I am a student Veterinary Nurse and we tell clients not to give their pups milk,
as soon as they are weened off their mum they can have water. aslong as they are eating well and putting on a suffiecient amount of weight.
Many breeders tell you to give them puppy milk or goats milk but really its not very good for them so try and get your pup off it asap really. It wont cause the pup any harm to have the milk but its not that good for them really.
