Defining and Understanding Cerebellar Hypoplasia (CH) in Dogs

What Is It?

Cerebellar Hypoplasia (CH) is a congenital neurological condition where the cerebellum, the part of the brain responsible for balance and coordination, does not fully develop. Dogs with CH are born with this condition and typically show signs from puppyhood. While CH is non-progressive and non-painful, affected dogs may have lifelong movement difficulties.

Who Gets It?

  • Puppies born with underdeveloped cerebellums, often due to viral infections or genetic factors during pregnancy.
  • Most commonly recognized in certain breeds like Chow Chows, Bull Terriers, and Wire Fox Terriers, though any breed can be affected.
  • Signs are present early in life and do not worsen over time.

Early Signs Owners May Notice

  • Uncoordinated, jerky movements when walking or running.
  • Wide-based stance for balance.
  • Head tremors that worsen with excitement.
  • Difficulty with precise movements like climbing stairs or jumping.
  • “Goose-stepping” gait or exaggerated leg movements.

How It Progresses

Cerebellar Hypoplasia is non-progressive. This means signs are present from birth or puppyhood and do not worsen over time. Many dogs adapt well to their limitations and live full, happy lives with the right support.

How Is It Diagnosed?

A veterinarian will evaluate neurologic function and rule out other causes of ataxia (incoordination). Advanced imaging may be recommended to confirm the underdevelopment of the cerebellum. Since signs are present from puppyhood and remain stable, diagnosis is often based on history and clinical findings.

The Importance of Specialist Referral

A veterinary neurologist may be consulted to confirm the diagnosis and rule out other progressive neurological conditions. Although there is no cure, guidance from a specialist and a Certified Canine Rehabilitation Practitioner (CCRP) can help maximize mobility and quality of life.

Is There a Cure?

There is no cure for CH. However, dogs with this condition can live long, comfortable lives with supportive care. Rehabilitation, safe home environments, and owner patience are key to successful management.

Benefits of Physical Rehabilitation

  • Balance support: Exercises help dogs build strength and adapt to unsteady movement.
  • Confidence building: Safe practice improves independence in daily life.
  • Owner education: Families learn safe handling and mobility strategies.

How to Help Your Dog

  • Veterinary guidance first: Confirm diagnosis and rule out progressive conditions.
  • Rehabilitation with a CCRP: Exercises tailored for balance and coordination.
  • Home safety adjustments: Use rugs, block stairs, and avoid slippery floors.
  • Harness support: Assists in guiding and stabilizing dogs during walks.
  • Patience and compassion: Dogs with CH need time to adapt and thrive.

Owner Do & Don’t List

Do Don’t
Work with your veterinarian to confirm CH diagnosis Assume clumsiness is “just a puppy phase”
Provide rugs, traction, and safe spaces Allow free access to stairs or slippery floors
Use supportive harnesses during walks Use collars that put pressure on the neck
Encourage gentle play and safe exercise Force challenging activities or jumping
Be patient and compassionate with your dog’s abilities Expect perfect coordination or precision

Prognosis

Prognosis for Cerebellar Hypoplasia is generally good. Since the condition is non-progressive and not painful, affected dogs can live normal lifespans. With rehabilitation, home adjustments, and owner patience, most dogs adapt well and enjoy active, fulfilling lives.
