Hello. I bought a Cane Corso yesterday and he is very small.(haven't taken him to the vet yet so not sure of exact weight) The litter was pretty big, (13 pups) and The breeded said that the mom had to have a C-section a week earlier than the due date and that contributed to all of the puppies small size.. question is, does that mean he is going to be small or will he still be a regular size Corso? Thanks!
