If your Havanese is limping on his back leg, the most likely cause is patellar luxation, a common condition in small breeds where the kneecap slips out of place. Other possibilities include hip dysplasia, cruciate ligament injury, or a simple sprain. This article will help you understand the possible reasons and what steps to take.
Recognizing the Signs: What to Look For
When your Havanese limps, pay close attention to how he holds his leg. Is he bearing weight intermittently, or does he refuse to use it at all? In patellar luxation, dogs often skip or hop for a few steps then resume normal walking. You might hear a clicking sound when the kneecap moves. Hip dysplasia tends to cause stiffness, especially after rest, and a bunny-hopping gait when running. A cruciate ligament injury usually results in sudden, severe lameness with minimal weight bearing. Also check for swelling, warmth, or any obvious wounds. Note when the limping started – was it sudden after an activity, or gradual?
Common Causes of Back Leg Limping in Havanese
Patellar Luxation: This is the top suspect, especially for Havanese. It ranges from mild (grade I) where the kneecap pops out occasionally to severe (grade IV) where it stays out. Treatment varies from physical therapy to surgery for higher grades.
Hip Dysplasia: Though more common in larger dogs, Havanese can have it. It develops over time as the hip joint doesn’t fit properly, leading to arthritis and pain. X-rays diagnose it.
Cranial Cruciate Ligament (CCL) Tear: Similar to ACL tears in people, this causes instability in the knee. It’s often sudden but can be gradual. Surgery is often recommended for active dogs.
Soft Tissue Injuries: Sprains, strains, or muscle injuries from jumping or rough play. These usually heal with rest.
Other Possibilities: fractures, dislocations, bone cancer (rare), or inflammatory conditions. A vet can rule these out.
When to See a Vet and How to Help at Home
Consult a veterinarian if the limp lasts more than 24 hours, if your dog is in obvious pain, or if he won’t bear weight at all. For mild, intermittent limping, rest your Havanese for a few days – limit walks to short, leash-only potty breaks, no running or jumping. Apply a cold pack (wrapped in a towel) for 10-15 minutes if there’s swelling. Do not give human pain medications like ibuprofen or acetaminophen – they are toxic to dogs. Your vet may recommend joint supplements, anti-inflammatories, or a brace. For patellar luxation, sometimes weight management and physical therapy help. In severe cases, surgery may be needed.
Preventing Future Limps
Keep your Havanese at a healthy weight – extra pounds strain joints. Provide joint supplements with glucosamine and chondroitin, especially as he ages. Avoid high-impact activities like jumping off furniture – use ramps or steps. Regular, gentle exercise strengthens muscles that support joints. And finally, consider genetic screening for patellar luxation and hip dysplasia if you’re getting a puppy from a breeder.

Key Takeaway
If your Havanese limps on a back leg, suspect patellar luxation first; rest him, but always consult a vet if the limp persists for more than a day or is severe.
