Oh dear, hope you don't need one, not any help here as I do not know where you will get one from, maybe a vets wholesalers/medical suppliers. I have pups that are nearly three weeks old, no problems at all re birth etc but I had a supply of tiny bottles and teats and syrynges as well as baby bottles, the tiny ones came off the internet in a whelping pack, included in the pack were some clamps, ideal for umbilical cord if the mum does not want to break it herself, unfortunatley I threw mine away and this time, I tried everywhere to buy another and could not, they are only like blunt scissors that clamp together. Good luck and keep us posted, good idea to get some puppy formula in too, this time I bought condensed milk as I was told that would be fine diluted but again, I did not need it!!
