Just want to second what Jeangenie said - Pugs very often need C sections. If you dont already know, find out from your bitches breeder if her Mum delivered naturally or needed a Ceasearean - it tends to run in families. Tt is vital that your vet is prepared for the possibility, and you know just where you might have to take the bitch. Lots of vets now dont rungtheir own out of hours surgery, and do a sort of partnership thing, so you might have to go to a strange Vets, if needed. Also you need to be fully prepared to assist the bitch to rear the pups, in my (as yet a little limited) experience of pugs whelping, 50% of them dont want anything to do with the pups at first, and you have to do all the feeding and cleaning etc, so make sure time off work etc is booked! You need to be on hand 24 hours per day.
Next, pugs dont do any of the whelping clean up themselves, it is up to you to deliver each pup if she whelps naturally, do the cord, get it out of the bag, clear airways and get breathing, dry off and then make sure it gets its first feed. Dont forget to weight and record each pup. With a litter who are unlikely to have much in the way of marking differences you need to find some means of identifying them for the growth records.
Oh, and as already advised, buy the Book of the Bitch asap. Good luck, they are a wonderful breed, but not ideal for a first time whelper! Oh, and please, dont even consider mating your girl on her next season, at least a full year between litters. (Depending on the success or this delivery, of course).
