My girls Brandy and Cecil did the same thing when they were about five months old. Our trainer told us to put them on Bil-Jak puppy and they just ate it up. Then when they were six months old the vet told us to start them on a reduced fat food and we got the Bil-Jak adult reduced fat and they loved it. They are now nineteen months old - getting more grown up LOL!!! We had been giving them a tablespoon of Purina Pro Line weight management turkey and vegetables with a little rice or their remaining kibble. We have been doing this for six months. Now they, especially Brandy, will not eat her morning kibble (2/3 cup) each dog. Also, left a lot in the evening (2/3 cup) each dog, to mix with the wet stuff. Now Brandy just waits to have it mixed in the evening. The only way I could get her to eat her morning kibble was to hide it in the toy box and let her adventure for it. This morning I gave in and put 1 tablespoon of the moist in with the 2/3 cup kibble. Presto...we ate. Both girls ate most of their breakfast. I think they get tired of the same old thing too, so maybe adding some good moist food ( a tablespoon) will do it. My girls have held their figures and weight by doing the recommended reduced fat and weight management thing, but I am sure some flavor assists in the enjoyment. Would you want the same thing day in and day out without a littly variety? Give that some thought and see what you think.
