Dogs should eat at least two meals each day, about 12 hours apart. But a breakfast, lunch, and dinner schedule is an equally great option. If more than 12 hours elapses between meals, the stomach can become hyperacidic causing nausea.
Dogs can go for a few days without eating anything. Just be sure they are drinking water. It is normal for a dog to turn down one meal every once in a while. Dogs, just like people, aren't always hungry.
Most dogs can go three to five days without food, while in some cases they can survive seven days or more. However, if your dog won't eat for more than two days, we recommend that you talk to a vet. A bigger issue is water intake. Dogs can go far less without water than without food.
The number of meals a dog eats per day depends completely on the family schedule. Dogs should eat at least two meals each day, about 12 hours apart.

Dogs can survive for up to five days without food and up to two days without water.
Most healthy dogs can go up to five days without food, though that number is only true if your pet is still drinking plenty of water. Some can even go up to seven days without, though you should never let things get that far without taking your dog to the vet.
Puppies, unlike older dogs, don't have fat reserves. Therefore, they can't go longer than 12 hours without food. This is particularly true for toy breeds that are prone to hypoglycemia (a drop in blood sugar), which can lead to serious complications. Puppies are also more susceptible to dehydration than older dogs.
