Can I ask why you'd like to know? A puppy has no need to be fed any milk at all when it comes home after 8 weeks. As a species dogs would have no access to milk after being weaned and so have no nutritional need for it. Puppy food can be soaked in boiled, cooled water (allowing the water to cool for 10 mins after boiling means it won't destroy the nutrients in the kibble) and they will happily drink water. Apart from what they got from mum as tiny babies, or the odd stolen slurp neither of mine have ever had milk of any kind and I don't think they are aware they are missing out!
