The Giant Breed Growth Challenge

Great Danes are the largest common breed with an extraordinary growth rate that creates unique joint stress.

  • 📏 Growth plates open until ~24 months — 6 months longer than standard large breeds
  • ⚖️ Adult weight of 110–175 lbs on joints that were cartilage months earlier
  • 🏃 5–10 lbs/month growth rate means the skeleton is constantly under construction
  • 🦴 Predisposition to OCD, HOD, and panosteitis during the growth phase

The 5 Early Warning Signs

Monitor closely from months 4–18. Growth issues can appear suddenly.

🦮

Uneven Gait

Limping or asymmetric stride, especially after exercise.

🐇

Bunny-Hopping

Both rear legs moving together — a hip or growth plate sign.

😴

Exercise Intolerance

Lying down during walks or reluctance to play.

🦵

Joint Swelling

Visible swelling around knee, ankle, or wrist joints.

📉

Slow to Rise

Difficulty getting up after rest. Stiffness that improves with movement.

⚠️ If you notice 2 or more of these signs, your Great Dane may be experiencing growth-related joint stress.
