this might sound silly?

It's really good you have a willpower to take a second job, you seem quite hardworking, and caring as well! I would say it's ok, your dog would probably miss you but it's not like you won't ever see her! Take the opportunity, I think this is going to be ok. But it's just my opinion:)

..you have to decide what you really want. Live in a good way so you have to have the second job or being around your dog. Most probably she will see you not so much, but as long as she get enough time to be outside and can pop and pee not in the room, than you should go for the job and maybe look for abetter paid job too.

On the other hand I ask myself why you even got yourself a dog? Just not being lonely I think, so even the dog need some attention or she might get depressed as well. It's hard but I personally would go for the job, it's your life and after some years the dog might not be there anymore..

Thats a tough one, dogs do get lonely really quickly, is there anyone who would be at the house with he/her? Dogs who spend alot of time alone grow anxious ,but as long as you habe enough ime with her im the day then 2 jobs should be fine

You should not have a dog.
