I would not have a litter of puppies now with out having Dopram in the house fantastic stuff and saved a good few pups over the years (mine and others Ive told to get it)
I always have an aspirator in my whelping box,dont cost a lot and easy to use.
I got some from Boots a while back, but couldn't find any recently when I went to buy some for my whelping kit, I ended up getting them from my local £ store.
