Go to your vets office and ask them for a syringe that they use for diabetic dogs, They are real small and will work fine for your puppies. That's waht I always use and Nurturall is probably the best milk replacement. It, too is what I use. I work at a vet s office and that is what we reccomend to everyone. You probably won't need any of it, but your right to get prepared early. Good luck with your babies, just sold my last one out of my last litter, so thanlfully for now I'm beyond what your just getting ready for!
Let us know when they are born.
