Kind of weird question, but I have a glass measuring cup and a plastic measuring cup both similar to the links below. A cup from the glass one holds quite a bit more dry food than a cup from the plastic one.
Is there a reliable way to make sure I'm giving my dog the right amount of food? Does anybody use a scale or anything that gives an exact weight rather than just the volume?
