Acute lameness in dogs can manifest through a variety of signs, most of which involve changes in gait and behavior. These signs can range from subtle shifts in weight distribution to an obvious inability to bear weight on the affected limb. Recognizing these signs early is crucial for prompt veterinary intervention and effective management of the underlying cause.
What Are the Signs of Acute Lameness in Dogs?
Obvious Signs of Lameness
- Limping: The dog favors one leg while walking or running.
- Non-Weight Bearing: The dog refuses to put any weight on the affected leg.
- Stiffness: Difficulty rising or moving, especially after rest.
Subtle Signs of Lameness
- Changes in Posture: The dog stands or sits with an unusual posture to relieve pressure on the affected limb.
- Decreased Activity Level: The dog is less willing to play, jump, or go for walks.
- Swelling or Pain: Obvious swelling, heat, or sensitivity to touch in the affected limb.
- Behavioral Changes: The dog may become irritable, withdrawn, or aggressive when the affected area is touched.
Gait Abnormalities
- Head Bob: The dog’s head bobs up when the affected leg is weight-bearing, indicating pain.
- Shortened Stride: The dog takes shorter steps with the affected leg.
- Circumduction: The dog swings the affected leg outward in a circular motion to avoid bending the joints.
Compensatory Changes
- Muscle Atrophy: Noticeable muscle loss in the affected limb due to disuse.
- Overuse of Other Limbs: Increased muscle mass in the non-affected limbs as they compensate for the injured leg.
How Is Lameness Diagnosed?
Veterinarians use a combination of physical exams and diagnostic tests to determine the cause and location of lameness.
- Physical Examination: The vet will observe the dog’s gait, palpate the limbs, and assess joint range of motion.
- Neurological Exam: To rule out nerve-related issues, especially if there are any signs of neurological problems.
- Imaging: X-rays, ultrasounds, CT scans, or MRIs may be used to visualize bones, joints, and soft tissues.
- Joint Fluid Analysis: If a joint is affected, a sample of joint fluid may be taken to check for infection or inflammation.
What Are Common Causes of Acute Lameness?
- Trauma: Fractures, dislocations, sprains, and strains are common causes of sudden lameness.
- Infection: Infections in the bone (osteomyelitis) or joints (septic arthritis) can cause acute lameness.
- Foreign Body: A thorn, splinter, or other foreign object lodged in the paw can cause sudden lameness.
- Musculoskeletal Disease: Conditions like arthritis, hip dysplasia, or elbow dysplasia can flare up and cause acute lameness.
- Neurological Issues: Nerve damage or spinal cord problems can sometimes manifest as lameness.

How Quickly Should I See a Vet for Acute Lameness?
If your dog suddenly becomes lame, it’s best to consult a vet within 24-48 hours. Immediate vet attention is needed if the dog can’t bear weight, has an open wound, or shows signs of extreme pain.
Can Acute Lameness Resolve on Its Own?
Mild strains or sprains might improve with rest, but it’s risky to assume the lameness will resolve without veterinary advice. Underlying issues like fractures or infections need prompt treatment to prevent complications.
What Can I Do at Home While Waiting for the Vet Appointment?
Restrict your dog’s activity to prevent further injury. Provide a comfortable resting place, and avoid touching the affected area unless necessary. Never administer human pain medication, as many are toxic to dogs.
How Can I Prevent Acute Lameness?
Maintain your dog’s weight to reduce joint stress. Ensure regular, moderate exercise to keep muscles strong. Inspect your dog’s paws regularly for injuries or foreign objects.
What Is the Prognosis for Acute Lameness?
The prognosis varies widely depending on the cause and severity of the lameness. With prompt and appropriate treatment, many dogs can recover fully and return to their normal activity levels.
Recognizing the signs of acute lameness in dogs and seeking timely veterinary care are essential for ensuring a positive outcome.
