Dog owners of NYC, can you help relieve my anxiety about moving to the city with my pup?

Currently, I live in a small city. It's a 5 minute commute to work. So I go for a run/long walk with my pup in the morning, come home and hang with him at lunch, and bring him to a dog park in the evening. It's very manageable and comfortable.

But as much as I like my job, this city lacks future opportunities. It's social life is non existent. As a young professional, I need to move. NYC has all that I'm looking for, in addition to a friend base that already lives there.

However, I'm worried about how this will affect my dog. I anticipate making ~$70k a year, so I cannot afford a ~$400 a month dog walker or daycare. My prospective jobs are in Manhattan, but I feel I can only afford to live in East Willy/ Bushwick, Brooklyn. So that means over an hour round trip commute, at best, plus an 8 hour work day keeping me away from home.

I'm scared I can no longer provide the best life for my amazing dog. 9-10 hours home alone? Having meetings or obligations that might bring my back to Manhattan some nights? Is any of this possible?

I raised this dog since he was a baby, and I'm all he knows. He's the best dog I've ever had. The thought of giving him up has kept me up at night.

Please help.
