Query: chummies no longer yummy

My dog used to love these, and ate them for years. I ordered 2 bags for the pet sitter to feed her while I have been away but she noticed my dog refused to eat any. When she checked the ingredient label she saw they are no longer pure salmon but are now using fillers! I would send this food back but the return window will close while I am not home.
