<human>: I've had my dog since he was a puppy. He is now 3 years old. I'm very attached to him and care very much about him.

I recently graduated college and accepted a job. The job requires 80% travel out of the year. While I'm traveling I'm expected to work 12 to 13 hour shifts, 6 to 7 days a week.
I've thought about hiring a dog walker for when I travel. I've gotten advice from one co-worker who travels with his dog - he's able to find dog walkers almost everywhere he goes. There are plenty of pet friendly hotels. However, his dog is 12 years old and not very active.

I just feel terrible about leaving him alone in a hotel room for hours while I'm at work. Yes, I would have a dog walker, but would this be enough for my boy?

His happiness matters so much to me. I would do anything for this dog. He has saved me from some very dark places and I do not want to "abandon" him or "give up" on him by giving him to another owner, but it may be the best thing for him.

More information - the dog is very well housebroken and has a bladder of steel (can usually hold it upwards of 7 to 8 hours or longer if necessary), he doesn't chew up anything, only barks when I'm around.

Anybody's advice would be helpful. I don't want to feel like I'm giving up on my boy if I were to give him to someone who can give him more time and human interaction.
