Tendinitis is an inflammation of the tendons that causes lameness in dogs. The most common tendons affected are the biceps tendon (front leg) and the supraspinatus tendon (shoulder). It can be difficult to diagnose, but there are several treatment options.
Medium to large breed dogs, especially those who are very active (i.e., agility dogs, racing dogs and working dogs) are at highest risk for tendinitis.
Tendinitis can be acute (caused by an injury) or chronic (caused by repeated, high impact activity, especially running and jumping).
Most dogs with tendinitis will present with front leg lameness. It can be constant or intermittant. The leg will be painful and the dog will have limited range of motion. Signs will worsen after exercise.
Diagnosis by radiography can be difficult because tendinitis is a soft tissue injury. Other diagnostic tests like ultrasound, arthroscopy and MRI can be more useful.
Treatment for tendinitis might depend on the severity. Medical management including rest for several weeks, cold and heat therapy and anti-inflammatory drugs may be enough for a minor case. Some therapies used for cases that don't respond well to simple medical management include laser therapy, ultrasound, cross fibre massage, magnetic therapy and acupuncture.
