Mostly by smell.
Because the puppies get cold.
the number of puppies a dog will have depends on the breed, and size of mother dog in question.
The mother might die unless the puppies are surgically removed.
Yes, but not just the mother but siblings and also its quite easy even humans can tell.
the other puppies will be born and the dead puppy will simply just come out.
You see the puppies around the mother.
It depends on the breed
you cant have puppies!!!!!!!!!!!
Right after it gives birth. ;)
No, the puppies will open their eyes on their own in 7-10 days.
the mother dog will start to make the puppies independent by "being mean" to them. when she is gone the puppies will need to know how to get along without her. when she ignores them they are forced to do things on their own which makes them independent.
It is not recommended for the mother dog to nurse her other puppies after consuming a dead puppy. This can lead to health risks for the remaining puppies, such as infection or toxicity. It is best to consult a veterinarian for guidance in this situation.
