Have you ever noticed your dog suddenly skip a few steps during a walk, only to continue on as if nothing happened? While it may seem like an odd habit or a funny quirk, that brief "skip" could be a sign of a common orthopedic condition known as a medial luxating patella.

A medial luxating patella occurs when the kneecap (patella) slips out of its normal groove on the inside of the knee. This condition is one of the most common orthopedic issues seen in dogs, especially small and toy breeds such as Chihuahuas, Pomeranians, Yorkshire Terriers, Maltese, and Toy Poodles. However, larger breed dogs can also be affected.

What Causes a Luxating Patella?

Most dogs with a luxating patella are born with subtle differences in the alignment of their leg bones or the groove where the kneecap sits. Over time, these structural changes allow the kneecap to move in and out of place. While some dogs experience only occasional episodes, others develop more severe instability as they age.

The condition is graded from Grade I (mild) to Grade IV (severe), depending on how easily the kneecap moves out of position and whether it can return to its normal location.

Signs Your Dog May Be Showing

Some dogs with mild luxating patellas show very few signs, while others develop noticeable discomfort. Common symptoms include:

·       Skipping or hopping while walking or running

·       Briefly carrying a back leg before using it normally again

·       Bunny hopping

·       Difficulty jumping onto furniture or into the car

·       Stiffness after exercise

·       Reluctance to play or go for walks

·       Limping that comes and goes

Because many dogs continue acting normally between episodes, owners often delay having the condition evaluated. However, even intermittent luxation can lead to gradual damage within the joint.

Why Early Treatment Is So Important

Although some mild cases can be successfully managed with monitoring and regular examinations, untreated luxating patellas often worsen over time. Every time the kneecap slips out of place, it can cause additional wear on the cartilage and increase inflammation within the joint.

As the condition progresses, dogs become more likely to develop arthritis, chronic pain, and even injuries to other structures within the knee, including the cranial cruciate ligament.

Early diagnosis allows your veterinarian to monitor progression, discuss treatment options, and determine the best time for intervention if surgery becomes necessary. Addressing the problem before significant arthritis develops often leads to better long-term outcomes and improved quality of life.

How Is It Treated?

Treatment depends on the severity of the condition, your dog's age, activity level, and clinical signs.

Mild cases may simply require routine monitoring, weight management, exercise modification, and supportive care. Dogs with more advanced grades or persistent lameness often benefit from surgery to realign the kneecap and stabilize the joint.

The goal of treatment is not only to relieve discomfort but also to prevent further damage and help preserve normal joint function for years to come.

A Healthy Weight Helps Protect the Knees

One of the easiest ways to support dogs with orthopedic conditions is by maintaining a healthy body weight.

Get their pets to lose weight if they are overweight. Every extra pound places additional stress on the knees and other joints, making movement more difficult and increasing wear over time. Helping your dog maintain an ideal body condition can improve mobility, reduce discomfort, and support better long-term joint health.

Don't Wait to Have That "Funny Skip" Checked

It's easy to dismiss an occasional limp or skipped step, especially if your dog seems perfectly fine a few moments later. However, subtle signs are often your dog's way of telling you something isn't quite right.

If you've noticed your dog skipping, hopping, or favoring a back leg—even occasionally—schedule an orthopedic examination with your veterinarian. Identifying a medial luxating patella early gives us the best opportunity to protect the joint, reduce discomfort, and help your dog stay active and comfortable throughout their life.
