Allow the birthing to take place naturally, offer her water but no food (she would most likely throw it up).
It will be normal for her to pant heavy and whine or whimper. Some dogs shiver. Active labor can last from 2 to 12 hours.
Each puppy will be born encased in his or her own amniotic sac; the sac may break or it may to be opened. It is canine instinct for the dam to tear it open using her teeth, if she does not do this, you must carefully assist.
Crying and whimpering during labor is normal, however afterward the dam should be peaceful and rather quiet. Signs of distress after giving birth could point to an emergency issue and the veterinarian should be contacted ASAP.
Puppies may be born in rapid succession; though there may be up to 2 hours in-between each pup being pushed out.
It's best to let nature follow its course, only stepping in if there is a true need. You may need to gently help pull out the puppies with extreme care. Have your vet on call, in case a pup becomes wedged.
If the dam does not bite the umbilical cord, it should be "cut" by using sterilized thread. You will tie the thread around the cord and pull quickly on both ends.
Once the puppies are born, the mother will clean them. Her cleaning will help to stimulate their blood circulation. Once all of the puppies are out, the dam will push out the placenta. Once this is done, the birthing process is over. It may seem a bit disturbing, however sometimes a dam will ingest the materials that are pushed out of her including the amniotic sac, umbilical cords and the placenta.
You may need to use the suction bulb to take mucus out of the puppies lungs and throat the dam does not clear this herself.
Keep a close eye on your Pug and the puppies. Make sure that the puppies are breathing
; if their tongues are blue, this means that they are in distress. In addition, they must be able to reach their mother's nipples to nurse; you can gently move them over to this spot if they need help.
In the event that a dam seems disinterested in her pups or shows any aggressive behavior
, take the puppies to a warm, soft and safe area and supply them with much needed milk. This will be administered using a dropper.
Allow the dam to rest as much as she needs after giving birth. Most dogs bounce back fairly quickly after giving birth. Look for red flags signs such as bleeding, weakness and fever. These are red flags to bring her to the veterinarian ASAP.
As the weeks go by, she will need you to "babysit" her puppies more and more often as she takes much needed breaks.
