Can brachial plexus avulsion recover on its own?

Mild nerve stretching or compression may partially recover on its own, but severe avulsions typically require long-term monitoring or specialist evaluation. Your vet will recommend imaging and functional follow-up based on their assessment.

What tests are typically done at the clinic?

Common tests include a neurological and musculoskeletal physical exam, X-rays, and — if nerve damage is suspected — an MRI or CT scan, along with blood biochemistry and urinalysis to rule out other conditions.

How can I help monitor the condition at home?

Record when symptoms appeared, take front- and side-view videos of your pet's movement and gait, log daily changes in appetite and elimination, and save the footage for your vet to review.

Does my pet need a referral to a neurology specialist?

If imaging or neurological testing reveals significant nerve damage, or symptoms are not improving, a referral to a hospital with neurology expertise is recommended for further assessment and discussion of treatment options.

How much do the tests and treatment usually cost?

Costs vary by clinic and region — ask your vet for an estimate before proceeding.

When to See a Vet

Seek immediate emergency care

•Sudden complete loss of voluntary movement in a forelimb
•Persistent severe pain that cannot be soothed or relieved
•Obvious and continuous difficulty swallowing or breathing

Schedule a clinic visit soon (within 24–72 hours)

•Noticeable lameness but still able to walk briefly on their own
•Clearly avoids contact or cries out when the affected limb is touched
•Reduced activity level but still eating and responsive

01What Symptoms Indicate a Problem?

Brachial plexus avulsion commonly presents as loss of forelimb function or severe pain on one side — early recognition helps guide timely examination and monitoring.

Obvious weakness or inability to bear weight on one forelimb
Paralysis or greatly reduced range of motion in the affected forelimb
Flinching, crying out, or visible pain when the affected limb is touched
Muscle atrophy or visible asymmetry around the affected shoulder and neck
Marked decrease in ability to grip, lift, or extend the limb

Seek emergency care immediately if you notice the following symptoms:

⚠️ Sudden and complete loss of voluntary movement in the forelimb
⚠️ Persistent severe pain that cannot be calmed or managed
⚠️ Obvious and ongoing difficulty swallowing or breathing

02How Can You Assess the Situation at Home? Key Observations and When to Go to the Emergency Clinic

Monitoring and recording symptoms and daily changes at home helps your vet quickly prioritize the appropriate care.

Note when symptoms first appeared and how they have changed over time
Record front- and side-view videos of forelimb movement and gait
Track appetite, water intake, and body weight daily
Observe whether urination and defecation are normal and note any changes in frequency
Record any persistent vocalization, reluctance to be touched, or behavioral changes
Keep video and written records to assist specialist evaluation

03How Will the Vet Make a Diagnosis? Common Diagnostic Tests

At the clinic, the vet will focus on neurological and imaging examinations, alongside laboratory tests to assess overall health and rule out other causes.

Neurological and musculoskeletal physical exam

assessing sensation, reflexes, and muscle strength

X-ray or CT scan

evaluating bones, joints, and possible traumatic fractures

MRI

assessing nerve roots, soft tissues, and spinal cord involvement

Blood and biochemistry panel

checking for infection or metabolic issues

Urinalysis

ruling out metabolic or infectious complications

04How Is This Condition Treated and Managed? Medications, Lifestyle Adjustments & Home Care Guide

Treatment ranges from conservative management to surgery depending on severity — pain control, activity restriction, and rehabilitation are the core ongoing priorities.

Assess suitability for conservative management or surgical reconstruction based on the extent of injury
Manage pain and reduce inflammation as directed by your vet
Avoid pulling or straining the affected limb at home and restrict jumping and vigorous activity
Arrange physiotherapy or rehabilitation as needed to promote functional recovery
Schedule regular follow-up imaging and neurological function assessments

05What Should You Prepare Before the Vet Visit? Key Information to Help Your Vet

Note when symptoms started, daily changes, and any possible triggers

Bring video files of forelimb movement and gait (smartphone video is fine)

Prepare a log of recent changes in appetite, bowel and bladder habits, and body weight

List any current medications, supplements, and dosages

Bring any prior relevant test results or imaging reports if available

Consider calling ahead to book an appointment and ask what to bring
