Ha ! Careful, she's training you
Same thing happened with Charlie when we first got him, hahaha. We gave him some plain boiled chicken mixed with his food to help encourage him to eat. Well after a few days it obvious he was only eating the chicken. So we put a drop or two of good olive oil on his dry food, gave it a mix and he loved it ! We did that for a few days, and he was fine to eat his food
Now he gets it as a treat. Maybe worth a try, good for their coats too !
