If you notice your dog repeatedly pressing their heads against the wall, floor or other object for no apparent reason, your pet could have a dangerous medical condition.
The behavior is called “head pressing”, and it is characterized by the compulsive act of pressing the head against something solid for extended periods of time.
The causes of head pressing behavior can be varied, but may include:
- prosencephalon disease (in which the forebrain and thalamus parts of the brain are damaged)
- tumors (eg brain or skull)
- liver shunt
- toxic poisoning (e.g. lead poisoning)
- metabolic disorder, such as hyper or hyponatremia (too much, or too little sodium in the body’s blood plasma)
- encephalitis (inflammation of the brain and spinal cord. Many things can cause encephalitis. Infectious causes include bacteria, viruses, parasites, fungi and tick-transmitted disease).
- hepatic encephalopathy (metabolic disorder as result of liver disease)
- infection of the nervous system (rabies, parasites, bacterial, viral or fungal infection)
- head trauma
Head pressing should not be confused with a “headbutting”, where a dog or cat affectionately rubs against a person or other animal.
Head pressing can be just one symptom among other behaviors and symptoms of neurological or metabolic distress. Other behaviors and symptoms can include:
- constant pacing
- walking in circles
- face rubbing (pushing head into ground)
- damaged reflexes
- visual problems
- getting stuck in corners
- staring at walls
By recognizing head pressing and other neurologically-related symptoms in your dog or cat, you could potentially save their lives!
