Dogs can incur brain injuries from a variety of causes, including severe hyperthermia or hypothermia and prolonged seizures. Primary brain injuries, for example, involve direct trauma to the brain, which once acquired, cannot be altered. Secondary brain injury, meanwhile, is the alteration of brain tissue that occurs after primary injury, but this form of injury can be managed, prevented, and improved with optimal supportive care and treatment.
Being that it is a vital organ, the brain requires constant supply of oxygen and nutrition. Any deficiency of oxygen or direct trauma to the brain, therefore, may result in bleeding and fluid buildup, which can cause excessive pressure on the brain. This in turn can cause complications involving the heart, eye, and several other body systems. Symptoms vary and depend on the cause and severity of the brain injury. Some of the more common symptoms include:
You will need to give a thorough history of your dog’s health to your veterinarian, including the onset and nature of the symptoms, and possible incidents that might have precipitated the unusual behaviors or complications. He or she will then perform a complete physical examination as well as a biochemistry profile, urinalysis, and complete blood count. Although the findings for these tests depend on the underlying cause of the brain injury, often the biochemistry profile may indicate abnormalities in the blood glucose level. Blood gases are also measured to confirm oxygen deficiency in the blood.
When fractures involving the skull are suspected, X-rays, CT (computed tomography) scans, and MRIs (magnetic resonance imaging) are extremely useful to evaluate the severity of the brain trauma. These diagnostic tools also help in determining the presence of bleeding, fractures, foreign bodies, tumor, and other abnormalities involving brain. The ECG (electrocardiogram), meanwhile, is used to evaluate heart functions and rhythm.
Your veterinarian may also collect cerebrospinal fluid sample to determine the level of inflammation and to confirm possible infections.
Any type of brain injury should be considered an emergency that requires immediate hospitalization for intensive care and treatment. In fact, depending on the cause of the brain injury, surgery may be required. However, often the primary goal of emergency treatment is to normalize the dogs temperature and blood pressure, provide adequate levels of oxygen and prevent hypoxia.
In order to assist with breathing, a tube will be passed into the trachea to supply oxygen. Small amounts of fluids may also be given to animals with fluid deficits in order to maintain blood pressure. To reduce brain swelling, the dog will be given medication and its head will be kept above the level of the body. In addition, the dog is turned over every two hours to avoid complications.
Yes, dogs can definitely get brain damage, and it’s something every pet parent should be aware of As someone who’s spent countless hours researching canine health issues (and worrying about my own furry friend!), I’ve learned that brain injuries in dogs can be both devastating and surprisingly common Whether from accidents, illness, or other causes, damage to your dog’s brain requires immediate attention and proper care.
What Causes Brain Damage in Dogs?
Brain injuries in dogs typically fall into two main categories: primary injuries and secondary injuries. Let me break these down for you:
Primary Brain Injuries
These happen at the moment of trauma and include:
- Vehicle accidents (sadly, one of the most common causes)
- Falls from heights (like falling off furniture or down stairs)
- Direct trauma to the head (being hit or kicked)
- Dog fights or bites that damage the skull
- Penetrating injuries from objects
My neighbor’s terrier suffered a primary brain injury after falling from their second-story balcony. The poor pup required immediate emergency care, but thankfully made a good recovery with proper treatment.
Secondary Brain Injuries
These develop following the initial trauma and can include:
- Bleeding inside the skull
- Swelling of brain tissue
- Decreased blood flow to the brain
- Oxygen deprivation
- Inflammation
Secondary injuries can sometimes be more dangerous than the primary ones because they continue to damage brain tissue over time if not addressed quickly,
Other Causes of Brain Damage
Brain damage isn’t always traumatic Dogs can experience brain injuries from
- Prolonged seizures
- Toxin exposure
- Severe hypoglycemia (low blood sugar)
- Extreme body temperature (too high or too low)
- Blood clots traveling to the brain
- Infectious diseases
- Brain tumors
- Cardiac or respiratory arrest
Signs That Your Dog Has Brain Damage
Recognizing the signs of brain damage is crucial for getting your pup help quickly. The symptoms can range from obvious to subtle, depending on which part of the brain is affected and how severe the damage is.
Common Signs of Brain Injury in Dogs:
- Changes in consciousness (confusion, disorientation)
- Abnormal walking or coordination problems (ataxia)
- Circling repeatedly, especially when excited or stressed
- Seizures
- Unequal pupil size (anisocoria)
- Abnormal eye movements or lack of response to light
- Bleeding from the nose or ears
- Visible trauma to the head
- Difficulty regulating body temperature
- Slow heart rate
- Facial weakness or loss of sensation
- Loss of spatial perception
- Behavioral changes
In severe cases, you might notice:
- Loss of consciousness
- Coma
- Brain matter in the ear canal (in traumatic cases)
We once noticed our dog was walking in circles and bumping into furniture after she’d been playing roughly with a larger dog. We didn’t see any trauma happen, but these behavioral changes were enough to warrant an immediate vet visit, which revealed a minor concussion.
Diagnosing Brain Damage in Dogs
If you suspect your dog has suffered brain damage, getting a proper diagnosis is essential. Veterinarians use several methods to assess canine brain injuries:
Clinical Assessment
The vet will check:
- Mental status and consciousness level
- Reflexes and response to stimuli
- Pupil size and responsiveness
- External signs of trauma
- Vital signs (temperature, heart rate, breathing)
Blood Tests
These might include:
- Complete blood count
- Blood glucose level (very important!)
- Electrolyte levels
- Packed cell volume (PCV) to check for blood loss
Advanced Imaging
In some cases, your vet might recommend:
- CT scan – Provides detailed images of the brain structure
- MRI – Offers even more detailed images of brain tissue
- Note: These tests require sedation, which can be risky for a dog with brain injury, so they’re only used when absolutely necessary
Emergency Treatment for Canine Brain Injuries
Brain injuries are medical emergencies that require immediate veterinary attention. Treatment typically focuses on:
Stabilization (The ABCs)
- Airway – Ensuring your dog can breathe
- Breathing – Supporting respiration if needed
- Circulation – Maintaining adequate blood flow
Controlling Brain Swelling
- Medications like mannitol may be given to reduce intracranial pressure
- Careful fluid therapy to avoid increasing brain swelling
Oxygen Therapy
- A nasal cannula or oxygen cage might be used to increase oxygen to the brain
Pain Management
- Pain relief and anti-anxiety medications
Preventing Secondary Complications
- Monitoring and treating seizures with anticonvulsants
- Regulating body temperature
- Maintaining proper blood glucose levels
Supportive Care
- Proper positioning (head should never be lower than the body)
- Eye lubrication if blinking is impaired
- Prevention of urine/stool soiling if mobility is affected
- Nutritional support, possibly through feeding tubes
I’ve seen firsthand how quickly vets work in these situations. When my friend’s Labrador was hit by a car, the emergency team immediately focused on stabilizing him and reducing brain swelling before any other injuries were addressed.
Long-Term Care & Recovery
Recovery from brain injury depends on several factors:
- Severity of the initial damage
- Time between injury and treatment
- Age and overall health of the dog
- Location and extent of brain damage
- Presence of other injuries
Recovery Timeline
It’s important to understand that:
- Improvement may be slow and gradual
- Some nervous system signs might actually worsen before improving
- Full recovery can take up to 6 months or longer
- Young dogs with minor injuries have the best prognosis
Rehabilitation May Include:
- Physical therapy
- Range of motion exercises
- Supported walking
- Swimming therapy
- Cognitive stimulation
Potential Long-Term Complications
Some dogs may experience:
- Ongoing seizures
- Permanent neurological deficits
- Visual impairments
- Movement disorders
- Behavioral changes
Prevention is Better Than Treatment
While not all brain injuries can be prevented, you can reduce the risk by:
- Keeping dogs on leash near roads
- Securing windows and balconies
- Supervising play between dogs, especially of different sizes
- Using appropriate restraints in vehicles
- Preventing falls from heights
- Keeping toxins out of reach
Cost of Treating Brain Injuries in Dogs
Treatment for canine brain injuries isn’t cheap, unfortunately. The costs can vary widely depending on:
- Severity of the injury
- Required diagnostics
- Length of hospitalization
- Specialty care needed
- Geographic location
According to some sources, the average cost ranges from $500 to $8,000, with an average around $3,500. However, complex cases requiring neurological specialists and extended care can exceed $10,000.
This is definitely one of those situations where having pet insurance can make a huge difference in your ability to provide the best care possible.
Real-Life Recovery Stories
I’ve seen some amazing recoveries from canine brain injuries. My cousin’s Border Collie fell off a 15-foot ledge while hiking and suffered a serious head trauma. After intensive care and three months of rehabilitation, he regained about 90% of his function. He still has a slight head tilt and occasional balance issues, but his quality of life is excellent.
Not all stories have happy endings, though. Some severe brain injuries result in permanent disabilities or may not be survivable despite the best veterinary care. The key factors are usually how quickly treatment was started and how severe the initial injury was.
When to Say Goodbye
One of the hardest decisions pet parents may face is determining when a brain-injured dog’s quality of life is too compromised. Some questions to consider:
- Is your dog in pain that can’t be controlled?
- Can they perform basic functions like eating and eliminating?
- Do they still show interest in their surroundings?
- Is there a reasonable chance of meaningful recovery?
Your veterinarian can help guide you through this difficult decision process with compassion and medical expertise.
Final Thoughts
Brain damage in dogs is serious business, but with prompt veterinary care, many dogs can recover partially or even fully. The key is recognizing the signs early and getting immediate help. As dog lovers, we need to be vigilant about potential hazards and responsive to behavioral changes that might indicate something is wrong with our furry friends’ neurological health.
If you suspect your dog has suffered a brain injury, don’t wait – get to a veterinarian or emergency animal hospital immediately. Minutes can make the difference between a good outcome and a tragic one.

FAQ
What happens if a dog gets a brain injury?
Brain injury in dogs results from a trauma to the head, leading to neurological dysfunction. Also known as traumatic brain injury (TBI), this is an occurrence that happens quite commonly due to incidents such as vehicular accidents or falls. Due to the complexity of the injury, immediate veterinarian care is critical in the event of a brain injury.
How do you know if a dog has brain damage?
Additional signs of brain harm in dogs may include enlarged pupils, irregular eye movements, seizures, staggering or tripping when walking, short-term blindness or deafness or permanent hearing loss and difficulty breathing.
How is a dog’s brain injury treated?
Treatment of a dog’s brain injury depends on what led to the brain injury. The initial goal of treatment is to maximize oxygen levels in the brain tissue. If the blood pressure is too low, then supporting blood pressure improves brain blood flow.
What happens if a dog has a head trauma?
A little ruff around the edges and maybe some woof brain. When a pup experiences trauma to the head, it can cause a variety of changes in behaviour. These can vary from sluggishness, disorientation and confusion to aggression, restlessness and lack of appetite.
What is the long-term outlook for a dog with a brain injury?
For a young dog with a minor primary brain injury, and secondary injury limited to fluid build-up in the brain, the long-term outlook is favorable. If the dog experiences no additional nervous system deterioration over a 48-hour period, the prognosis remains favorable.
What is Atraumatic brain injury in dogs & cats?
Traumatic brain injury is a common injury to dogs and cats and can result from motor vehicular accidents, falls from heights, bite wounds, blunt trauma, etc. Brain injury is divided into primary and secondary brain injury: Primary injury is the direct injury to the brain that occurs at the time of contact/trauma.
How do dogs act when they have brain damage?
… can cause complete or partial blindness, loss of the sense of smell, seizures, coma, stupor, pacing or circling behavior, and inability to recognize an owner
Can a dog recover from a brain injury?
Yes, dogs can recover from brain damage, with outcomes ranging from full recovery to permanent neurological deficits, depending on the severity and cause of the injury, and prompt veterinary care. Younger dogs with less severe injuries, such as traumatic brain injuries (TBI), often have a good chance of making a full recovery, while older dogs or those with pre-existing conditions may have a less certain prognosis. Recovery can take weeks or months and may involve rehabilitation, medication to manage symptoms like seizures, and ongoing monitoring by a veterinarian.
