How many puppies in a lhasa apso litter?

I have had 7 puppies as a maiden (first) litter. I have known one female to have 9 puppies for each of the 3 litters she had. average is between 4 and 6, however it can be as little as 1 or 2 or as big as 10 or 12. It all depends on the female every dog is different.
