This summer it occurred to me that I had only a vague idea of how long a bag of my dog's kibble would last. I measure her meals (a bit less than one cup in the morning and the same in the evening) so knew how much she ate each day but the food bag is measured by weight rather than volume.

Can't plan responsibly for her survival if I don't know how long her food supply will last. So when I opened the last bag I marked a calendar.

She eats Wellness Fish & Sweet Potato. 30lb bags.

I now know that a 30 lb bag will feed her for 9 weeks, at her normal rate of consumption. Longer than I expected.

I'm in the habit of buying a new bag when her old bag gets down to half.

Still don't know how much water she consumes, I just keep topping off her water bowls. That's the next research project: starting the day with a gallon jug of water and tracking daily consumption. Will vary greatly, of course, depending on weather and her activity level.

Does everyone here have a handle on how long their pets could survive on the pet food they have on hand?
