Head Pressing in Dogs

Pressing the Head Against Objects in Dogs

Head pressing in dogs is a behavior marked by the repetitive action of pressing the head against surfaces like walls or objects without any evident cause. Typically, it signals underlying damage to the nervous system, which can stem from various factors such as prosencephalon disease, affecting the forebrain and thalamus, or certain forms of toxic poisoning. This behavior is not specific to any particular breed or age group of dogs.

Symptoms and Types

Head pressing serves as a single indicator of prosencephalon disease, a condition impacting the forebrain and thalamus regions of the brain. Additional symptoms linked to this condition encompass compulsive pacing and circling, alterations in learned behaviors, seizures, impaired reflexes, and visual impairments. Certain symptoms may culminate in lesions, such as foot sores stemming from compulsive pacing, or facial and head injuries resulting from prolonged periods of pressing the head against surfaces.

Causes

Various factors may prompt a dog to exhibit a compulsion to press its head against objects, contingent upon the primary cause underlying this symptom. Potential triggers encompass metabolic disorders like hyper or hyponatremia (excessive or insufficient sodium levels in the bloodstream), primary or secondary tumors (differentiating between brain tumors and those elsewhere in the body), and nervous system infections like rabies or fungal infections. Head trauma, such as that incurred from vehicular accidents, or exposure to toxins like lead, also rank among the potential causes.

Diagnosis

In diagnosing cases of head pressing, a key diagnostic step involves a fundic examination of the retina and other structures at the back of the eye. This examination helps identify potential infectious or inflammatory diseases and any abnormalities within the brain. Additionally, tests typically include blood pressure measurements to assess for hypertension, as well as computed tomography (CT) or magnetic resonance imaging (MRI) scans of the brain. Your veterinarian may also conduct a urine analysis to detect any metabolic system issues and assess blood lead concentration levels to identify potential toxins in the system.

Providing a comprehensive history of your dog’s health, the onset of symptoms, and any preceding incidents is crucial during the diagnostic process.

Treatment

Treatment protocols hinge on the observed symptoms and the diagnosis determined by your veterinarian. Hospitalization and prompt treatment are necessary for severe clinical manifestations. Each underlying cause necessitates tailored treatment, and no medications or therapies should be initiated until a definitive diagnosis is established.

Living and Management

Different diseases necessitate diverse approaches to follow-up care; nevertheless, regular neurological evaluations to track progress typically constitute the primary requirement.
