id rather have a nice fat pup you can see a difference in them when they grow had a litter off pups resistantly kept 2 pups back all the same size when there owners chose them the two i kept made big dogs 28" + now the others that are local that weren't as fat as they should be while growing struggled to make 25 26" i no what i prefer ! i can always run the puppy fat off them when i get them fit in the winter
