Each breeder will do it slightly different. My way is as follows:
1. At approx 2 weeks when the eyes open and they are up on their feet. Still give them the bottle 3-4 hourly but introduce a suitable puppy porridge mixed with water (before mixing the water should be boiled and allowed to COOL and mix whilst it is still warm), the consistency should be like a runny porridge. Offer this to the pups 2-3 times daily to begin with. Some pups may not want it, others will most probably dive in.
2. After feeding each pup will need cleaning and drying. I use unscented baby wipes, just throw away after use, and a clean, soft towel after each feed. If they are not dried well they will cry and grizzle until they warm up again.
3. If they pups are taking this well in another 2 days I offer the puppy porridge 4 times a day (they will still be receiving the bottle 3-4 hourly).
4. At three weeks of age I have them on 5 meals a day, still with the bottle (pretend the bottle is mum) by now if you give the last bottle at about 11 p.m. they should be able to go until about 3 a.m., then start breakfast at about 6.30 - 7 a.m.
If they are crying in the night you will have to get up and bottle feed them.
Gradually increase the amounts of food being given as per instructions on bag. The weight gain should be steady.
5. Don't forget to worm them - consult your vet when to give the first worming as they have had a slow start no sense in upsetting them. I use liquid Panacur, some people manage better with the paste. Under normal circumstances I worm at 2, 5 weeks and just before them leave me during the 7th week. Your vet will supply you with the wormer (although it can purcahsed at a reasonable cost online). But you will not be using that much with 6 pups, so should not cost too much from the vet.
As the amount of solids is increased and as they get older you can lengthen the time between the bottle feeds. I like my pups to be completely weaned by 7 weeks of age at the latest if on mum, you should be able to do this much quicker with bottle fed pups, just see how it goes.
Hope I have not forgotten anything.
