I fed my cocker a handful of Beta puppy softened in water four times a day initially, you will get to know how much to feed by whether or not it leaves any.
I reduced it to three times a day after a couple of months and fed a little more as she was growing. After six months try going to two larger feeds a day.
My dogs are always split fed, half their ration in the morning, half in the evening.
There is no hard and fast rule as dogs differ so you will have to monitor and adjust as necessary. If you find there are leftovers to begin with you can assume you are feeding too much. Little and often is the way to go until you get to know the behaviour of the pup. Try to take up any uneaten food after fifteen or twenty minutes, less time as the dog gets older, to avoid the dog becoming accustomed to always having food down to go back to. This will encourage the dog that it should eat it's fill in one go before it's pack leader (you) takes it away.
