A good breeder would give all new owners a feeding schedule for their puppies and it’s important to stick to this for the first few weeks to avoid any digestive issues. A puppy’s diet can be changed but this must be done gradually over the course of 4 weeks and if puppy does get a tummy upset to put them back on their original diet before asking advice from the breeder or the vet. It’s important to feed a puppy at the same time of the day to establish a routine which is another way of helping them settle into their new homes that much faster.
