If you have pets you care about that much, take them with you or don't do the things that require you to be away. So much is about "I want" and refusing to accept reality. If you are away from the house for 12 hours a day then having a socially intelligent pet such as a dog is an experience you will simply have to do without in your life. If you want a pet, get some fish or a hamster.
...the hell? The discussion was about cost, and it wasn't an invitation for your strange take on what pet ownership looks like. Go spout that junk elsewhere.
I will continue to do things that require me to be away for periods of time, and I will continue to pay whatever I have to so that things work well. I feel no shame about this and the dogs are healthy as can be.
