?? We've had up to 5 dogs at the same time, they all have had their person. They have had to share of course and some are more bonded to us than others, some like spending time with the other dogs. They all are safe, loved, vetted and well cared for. I don't feel like any are missing out on anything.
It's not that they're necessarily "missing out" on anything. If your dog never leaves the property, doesn't bother anyone, and has plenty of room to exercise, is fed and safe and vetted, there's nothing wrong with a dog being "doggy" and not particularly bonded to any human. In fact, some dogs work better when they are not too bonded to humans (Livestock Guardians, etc).
But some of us want more than that from our dogs, we want a stronger bond, a dog we know will trust and respect us. A dog we can take anywhere, anytime, and we know it will behave itself. To say nothing of the dogs that have real-life jobs like SAR, Law Enforcement, guide work, etc. That takes work, and if there is little to no bond between the dog and the person, it takes a lot MORE work, if it works at all.
In fact I remember reading about one of the guide-dog organizations, early on in their experimental raising and training of guide dog puppies. Pups that were raised with another dog, either their littermate, parent, or other dog close in age, consistently failed the guide tests. They simply didn't care about humans enough to work for them.
If you don't need or expect that from a dog, then you can get away with letting them be more dog-oriented than human-oriented.
