Causes

A dog’s brain is a delicate organ protected by the skull. The skull consists of several bones that surround and protect the brain. In a traumatic brain injury, the brain is pressed against the skull by an external force, which can lead to bleeding, swelling, or bruising. These injuries can impair the normal function of the brain.

The most common causes of traumatic brain injury in dogs include car accidents, falls from heights, or attacks by other animals. Human influences, such as abuse, can also lead to a TBI. Other causes may include sporting activities or accidents during play, where the dog collides with hard objects at high speed.

In addition to external causes, certain factors can increase the risk of TBI. These include the dog’s breed, age, and general health. Young, very active dogs are more often affected because they are more likely to get into risky situations. Smaller breeds with more fragile bone structures may be more susceptible to serious consequences of traumaA trauma refers to a physical injury or damage caused by external force.
