Not sure how it is in Arabia, but here, usually when we say "milk" we mean cows' milk. Cows' milk can cause your pups to get diarrhea and that can dehydrate puppies this age at an alarming rate.
Goats milk is a better option.
I let my pups drink off the mom up to eight weeks, but at 3-4 weeks I start giving them kibble mixed with hot water (let it cool to luke warm) several times a day. But as they are drinking from the dam, they are still getting milk.
