Yes and no... I know some lines of corgis never whelp more than 6 or 7. This line will give us the big litter occasionally. I personally don't like this many puppies. We had a litter of four once and to me that was ideal.
We have one female that we get 5-6 each time the other we have had 9 and 10, 5-6 to me is the perfect size for that small of a dog but they both raise them without any problems or assistance.
