I agree with Britster. I went through a period of time with my puppy that I was actually hand feeding her because she wouldn't eat and I thought it was because she was "afraid" of her bowl...I went through a fortune in bowls
But NOPE, she had me fooled!! She just liked all the attention. I did the whole put down, leave down for 20 mins, pick up until the next meal no treats in between. Nearly killed me
(She was ready to eat by dinner) But she started eating, and has never refused a meal again until she was very sick...and that was how I knew she was sick! I think you should contact your vet to see how long he feels the puppy can go without food...yellow bile is usually a sign of an empty tummy...and then BITE that BULLET....and make sure no-one in the family sneaks her any food...and that she doesn't steal from the cat or beagle. Best of Luck...I know holding out is very difficult thing to do, with those soft brown eyes, and little bodies...and and and...
