Dakota making me a bit nervous

She had an upset belly yesterday when we got home (we got her on Sun a.m. and camped until yesterday). This morning she seemed to be feeling MUCH better and looked like she had energy and was all excited etc. went out and went potty, came in and played with a ball for a few then back in her crate...... Then she had to go poop so out again. then she wanted to go back in her crate. Then when I got up again I brought her out and got her breakfast and water and we came in and she didnt' want to eat or drink just wanted to go back in her crate..... not sure if since she was in a shelter she isn't used to being in a house??? so it will take a bit to adjust or if I should be nervous that she doesn't want to eat or drink right now???? any ideas???? She has only been in the house for about 15 hrs.......

She's been on a VERY long trip for a puppy, then to a new place, then to another new place. She's most likely very stressed out right now.

I figured that but she did soooooo good on Sun and mon at the campground. she was eating and drinking fine there. But she hasn't drank anything or eaten at all since before we left there yesterday around 5pm or so was the last time I think and it is now almost noon..... so been what about 19 hrs???? how long till I should worry?

try ringing a vet just too make sure that everything is ok
im sure like others said shes probably stressed
