Picky eaters are more often made than born. Adding goodies and begging your dog to eat are usually counter-productive. Fix the food, put it down, and walk away. Give her a time limit (say ten to fifteen minutes) to eat. If she doesn't eat in that time, pick the bowl up and don't give her anything until her next meal. Also, make sure you aren't overfeeding. At a year old, she should be on two meals a day, with about half her daily intake in the morning, half in the evening, and training treats taken into consideration when figuring amounts.
