I haven't read my Daily Mail yet so hadn't sees this story. The puppies are cute but pretty solidly built.
When I was 16 we got a puppy. Mum told us that it was a German Shepherd crossed with a Bulldog. She almost got it right, mum was a GSD but dad was a Bullmastiff.
When the girl is in season the boys (big, small, huge and tiny) will find a way to get to her.
Think it'd have been worse the other way round woofy. If the dad had been the rotty, the puppies would have been monstrously sized for a westie bitch to give birth too.
The owner is irresponsible for introducing a male into a house where there is an unspayed female. What the hell did she think would happen when the bitch went into season? The fact she fed the pups on eggs when the mum rejected them says volumes too, she obviously didn't get puppy milk from her vet to feed them properly.
Actually the mother dictates the size of the puppies - we rehomed a Heeler bitch recently (size of a Jack Russell) that had just had a litter by a Labrador - five puppies although one died at birth. What will be a shame is if they try to repeat the mating as they will no doubt easily sell the puppies due to the publicity. I agree with the comment from woofgang though, ignorant irresponsible idiots.
