A separate study that followed Labradors from 8 weeks to 2 years of age found that dogs fed 75 % of
the ad lib intake of matched littermates resulted in a significant decrease in the radiological and clinical signs of hip dysplasia (6).
When growing large - breed puppies were fed 50 % — 70 % of their littermate's
ad lib intake, adult height, length, and bone or muscle mass were not stunted; only total body fat was affected.
