Hi, when we had our first and only litter of poodle pups in Nov i had bought a cardboard whelping box, a heat pad, had sterilized scissors, some surgical gloves, some ky jelly, and a thermometer. I think that was about it really, had no probs thankfully though.
Also had some scales, notebooks, clean towels, bowl of water nearby.
Expect I should of had a lot more really but my breeder (whom I kept in touch with re the breeding etc) who had 30yrs of breeding poodles told me this would be all i'd need. besides................having the vets on standby (which I did) her phone no handy too and plenty of coffee to drink if it was in the middle of the night.
