Put simply - it's 'natural survival' Their wild ancestors had large litters to increase the chances of a single baby surviving to adult-hood - thus ensuring the survival of the species. Domestication hasn't suppressed this survival instinct, so they still produce large litters instead of just one or two.
Survival of the species. In their evolution, with dogs born in the wild, there would be a number of animals that would prey on the young pups. Having more than one baby increases the chance that at least one puppy will survive to adulthood.
Although there is no need for this practice in domestic dogs - their reproductive system is still geared to produce multiple births instead of a single puppy.
They arent like humans, they can have up to 9 babies a litter. They are long and that's how all the babies fit inside of them. Many shorter dogs don't have many baies, probably up to 5.
Well just like humans the dogs r in little sacks and they come out at seperate times so it not very hard
Well dogs can have 21 puppies because I have seen a youtube vidio that a dog had 21 puppies but a whole litter of 21 puppies doesn't usually happen so 21 puppies is rare but dogs can have 21 puppies.
You would have 10 puppies plus the two original dogs so 12 dogs all together.
Puppies like the state Florida the best. I have studied the behavior of puppies and dogs for many years and out of thousands of dogs and puppies and species, the puppies and dogs liked Florida the best.
Dogs have so many puppies because 1. Dogs don't live as long as people do, so a dog will need more "replacements" then people do. 2. Dogs can hold more puppies inside of their womb than people can hold infants in their womb.
Its impossible. All of your dogs are puppies anyway so it doesn't matter how many trainer points you get. >.<
They are puppies who never grow up...So they don't mate or have puppies! sorry!

The dogs wish to stay a dog is irrelevnt. The animal will grow if it wants to or not. So, to answer your question; all puppies will become dogs.
All dogs can have 1-14 puppies but it is rare to have more than 8 puppies
Because eggs are fertilised and become embryos.
