When your dog or cat starts limping, it’s often their only way of telling you something is wrong. While some cases are mild and resolve with rest, others signal more serious conditions that require medical evaluation.

At Stanton Pet Hospital, we help pet owners in Stanton, California understand the causes of limping, the diagnostic tools we use, and the best options for treatment and home care. Here’s what you need to know if your pet is limping.

Common Causes of Limping in Dogs and Cats

Limping or lameness is one of the most frequent reasons pet owners seek veterinary care. It can come on suddenly or develop gradually, and the underlying cause can range from a minor strain to a more serious orthopedic or systemic condition. Here’s a breakdown of the most common reasons your dog or cat might be limping:

Trauma and Injury

The most immediate and recognizable cause of limping is physical trauma. Pets are naturally curious and active, which means accidents can happen—whether during a backyard zoomie session, a tumble off the couch, or a run-in with another animal.

Common traumatic injuries include:

  • Sprains and Strains: Overstretching of ligaments or muscles can lead to mild to moderate lameness. You might notice your pet limping after vigorous play, jumping, or slipping on slick surfaces.

  • Muscle Tears: Partial or complete tears in muscles (especially in the hind limbs) can cause acute, painful limping. Pets may yelp, resist touch, or avoid putting weight on the affected limb.

  • Fractures: Broken bones, whether small hairline cracks or complete breaks, typically cause sudden, non-weight-bearing lameness. A pet with a fracture may refuse to walk, vocalize in pain, or hold the limb at an unusual angle.

  • Bite Wounds or Lacerations: Outdoor cats and dogs in multi-pet households are especially prone to bite wounds, which can become infected quickly and lead to swelling, abscesses, or limping from localized pain.

When to See a Vet:
 Any sudden or severe limp—especially if accompanied by swelling, bleeding, or visible trauma—should be evaluated by a veterinarian as soon as possible. Delaying care can worsen injuries and increase the risk of complications like infection or improper healing.

Joint Diseases: Arthritis, Hip Dysplasia, and Patellar Luxation

Chronic or intermittent limping is often related to underlying joint disease, especially in middle-aged and senior pets. Some of these conditions are degenerative, while others are congenital and may appear earlier in life.

Osteoarthritis (Degenerative Joint Disease)

This progressive condition affects dogs and cats alike, especially:

  • Large-breed dogs like Labradors and German Shepherds
  • Overweight pets, where added joint stress accelerates wear
  • Senior cats, where subtle signs like stiffness, reduced jumping, or limping can be easily overlooked. Learn more at: Arthritis and DJD in Cats

Arthritis causes inflammation, stiffness, and joint pain, often resulting in a slow onset limp that worsens after rest or in cold weather. Keep learning more at Mobility Matters: Managing Arthritis – AAHA.

Hip Dysplasia

A genetic condition where the hip joint forms improperly, leading to instability and eventual arthritis. Common signs include:

  • Bunny hopping when running
  • Reluctance to climb stairs or jump
  • Limping after exercise

Hip dysplasia is most common in large-breed dogs like Golden Retrievers, German Shepherds, and Rottweilers, though it can also affect cats.

Patellar Luxation

Often seen in small or toy-breed dogs (like Pomeranians, Chihuahuas, and Yorkies), this condition occurs when the kneecap (patella) slips out of place. It can cause:

  • Sudden skipping or hopping during walks
  • Intermittent lameness that resolves when the patella returns to position
  • Chronic discomfort if left untreated

While some mild cases may not require intervention, moderate to severe luxations can lead to arthritis and mobility issues over time. Read more: Patellar Luxation in Dogs – Cornell Vet

Ligament Injuries and Lameness

The cranial cruciate ligament (CCL)—equivalent to the ACL in humans—is a common injury site in dogs. Tears can cause sudden or progressive limping and may require surgery like TPLO (Tibial Plateau Leveling Osteotomy) to restore mobility.

Foreign Bodies: Foxtails and Thorns

Foxtails are dangerous grass awns that can burrow into a dog’s paw or leg, causing pain, swelling, and infection. These are especially common in California.

Nail Injuries

Torn, cracked, or broken nails can be intensely painful and may become infected if left untreated.

Bone Tumors and Cancer

In rare cases, chronic or unexplained limping—especially in large breed dogs—can be a sign of osteosarcoma, an aggressive bone cancer.

How We Diagnose the Cause of Limping

1. Physical Examination

Our veterinarians start with a hands-on orthopedic exam, evaluating range of motion, swelling, and gait. We assess whether your pet is bearing weight and identify the affected limb or joint.

2. Diagnostic Imaging

Advanced imaging is often needed to confirm the diagnosis:

  • X-rays – Best for visualizing fractures, arthritis, and joint alignment
  • Ultrasound – Ideal for soft tissue injuries and joint effusion
  • MRI or CT scans – Recommended for complex injuries or cancer assessment

Treatment Options at Stanton Pet Hospital

Depending on the diagnosis, we may recommend:

  • Rest and restricted activity
  • Pain management with NSAIDs or supplements
  • Surgical repair for torn ligaments or dysplasia
  • Physical therapy to restore strength and mobility
  • Weight loss and joint support for arthritis cases
  • Antibiotics for infection, if present

Caring for a Limping Pet at Home

  • Limit activity until the cause is diagnosed
  • Avoid stairs or slippery surfaces
  • Use orthopedic bedding
  • Apply warm or cold compresses as advised
  • Monitor closely and keep a log of your pet’s symptoms

When Should You Call the Vet?

Contact your veterinarian if:

  • Limping persists longer than 24–48 hours
  • Your pet refuses to bear weight
  • There’s visible swelling, bleeding, or pain
  • Limping follows an injury or trauma
  • You notice behavioral changes such as lethargy, hiding, or loss of appetite

FAQs About Limping in Pets

Q: Can a limping pet heal on its own?

Q: Should I give my pet human pain medication?
 Never administer over-the-counter pain meds without veterinary approval. Some are toxic to pets.
