Sorry pressed send too early!
Once the pups are eating solids they should be introduced to whatever type of dog food you intend feeding (dry complete, or tinned food, or raw/cooked meat with biscuit meal). By six or seven weeks they should be on a good quality puppy food until they are about a year old followed by a junior food until they are 18 months. As a rough guide, 4 meals a day until 4 months, 3 meals a day until 6 months then 2 meals a day until a year old, then its up to you whether you feed once or twice a day.
