do you feed them once or twice a day?? With a small dog, I would suggest twice a day (and it would probably be easier for her to eat a smaller amount). Also, if you do that and if you feed dry dog food; if she doesnt want to eat, try some canned food to entice her to eat. But overall, if she is not losing weight, and the vet says she is ok, then it may not be to much to worry about.
