What are the early symptoms of degenerative myelopathy?

Early signs are mainly gait changes — such as slow, dragging hind steps, unsteadiness, or frequent slipping. Abnormal elimination control may also appear. If you notice any changes, filming a video to share with your vet is strongly recommended.

What tests will the vet use to evaluate my dog?

The vet will perform a physical and neurological examination first, then arrange X-ray, CT, or MRI as appropriate to evaluate the spine and spinal cord. Urinalysis or blood work may also be included when needed.

What home care can I provide?

You can add non-slip surfaces at home, manage your dog's weight, and support gentle passive exercises or physical therapy to help maintain function. Ask your vet or a rehabilitation therapist for specific guidance tailored to your dog.

When should I take my dog to the emergency clinic?

If your dog suddenly cannot walk at all, is unable to urinate for an extended period, or shows difficulty swallowing or breathing, go to an emergency clinic immediately. For other abnormal signs, arrange a daytime appointment as soon as possible.

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 Emergency Care Immediately

•Sudden hind limb weakness with complete inability to walk
•Prolonged inability to urinate or complete loss of urination
•Difficulty swallowing or noticeably affected breathing

Schedule a Clinic Visit Soon (within 24–72 hours)

•Unsteady gait, frequent slipping, or changes in stepping pattern
•Noticeable difficulty climbing stairs or rising from rest
•Loss of bladder or bowel control, or occasional incontinence

01What symptoms indicate something is wrong?

Degenerative myelopathy typically begins with gait abnormalities — early signs are usually hind limb lameness or altered foot placement. Over time the condition progressively affects mobility and elimination control.

Unsteady gait, frequent slipping, or changes in foot placement
Hind limb weakness with slow, dragging steps when walking
Noticeable difficulty climbing stairs or rising from rest
Abnormal bladder or bowel control, or episodes of incontinence
Seek a veterinary assessment promptly if any changes in gait are noticed

Seek emergency care immediately if you notice the following symptoms:

⚠️ Sudden complete inability to walk or stand in the hind limbs
⚠️ Prolonged inability to urinate or complete loss of bladder control
⚠️ Difficulty swallowing or noticeably laboured breathing

02How can I assess the situation at home? Key observations and emergency criteria

Observing and recording changes across five key areas at home helps the vet assess the condition and track progression quickly.

Monitor and record changes in alertness and daily activity levels
Note whether appetite and water intake have changed noticeably
Weigh your dog regularly and track short-term fluctuations
Record urination and defecation frequency, incontinence, or loss of control
Film your dog walking (side view and front view) on your phone for the vet's reference
If symptoms continue to worsen or emergency signs appear, schedule a clinic visit

03How will the vet diagnose this? Common diagnostic tests

The vet will start with a physical and neurological examination, then order imaging as needed to assess the spinal cord and vertebral column.

Physical and neurological exam

assess reflexes, muscle strength, and sensory responses

Urinalysis and bacterial culture if needed to rule out infection

X-ray

initial assessment of spinal structure and degenerative changes

CT scan

detailed evaluation of bony structures and complex lesions

MRI

the best modality for evaluating soft-tissue spinal cord lesions — referral to a specialist hospital with MRI capability is recommended

04What treatment and care come after diagnosis? Medications, diet, and home management

Treatment focuses on symptomatic support and functional maintenance. Regular monitoring of neurological function and quality of life is essential.

Use pain relief or symptomatic medications as directed by your vet, and report back on response
Dietary management and maintaining an ideal body weight to reduce spinal load
Improve the home environment with non-slip mats and mobility aids to prevent falls
Gentle rehabilitation or physical therapy to maintain muscle strength and joint mobility
Schedule regular follow-up visits to assess disease progression; imaging or specialist referral may be arranged as needed

05What should I prepare before the vet visit? Key information to help the vet diagnose quickly

Record when symptoms first appeared, how they have changed, and how quickly they are worsening

List your dog's diet, current medications, and any supplements being given

Bring elimination records and walking videos (front and side view)

Bring previous diagnostic reports or images (e.g. X-rays, CT, MRI) if available

Use a secure carrier or lead when travelling; booking an appointment in advance is recommended
