Proprioceptive Deficits in Dogs

By: Dr. Bari Spielman

Section: Overview

Proprioceptive deficits are abnormal body positions or movements due to a lack of normal perception. Loss of proprioception causes abnormal placement reactions in the limbs (legs), abnormal limb position at rest (legs crossed or paws turned under), and abnormal wearing of the toes.

Loss of proprioception is a nonspecific indication of neurologic disease. Proprioceptive deficits may have little to no impact on the affected individual; however, its presence may represent severe or life-threatening illness, and therefore, should not be ignored and should be addressed if it persists or worsens.

General Causes

Cerebral (brain) diseases

Disorders of the brain-stem, which is the stalk-like structure of the base of the brain that attaches to the spinal cord

Disorders of the spinal-cord

Disorders of the peripheral nerves outside of the brain and spinal cord

What to Watch For

Abnormal placement reaction of the limbs in which your pet may act as though he does not know where his feet are

Abnormal limb posture at rest (limb crossed over, turned under)

Abnormal wearing of the toes

Partial loss of movement of a limb/limbs)

Paralysis (complete loss of movement of a limb/limbs)

Urinary incontinence (inability to hold urine/leaking urine)

Ataxia (incoordination)

Weakness

Seizures

Abnormal levels of consciousness

Diagnosis

Complete blood count (CBC)

Biochemical profile

Urinalysis

Thoracic (chest) and abdominal radiographs (X-rays)

Myelogram (radiographs of the spinal cord after the injection of dye)

Cerebrospinal fluid analysis (CSF tap)

Computed tomography (CT scan)

Magnetic resonance imaging (MRI)

Treatment

Depending on the specific case or patient it may be difficult or even impossible to treat proprioceptive deficits symptomatically. If appropriate, there are several things your veterinarian might prescribe or recommend to treat your pet's symptoms.

Strict cage rest

Corticosteroids

Antibiotic therapy

Home Care

Administer any prescribed medication as directed by your veterinarian. Observe your pet's general activity and appetite, and watch closely for the worsening of signs, bringing them to the attention of your veterinarian.
