have learned to trust people again.
So, I'll stand by my statement. If the dog is to be left alone for long periods...16-18 hours a day for months and years on end is a long period for a dog...then the dog needs the company of another dog or two, plus whatever time you can spare. Dogs that aren't part of a pack are miserable dogs, and it's not only bad for the dog...it's cruel..and you miss out on the full dog experience. Both dog and owner lose something.
Don't know what types of dogs that you've worked with...but if you could see 3 or 4 Border Collies work a herd of sheep, you'd be amazed to watch the dogs work together. It's like a well-rehearsed ballet.
Can't argue about the boys. I'd rather manage dogs.
