Dog food or table food?

My husband's concern for the dog food is not the cost but the availability. What if the dogs are used to eating dog food and suddenly the supply was cut? But in the morning, we still give our dogs canned dog food that is prescribed for the kidneys. Actually that KD type dog food is a big help in giving a good texture of poop - not wet but not constipated. Wtih other meals, we give our dogs boiled meat like chicken, pork, beef but more often we give them fried or boiled fish. They are used to eating that menu and we get no complaints.
