If your Pomeranian has started skipping a step mid-walk, holding a back leg up for a moment, or doing that strange little kick to snap things back into place, you’re probably dealing with a luxating patella. It’s one of the most common orthopaedic conditions in small breeds, and Pomeranians are firmly on the list. The good news is that with the right information, most owners can manage it confidently — and many dogs live full, happy lives with proper care.
What Sash Taught Me About This Condition
- A luxating patella ranges from a minor inconvenience to a surgical issue — grading matters enormously for how you respond.
- Spotting it early and working with your vet gives you far more options before joint damage sets in.
- Daily management — weight, exercise, flooring — makes a measurable difference even without surgery.
What Is a Luxating Patella in Pomeranians?
The patella is your dog’s kneecap. In a healthy knee, it sits neatly in a groove at the end of the femur (thigh bone) and glides smoothly as the leg flexes and extends. A luxating patella simply means the kneecap slips out of that groove — “luxate” comes from the Latin for dislocate. In Pomeranians, the patella almost always slips inward, toward the body. This is called a medial luxating patella, and it’s the direction most common in small and toy breeds.
The condition is largely genetic in Pomeranians, meaning dogs can be born with a shallow femoral groove, poor limb alignment, or a tibial crest (the bony bump below the knee) that sits too far to one side. Physical trauma can occasionally cause it too, but inherited conformation is the overwhelmingly common cause in this breed.
Recognising the Signs
When Sash was about three years old, I noticed her occasionally lifting her back right leg for a few steps during our morning walks, then carrying on as if nothing had happened. I initially put it down to something she’d stepped on. But when it happened several mornings in a row, I knew something was up. My vet confirmed a Grade 2 luxating patella at our next appointment.
Here are the signs to watch for:
- Intermittent skipping or hopping on a back leg
- A sudden leg lift mid-walk that resolves on its own
- A small kick or flick of the leg (the dog is literally popping the kneecap back into place)
- Reluctance to jump up or down from furniture
- Stiffness after rest, especially in cold weather
- In more severe cases, a crouched or bow-legged stance at the rear
Some dogs show no visible signs at all in the early grades — it’s picked up during a routine vet examination when the vet manually slides the patella out of position. Don’t assume no limp means no problem.
The Four Grades Explained
Vets use a four-grade scale to classify the severity of a luxating patella. Understanding where your dog sits on this scale is crucial because treatment decisions are built around it.
| Grade | What It Means | Typical Signs | Treatment Usually Needed |
|---|---|---|---|
| Grade 1 | Patella can be manually pushed out of the groove but returns immediately on its own | Often none, or very occasional skipping | Monitoring, weight and exercise management |
| Grade 2 | Patella luxates on its own during movement but pops back into place spontaneously or with gentle manipulation | Intermittent skipping, occasional leg lift | Conservative management; surgery considered if frequent or progressing |
| Grade 3 | Patella stays out of the groove most of the time but can be manually repositioned | Persistent lameness, abnormal stance | Surgery usually recommended |
| Grade 4 | Patella is permanently luxated and cannot be repositioned manually | Significant lameness, crouching gait, pain | Surgery typically required |
Sash was a Grade 2, which meant we had choices. We opted for conservative management first, with surgery kept as an option if things progressed. So far — touch wood — she’s remained stable.
Conservative Management: What Actually Helps
For Grade 1 and many Grade 2 cases, surgery isn’t automatically the first step. There’s a lot you can do as an owner to slow progression and keep your dog comfortable. These aren’t minor tweaks — done consistently, they make a genuine difference.
Weight Control
Every extra gram on a small dog like a Pomeranian puts disproportionate load on already compromised joints. The American Kennel Club notes that maintaining a healthy weight is one of the most impactful things an owner can do for a dog with joint issues. For Poms, that typically means keeping weight between 1.8 and 3.5 kg depending on the dog’s frame. Your vet can give you a precise target. I switched Sash to a measured feeding schedule rather than free-feeding, and it helped enormously with weight consistency.
Controlled Exercise
This one surprises people. You don’t stop exercising a dog with a luxating patella — you manage how they exercise. Muscle strength around the knee actually provides stability and helps hold the patella in position. Short, regular, low-impact walks on flat ground are ideal. Avoid repetitive jumping, rough play on slippery surfaces, and steep stairs where possible. Swimming is excellent if your Pom tolerates it.
Flooring and Home Environment
Slippery floors are a hidden enemy. Hard floors cause dogs to compensate in their gait, which stresses the joint further. Non-slip rugs, yoga mats in key areas, and toe grips (small rubber grips that fit over your dog’s nails) can reduce slipping. I put runners down on the hallway and kitchen floor after Sash’s diagnosis, and she moves with noticeably more confidence.
Joint Supplements
Glucosamine and chondroitin supplements are widely used for joint support in dogs, and there’s reasonable evidence for their role in maintaining cartilage health. Omega-3 fatty acids (fish oil) have anti-inflammatory properties that can help with joint comfort. Always check dosage with your vet before starting any supplement — the right amount for a 2 kg Pomeranian is very different from the packaging on a product aimed at larger breeds. You can find more guidance on managing your Pom’s joint health on the Pomeranian health hub.
When Surgery Is the Right Answer
Surgery becomes necessary when the luxation is frequent enough to cause ongoing pain or lameness, when the grade progresses (particularly to Grade 3 or 4), or when cartilage damage is accumulating and creating a secondary problem like osteoarthritis. If your dog is young and the condition is caught at a higher grade, early surgical intervention can actually prevent long-term joint damage — so waiting isn’t always the safer option.
Types of Surgical Correction
There are several techniques a board-certified veterinary orthopaedic surgeon might use, often in combination:
- Trochleoplasty: Deepening the groove in the femur so the patella has more to sit in
- Tibial crest transposition: Repositioning the bony attachment point to realign the pulling forces on the kneecap
- Soft tissue reconstruction: Tightening or releasing the tissues around the joint to improve patella positioning
Recovery typically involves strict rest for several weeks, physiotherapy exercises, and gradual return to normal activity. Success rates for Grade 2 and 3 surgery are high when performed by an experienced specialist. Ask your vet for a referral to a veterinary orthopaedic specialist rather than having a general practice vet perform complex joint surgery if it can be avoided.
Long-Term Outlook
A Pomeranian with a luxating patella can absolutely live a full, active, comfortable life. Grade 1 and 2 cases managed conservatively often remain stable for years. Surgically corrected cases generally do very well, with most dogs returning to normal activity. The key risk over time is secondary osteoarthritis developing in the joint from repeated cartilage stress — which is exactly why proactive management matters so much from the start.

Frequently Asked Questions
How common is luxating patella in Pomeranians?
Luxating patella is one of the most frequently diagnosed orthopaedic conditions in toy and small breeds, and Pomeranians are considered a predisposed breed. Studies suggest it affects a significant proportion of small-breed dogs, with many cases going undiagnosed because dogs compensate well in the early grades. Regular vet check-ups that include a knee assessment are the best way to catch it early.
Can a Pomeranian with a luxating patella live a normal life?
Yes, absolutely. Many Pomeranians with Grade 1 or Grade 2 luxating patella live long, comfortable lives with appropriate weight management, controlled exercise, and monitoring. Higher grades typically require surgical correction, after which the prognosis is generally very good. The key is working closely with your vet rather than ignoring the condition and hoping it resolves on its own.
At what age does luxating patella usually appear in Pomeranians?
Because the condition is largely congenital in Pomeranians, it’s often present from birth but may not become clinically obvious until the dog is between one and five years old as activity levels and body weight increase the demand on the joint. Some dogs are diagnosed during puppy wellness exams; others aren’t picked up until mid-life. There’s no single typical age — which is why routine vet exams matter throughout your dog’s life.
Is luxating patella painful for Pomeranians?
In Grade 1 and mild Grade 2 cases, many dogs show no obvious signs of pain — the kneecap slips and returns so quickly that discomfort is minimal. As grades increase and luxation becomes more frequent or permanent, pain and discomfort increase significantly. Secondary arthritis from repeated cartilage damage is often what causes chronic pain in older dogs with long-standing, unmanaged luxating patellas.
Should I avoid buying a Pomeranian puppy if the parents have luxating patella?
This is worth taking seriously. Because the condition has a strong hereditary component, responsible breeders screen breeding dogs and avoid pairing dogs with known patella problems. If a breeder can’t or won’t provide health testing information on the parents, that’s a red flag. Asking specifically about patella grading in the parent dogs is a perfectly reasonable question — any reputable breeder will expect it.
