I've never bottle-raised puppies, but I've raised kittens, guinea pigs, squirrels, a raccoon, and even an orphaned mouse once. I'll try to help until somebody with puppy experience pops in! Keep them warm-- a heating pad set to the lowest setting under a box where there is space for them to wiggle away if it becomes too hot is typically good. They'll need feeding every two hours, day and night. Very young animals cannot urinate and defecate on their own, so you'll need to stimulate them by stroking their little bottoms with a bit of damp cotton until they go. They need to both urinate and defecate after every feeding. Only feed a formula specifically designed for puppies-- Esbilac is one.

There are tiny, tiny bottles that can be used to nurse very small animals. These usually work better than a syringe. You need to be careful that the baby doesn't end up aspirating its formula, and I've unfortunately seen that happen a few times when folks were trying to feed a small animal with a syringe.

I'm so sorry you lost your dog. It must be absolutely devastating.
