TPLO (Tibial Plateau Leveling Osteotomy) is a surgical procedure commonly performed on dogs to address cruciate ligament injuries in their hind legs. While TPLO is an effective treatment, it's essential for dog owners to be aware of the symptoms associated with this condition. By recognizing the signs early on, pet owners can seek timely veterinary care and ensure their beloved companions receive the necessary treatment. In this article, we will explore the various symptoms of TPLO in dogs, shedding light on the key indicators that may signal the need for veterinary intervention.

Symptoms of TPLO in Dogs:

1. Lameness and Difficulty Walking: Dogs with TPLO may exhibit lameness or favor one leg over the other. They might also have difficulty walking or refuse to put weight on the affected leg.

2. Swelling and Heat: Inflammation, heat, and swelling around the knee joint can be indicative of TPLO in dogs. These symptoms may develop gradually or become more pronounced over time.

3. Stiffness and Limited Mobility: Dogs with TPLO may experience stiffness and have limited range of motion in the affected leg. They may exhibit reluctance to engage in physical activities they previously enjoyed.

4. Pain and Discomfort: Dogs in pain may display signs such as whimpering, yelping, or becoming more irritable. They might avoid being touched or exhibit signs of discomfort when the affected leg is manipulated.

5. Muscle Atrophy: Over time, TPLO can cause muscle atrophy in the affected leg, leading to a noticeable decrease in muscle mass and strength.

6. Difficulty Rising or Sitting: Dogs with TPLO may struggle to rise from a lying position or find it challenging to sit comfortably. These difficulties arise from the pain and instability caused by the ligament injury.

7. Changes in Behavior and Activity Levels: Dogs experiencing TPLO may demonstrate changes in their behavior and activity levels. They may become less interested in playtime, exercise, or even everyday activities like climbing stairs.

8. Altered Posture: TPLO can cause dogs to shift their posture to compensate for the affected leg. They may adopt a hunched or unusual stance to reduce discomfort and redistribute weight.

9. Audible Clicking Sound: Some dogs with TPLO may produce an audible clicking sound when they move their affected leg. This clicking noise may indicate joint instability or damage.

10. Decreased Appetite: Dogs in pain or discomfort may show a decreased appetite, resulting in a noticeable decline in their food consumption.

11. Limping After Rest: Dogs with TPLO may experience increased discomfort after periods of rest. They may limp or exhibit more pronounced lameness when they start moving again.

12. Abnormal Gait: Dogs with TPLO may exhibit an abnormal gait characterized by uneven steps, hopping, or a noticeable change in how they walk.


Recognizing the symptoms of TPLO in dogs is crucial for early detection and prompt intervention. By staying vigilant and observing changes in your dog's behavior, gait, and mobility, you can identify the signs of TPLO and seek veterinary assistance promptly. Remember, timely treatment plays a significant role in improving the prognosis and overall quality of life for dogs with TPLO. If you notice any of the aforementioned symptoms in your furry friend, consult your veterinarian for a thorough examination and appropriate treatment options.
