The answer is that they cannot. Puppies are attached to their mother with an umbilical cord, one for each pup. If there is none, the little dog will die within the womb.
It is Naval which is where the umbilical cord was attached from the embryo in order for their mother to feed them.
Horses are placental mammals like dogs, cats, and humans. An unborn horse receives its nutrients from its mother via the umbilical cord.

No, oxygen is an odorless gas. Even dogs can't smell it.
When dogs give birth(actually any mammal in the wild) unaided by humans it is natural for them to chew the unbilicial cord,eat it and the afterbirth to add nurishment to their system that aids in the nutrients for nursing. The mother knows just how to ship it off with her teeth. Whatever is left, will dry up in time and fall off.
They sure do! Just like you cats, dogs, horses, and giraffes are all placental mammals. Placental mammals develop inside their mother. Nutrients, oxygen, and wastes are exchanged between the developing embryo and the mother through a placenta. An umbilical cord connects the embryo to the placenta. The navel or belly button is where the umbilical cord was attached to the young placental mammal. So even though you may not notice it unless you look very carefully, dogs and cats do, indeed, have belly buttons.
Yes
Yes, spinal cord injuries can lead to paralysis in any vertebrate.
Yes. Dogs get oxygen through their lungs by inhaling just as we do. All mammals do.
Dogs obtain oxygen by inhaling it through the air and traveling to their lungs. From their it goes to the bloodstream.
A group of dogs is called a kennel, pack (wild dogs), or litter (pups from one mother)A pack of dogs.
Punishment. Mother dogs will bite their puppies noses when they do something they should not, as nipping to hard when playing with his/her mother, etc.
