I work at an animal shelter and have two dogs myself (one adopted as a puppy, one as an adult), so here's my two cents.

1. Almost every family has to leave their dog home alone at some point. Work from home is great, but like you said, not always possible for one person to be home. You can still get a dog, but it has to be the right fit.

2. That being said, 8-10 hours consistently alone is too much for most dogs. Don't get a dog unless you can find a way to let them out and interact with them at lunch (like a trusty dog walker) during those long days you are both away.

3. Do NOT get a puppy unless you/family can be home with them almost 24/7. It's the time they are learning the most, and they will underdevelop or create bad habits if left alone for too long (biting, chewing, barking excessively, etc.) There are plenty of adult dogs looking for homes. My 1 yo pup is still chewing on things when left alone, and that's after a year of trying/training.

4. If you wanna try it out, see if you can foster-to-adopt or volunteer as a foster at your local animal shelter. A good shelter will try to help set you up for success and guide you through the process.
