She will be pergnant for about 63 days. She will cut the cord or you vet should. If you do you don't want it to short. The puppies have to be AT LEAST 8 weeeks to be sold i recomend for small dogs 9-10 weeks. Her temp will drop and she will start to pant heavily before birth.
You should talk to a vet ASAP pugs are a hard dog to breed as there faces can sometimes make it so they get stuck in the birth canal. My moms friend breeds them and of the 2 litters she had both need c sections. (she stopped after that) If there is no vet help you could lose the mom and all the puppies.
I raised Pugs, pretty unsuccessfully for about 5 years. No c-sections at all, but I still lost a lot of puppies, because I had bad mothers. Mothers that would squish their babies in a heart beat. Pug are difficult to birth even naturally. They have extemely thick sacks and cords, and because the mother's face is so unnaturally flat, they can some times have a very hard time getting the sacks off. You will probably need to assist, and this is not for the faint of heart.
As an experienced dog breeder, I would say these are a difficult breed to raise and you should probably beg the stud owner to help you whelp this litter.
Puppies should not LEAVE before 8 weeks but you had better start advertising them as soon as they get their eyes open. Just ask for a deposit to hold the puppy until it is 8 weeks.
Boxers are like cookies you can't have just one :)
I also sugget getting in touch with the stud owner or other experinced breeder who knows about Pugs specifically. Toy breeds are a harder group to whelp in general anyway, but the Pugs can present a bigger challenge for many reasons. As the others mentioned...the heads of a pug puppy are larger and rounder than your average puppy, which makes it very easy for them to become lodged in the birth canal. This requires an experienced person and many times a vet to do a c-section to get the pup out. Your other main issue is that pugs...due to their flat faces, are not able to get ahold of the water sack to break it open. You MUST be present to take care of opening the sack for them as well as cutting the cord. As in every breed, being there to help is important also to be able to tend to the weak pups, help them get started breathing if needed, removing fluid from their lungs, etc
They average 63 days in their pregnancy just as with any breed. This is only an average and you should be prepared for them to come as early as 5 days and as late as 5 days. This can also have exception to the rule....tricky stuff really, lol.
How far along is she now? Do you have someone who can help you through the whelping?
People are like slinky's, not really good for much. But its still fun to push them down the stairs.
My pug just gave birth to 5 babies yesterday they are pregnant 63 days and pugs are a hard breed they come in double sacs and they are real thick I know this because I have to help my mothers when they are giving birth I tear them out of the sacs help clean them up I have only had 1 c-section I have slept in the recliner next to sassys bed the last 2 nights there is alot of work that goes into raising puppies and alot of sleepless nights.
this has all the info you could possibly need altho it would be much better to have an experienced person with you. You really should not be breeding dogs when you know nothing about it. http://www.debbiejensen.com/
