It is possible for to have a problem with her tummy that makes her not want to eat i would get her checked out for her sake and your peace of mind ===as far as eating goes how many cookies does she get during a day ==some dogs are pickey eaters and when you change food on them they just wont eat it what food has she liked in the past try a can of it and scince you know she eats the cookies grind 1 up and sprinkel it over the food to coaks her to eat or use any thing you know she likes also try cooking a extra pice of chicken no spice no tomatoes or onions chop it up into small pieces and hand feed it to her and if it workd for a while add some to her food ===but get her checked anyway your vet may want to start her on something bland like lamb and rice or chicken and rice===good luck with her and let me know how she does
