How to Tell If Your Dog Has a CCL Tear

A torn cranial cruciate ligament (CCL) is one of the most common orthopedic injuries in dogs—and one of the most commonly overlooked. Many pet parents don’t realize something is wrong until the condition worsens. Knowing how to recognize the signs of an injury to the knee early can make a major difference in your dog’s comfort, recovery options, and long-term joint health.

What is the CCL and Why It Matters

The cranial cruciate ligament in dogs (similar to the ACL in humans) helps stabilize the knee joint, known as the stifle. When this ligament is stretched or torn, it causes pain, inflammation, and instability—often leading to limping or even complete lameness.

Key Signs of a Possible Knee Injury

If your dog is showing any of the following symptoms, visit your veterinarian as soon as possible:

  • Limping or favoring one leg, especially after play or rest
  • Difficulty rising, jumping, or climbing stairs
  • Swelling around the knee joint
  • Stiffness, especially in the morning or after activity
  • “Toe-touching” gait—holding one paw slightly off the ground while standing
  • Audible clicking or popping in the knee

It’s important to note: symptoms can be subtle or intermittent, especially in the case of partial tears. Don’t wait for the issue to worsen.

At-Home Assessment Tips

While only a veterinarian can definitively diagnose a CCL tear, you can perform a few gentle at-home checks:

  • Watch for symmetry: Is one leg thinner than the other? Muscle atrophy may signal disuse due to pain.
  • Gently feel the joint: Swelling or heat around the knee is a warning sign. (Avoid manipulating the joint—this can worsen the injury or cause your dog discomfort.)
  • Observe your dog’s posture: A dog with a CCL tear may shift weight away from the injured leg.

Next Steps: Vet Diagnosis

Your vet may perform a physical exam involving the “drawer test” (to assess joint instability) or recommend bloodwork or imaging like X-rays. Early diagnosis allows for a more conservative approach in some cases—especially with partial tears.

Don’t Wait—Act Early
