Weight-Related Conditions

A line-up of the outlines of five dogs, one of those outlines is filled in.

Canine osteoarthritis

One in five adult dogs suffers from osteoarthritis, a progressive and painful condition that reduces mobility and quality of life.1

Purina's research

Golden Retriever puppy

In a landmark study, Purina researchers monitored the health of 48 Labrador Retrievers from puppyhood throughout their lives.2 The results showed that dogs fed to maintain a lean body condition from puppyhood throughout life had significantly less osteoarthritis, in addition to having a longer lifespan.2-4

In this study, the mean age at which 50% of the dogs in each group first required long-term treatment for osteoarthritis was significantly (P < 0.01) later for the lean-fed group (13.3 years) than for the control-fed group (10.3 years).2

Severity of hip displaysia chart. In 2 groups of 24 dogs, one group being a control group and the other group being lean-fed; records of the number of dogs showing any sign of hip displaysia. Control group: mild, 7, moderate, 5, severe, 5. Control total 17 of 24 dogs. Lead-fed group: mild, 2, moderate, 4, severe, 3. Lean-fed total, 9 of 24 dogs.

By two years of age, the frequency of hip dysplasia in the lean-fed dogs was 50% less than in the control group, and the hip dysplasia was much less severe.5

At the end of the study, only 50% of the lean-fed group had radiographic signs of hip osteoarthritis compared to 83% of control-fed dogs.3

Maintaining a lean body condition also resulted in lower prevalence and severity of shoulder osteoarthritis and elbow osteoarthritis, respectively, at 8 years of age.4

Key thing to remember

  • Dogs fed to maintain a lean body condition from puppyhood throughout life had significantly less osteoarthritis, in addition to a longer lifespan.
