Thanks to everyone for their responses. We got our new baby's labs today, and sadly not the greatest news. Might explain some of her lack of energy in afternoons after eating

on top of adjusting to a new home.
Need words of wisdom before I/we contact breeder and decide on course of action.. I am somewhat devastated. Especially after losing my dear Jasmine a little over a month ago.
A few facts before the labs. The breeder gives a a two week window to make sure all is a "good fit" with her babies. If not, she gives us option of picking another pup, or getting our money back. We have had our baby since Saturday (11/11, and of course started to fall in love with her. Her vet exam showed grade I luxating patella's and retained canine baby teeth (which will need to be removed at some point). She was spayed by breeder's vet 3 days before we got her.
Her labs show: Glucose 116-slightly elevated, bun-23-normal, total protein 5.3, slightly low (5.5-7.5), Alt 13-slightly low (18-121), AST and ALP normal, bilirubin- normal, Bile acid pre 1.2 (0-6.9) Bile acid post 34.2 (0-14.9). My vet is on vacation till next Wednesday. These were called to me by another vet in office who has not seen Callie. I would think based on all my reading next medical step would be to get an Ultrasound at minimum.
