Signs and Treatment for Tendon Injuries in Dogs

Tendon injuries in dogs can range from mild strain to complete rupture, and they often show up as limping, swelling, or reluctance to move. If your dog hurts their tendon, you may notice subtle changes at first, followed by more obvious discomfort as the injury progresses. Early recognition and prompt veterinary care help protect long-term mobility and reduce the risk of complications.

How Do Dogs Hurt Their Tendons?

Tendons connect muscles to bones, allowing smooth, controlled movement. Because they handle repeated stress, they can become injured through both sudden trauma and gradual wear over time. Many dog tendon injury cases develop during normal activities rather than dramatic accidents.

Dogs often experience tendon injuries in the following situations:

• Sudden bursts of activity, such as sprinting or jumping
• Slipping on hard or slick surfaces
• Repetitive strain from high-impact exercise
• Direct trauma from falls or collisions
• Age-related weakening of connective tissues

Active dogs, working breeds, and canine athletes face a higher risk, but any dog can develop a tendon injury. Even a routine walk can lead to strain if a dog twists awkwardly or missteps.

Types of Tendon Injuries in Dogs

Tendon injuries in dogs vary widely in severity and location. Some affect small supporting tendons, while others involve major structures that play a key role in mobility.

Strains and Partial Tears

A strain occurs when the tendon fibers stretch beyond their normal limits. In partial tears, some fibers break while others remain intact. These injuries may cause intermittent limping and mild swelling, which can make them harder to recognize early.

Complete Ruptures

A complete rupture means the tendon has fully torn. Dogs with this type of dog tendon injury often cannot bear weight on the affected limb. The injury typically requires more advanced intervention to restore function.

Commonly Affected Tendons

Certain tendons experience more stress than others, making them more vulnerable to injury:

• Achilles tendon (hind leg support and propulsion)
• Biceps tendon (front limb stability)
• Digital flexor tendons (paw and toe movement)

Each location presents slightly different symptoms, but all require careful evaluation to determine severity.

Signs Your Dog May Have a Tendon Injury

The signs of tendon injuries in dogs can vary depending on the type and severity of the damage. Some symptoms appear suddenly, while others develop gradually. You may notice:

• Limping or favoring one leg
• Swelling or heat near a joint
• Reluctance to run, jump, or climb stairs
• A dropped hock or abnormal limb position
• Pain when the area is touched
• Decreased activity or changes in gait

In some cases, a dog hurts its tendon and continues to walk, which can delay diagnosis. Subtle shifts in movement, such as shorter strides or hesitation, often provide the earliest clues.

How Veterinarians Diagnose Tendon Injuries

A thorough evaluation helps determine the extent of a dog tendon injury and guides treatment decisions. Veterinary teams use a combination of physical examination and advanced imaging to assess the affected area and confirm the exact structure involved.

During the exam, your veterinarian will:

• Evaluate gait and weight-bearing patterns
• Palpate the tendon for swelling, gaps, or pain
• Check joint stability and range of motion

In many cases, imaging provides the clarity needed to define the injury. Ultrasound allows real-time visualization of tendon fibers and can reveal inflammation, fiber disruption, or fluid accumulation. Advanced imaging, such as MRI or CT, may be recommended for deeper structures or complex injuries that are not fully visible on initial assessment.

In select cases, sedation may be used to allow a more precise orthopedic exam, especially if pain limits a dog’s ability to relax. This approach helps ensure accuracy without causing unnecessary stress.

Accurate diagnosis ensures that the treatment plan aligns with the specific injury rather than relying on general assumptions.

How Are Tendon Injuries in Dogs Treated?

Treatment for tendon injuries in dogs depends on the severity, location, and overall health of the patient. Veterinary teams focus on stabilizing the injury, reducing discomfort, and supporting proper healing while minimizing the risk of re-injury.

Conservative Management

Milder injuries, such as strains or small partial tears, may respond to controlled management. This approach focuses on protecting the tendon while it heals and preventing additional strain during recovery.

Conservative treatment may include:

• Strict activity restriction to limit stress on the tendon
• External support, such as splints or braces, to maintain proper positioning
• Rehabilitation therapy to restore strength and flexibility

Progress is typically monitored through follow-up exams and, in some cases, repeat imaging to confirm healing.

Surgical Intervention

More severe injuries, including complete ruptures, often require surgical repair. The goal of surgery is to reconnect or stabilize the tendon so it can heal in the correct position and regain function.

Surgical planning depends on the specific tendon involved, the extent of the damage, and how long the injury has been present. Early intervention often leads to more predictable outcomes, especially for weight-bearing tendons.

After surgery, dogs follow structured recovery plans that include restricted movement and gradual reintroduction of activity.

Rehabilitation and Recovery

Rehabilitation plays an important role in long-term outcomes. Even after initial healing, tendons need time and guided therapy to regain strength and flexibility.

Rehabilitation plans may involve:

• Controlled exercises to rebuild muscle support around the joint
• Range-of-motion work to maintain joint flexibility
• Gradual return to normal activity levels under veterinary guidance

Recovery timelines vary depending on the injury, but many dogs require several weeks to months for full healing. Consistency with follow-up care and rehabilitation helps improve long-term mobility and reduces the likelihood of setbacks. Close monitoring helps ensure progress stays on track.

What Happens If a Tendon Injury Goes Untreated?

When a dog hurts its tendon and does not receive timely care, the injury can worsen. Continued strain on a damaged tendon may lead to more extensive tearing, poor healing, or long-term instability within the joint.

Untreated tendon injuries in dogs may result in:

• Chronic lameness that affects daily activity
• Permanent changes in gait or posture
• Reduced range of motion in the affected limb
• Increased risk of secondary injuries in surrounding structures

Over time, compensating for a painful limb can place added stress on other joints and muscles. This compensation may lead to additional orthopedic concerns that extend beyond the original injury. Early intervention helps reduce these risks and supports better long-term mobility.

When to Seek Veterinary Care

Some signs indicate that a dog tendon injury requires prompt attention. While mild limping may seem temporary, it can signal an underlying issue that needs evaluation.

You should contact your veterinarian if you notice:

• Limping that lasts more than 24–48 hours
• Sudden inability to bear weight
• Visible swelling or deformity
• Persistent pain or sensitivity

Timely assessment allows your veterinary team to identify the issue early and begin appropriate care.
