This is a link to a study on Labradors to evaluate the effects of diet restriction on development of radiographic evidence of hip joint osteoarthritis (caused by Canine Hip Dysplasia CHD) in dogs.
Spoiler alert! - "Dogs allowed to eat as much as they wanted showed evidence of hip dysplasia at younger ages than dogs fed less, and the difference between the groups got worse as they got older. By 6 years of age, 50% of dogs in the unlimited food group had evidence of osteoarthritis, compared with only 10% of dogs in the restricted food group. More than 50% of the dogs in the restricted food group still had radiographically normal hips at 12 years old; in the other group, 90% were arthritic. Dogs fed 25% less food than their pair in the control group weighed about 25% less throughout their lives. Heavier dogs had worse hips."
