Osteochondritis Dissecans (OCD)

descriptionOverview

OCD occurs when growing cartilage fails to properly convert to bone, creating a flap of loose cartilage inside the joint. It's a developmental disease of rapidly growing large breed puppies, typically appearing at 4-10 months of age. The shoulder is most commonly affected, followed by elbow, hock, and knee. Nutrition during growth — particularly calcium, phosphorus, and calorie levels — plays a critical role in prevention.

• warningLameness that worsens after exercise
• warningStiffness after rest
• warningSwelling around the affected joint
• warningDecreased range of motion
• warningPain when the joint is flexed or extended

restaurantHow Nutrition Helps

Prevention starts with proper nutrition during the growth phase. Overfeeding large breed puppies accelerates growth beyond what the skeleton can support, increasing OCD risk. Controlled-calorie, large-breed puppy formulas with balanced calcium and phosphorus prevent excessive growth rates. Never supplement calcium in large breed puppies — excess is a direct risk factor.

Controlled, low-impact exercise during growth. Avoid repetitive high-impact activities (jumping, hard running on pavement) for large breed puppies. Swimming builds muscle without joint stress.
