Yesterday morning Sophie decided she didn't want to eat and she is usually a chow hound. She is normally fed 3x per day as she can't go too long without food as she will barf bile. Lunch time I decided to try rice and chicken and she ate that lunch and dinner. When she goes to bed she gets a few kibbles in her bowl in the bedroom and she polishes them right off and she did that last night. I thought all was over but this morning she wouldn't even eat the chicken and rice!! She seems pretty normal except she isn't bugging for something to eat, which normally she does a lot. She was to the vets 2 weeks ago for her shots and a check up and all seemed fine so I have no clue what to think. Any ideas?
