I use a carnation mix, which consists of 1 small tin of carnation mixed with equal quantity of cooled, per-boiled water, 1 egg yolk, and few drops of Abidec infant vitamin drops. Glucose can be added too. I have reared lots of pups on this, either as a supplement for Mum with little milk, or as the only source of food (as in my current litter who are 6 weeks today). Pups love it - the current litter love it so much they are refusing to go onto solids! I started using this a few years back, after a conversation with a friend, whose Vet had been doing research in neo-nates death, and found that almost all of the bottle fed pups he did a PM on had a colleciton of milk powder in the lungs.
Of course, this was not necessarily the cause of death, but was probably a contributing factor in lots of them. So after hearing this I stopped using puppy milk formula and used the carnation one. It has the added advantage of being readily available - you can just buy one can to have in, just in case, and then if it is needed buy lots more! As the pups get older, if they are still on bottle feeds, I add an extra egg yolk to enrich the mix.
