Hi..
I have a brand new 10 wk. old puppy I got on Friday...She wasn't concerned on eating at first either...
It takes encouragement because of the new surroundings. I take Sophie and hold her with some food in the cup of my hand. She likes that...
I know..could wind up spoiling her..but she now eats from the bowl and my hand!
Good luck to you..keep working with her..and possibly let a vet peek at her too.
