Generally, it takes between seven and 10 hours for a dog to digest food, but the many variables mean that only your vet can tell you how long it should be taking.
Feeding an adult dog twice a day is generally optimal. Divide your dog's recommended food intake into two and feed him in two separate sessions. His food packaging should indicate a suitable daily amount. Once you give your dog his first meal of the day, aim to feed him for the second time between 8 and 12 hours later.Morning and night meals usually are a good idea.s your puppy gets older, you should slowly cut down on meal frequency. A young dog should be eating twice per day -- like an adult -- when he's between 12 and 18 months old.
