What type of mixer biscuit should I give with lilys kitchen organic puppy wet food tray please? He is having half a square tray on a morning and the other half at night. They are 150g trays. He was on applaws but I cant get it now, am I feeding him correctly anyway? Need help as he is always hungry, I didnt know but he was just having all protein with applaws, is this ok to do or should he be having a mixer biscuit. Help please
