After more than a decade working as a small-animal veterinarian, I’ve learned that dog owners notice subtle changes in their pets long before a problem becomes obvious. One question that comes up surprisingly often is simple: Do dogs get headaches?
The short answer is yes—dogs can experience headaches. But explaining how we recognize them, and what causes them, is a little more complicated. Dogs can’t tell us their head hurts, so we rely on behavior, physical exams, and sometimes diagnostic testing to connect the dots.
Over the years, I’ve seen several cases that strongly suggested headaches were part of the problem. Some were mild and temporary. Others turned out to be signs of deeper medical issues.
Why Veterinarians Believe Dogs Can Have Headaches
Biologically, there’s no reason dogs wouldn’t experience headaches. Their nervous system is very similar to ours. They have pain receptors, blood vessels, muscles around the skull, and neurological pathways that can produce head pain.
In clinical practice, we often see conditions known to cause headaches in humans—such as sinus infections, dental disease, high blood pressure, or neurological inflammation—also occur in dogs. When a dog with one of those conditions shows signs of head sensitivity or unusual behavior, headaches become a reasonable explanation.
I remember a middle-aged Labrador that came into the clinic one summer because he had suddenly started hiding in a dark corner of the house. His owner described him as normally energetic and social. But over the previous week, he avoided light, slept more than usual, and flinched when his head was touched.
After examining him and running a few tests, we discovered a severe sinus infection. Once the infection was treated with medication, the dog’s behavior returned to normal within days. Situations like that are a strong reminder that head pain in dogs is very real—even if they can’t describe it.
Signs a Dog Might Be Experiencing Head Pain
Dogs don’t rub their temples or say they feel pressure behind their eyes. Instead, they communicate discomfort through changes in behavior.
In my experience, several patterns recur when a dog may be dealing with a headache.
A dog may become unusually quiet or withdrawn. Owners sometimes describe their pet as “not acting like themselves.” The dog might avoid interaction, seek out dark or quiet spaces, or sleep more than usual.
Sensitivity around the head is another clue. I’ve had patients pull away when someone tries to pet their forehead or ears. Some dogs will squint or keep their eyes partially closed, especially in bright environments.
A few dogs develop sudden irritability. A normally patient dog might growl or snap if their head is touched.
One case that stands out involved a young Border Collie brought in by an owner who thought the dog had developed a behavior problem. The dog had begun snapping when children tried to hug him. During the exam, I noticed the dog winced whenever pressure was applied around his upper jaw. The problem turned out to be an infected tooth that had spread inflammation toward the sinus cavity. After dental treatment, the snapping behavior disappeared.
Situations like that remind me how easily pain can be mistaken for temperament.
Conditions That Can Cause Headaches in Dogs
Headaches themselves are rarely the primary diagnosis. More often, they’re a symptom of something else.
Sinus infections are one of the most common triggers. Dogs with inflamed sinuses may experience pressure similar to that felt during severe congestion.
Dental disease can also contribute. Infected teeth—especially the upper molars—sit close to the sinus cavities and can create significant facial pain.
Ear infections can sometimes cause head discomfort. In chronic cases, inflammation can spread deeper into nearby tissues.
Another cause I’ve encountered is high blood pressure. This is more common in older dogs or those with kidney disease. Elevated blood pressure can cause headaches, as it does in humans.
In rare situations, neurological conditions such as brain inflammation, trauma, or tumors may cause persistent head pain. These cases typically come with additional symptoms such as balance issues, seizures, or abnormal eye movements.
Fortunately, those severe causes are far less common than infections or dental problems.

The Subtle Clues Owners Often Miss
One of the hardest parts of diagnosing headaches in dogs is that the signs can be subtle.
I often ask owners a few specific questions during appointments:
Has your dog been hiding more than usual?
Do they avoid bright light or noisy environments?
Have they become sensitive about being touched around the face or ears?
Sometimes owners pause and suddenly connect the dots. I recall a client who realized her dog had been sleeping under the bed for several days, rather than in his usual spot by the window. That small change helped point us toward a sinus infection that required treatment.
Dogs are remarkably good at masking discomfort. By the time symptoms become obvious, the underlying issue may have been present for a while.
Common Mistakes I See Dog Owners Make
One mistake I see repeatedly is assuming behavioral changes are purely emotional or training-related.
A dog that suddenly becomes irritable, withdrawn, or sensitive may be dealing with pain. It’s easy to label the behavior as stubbornness or anxiety when the real issue is medical.
Another common problem is giving human pain medication. I’ve treated several dogs that became ill after their owners gave them medications meant for people.
Some common human pain relievers are toxic to dogs and can cause serious organ damage. Even seemingly harmless medications can be dangerous without veterinary guidance.
If a dog seems uncomfortable, the safest approach is to have them examined rather than guessing.
What Happens During a Veterinary Visit
When I suspect a dog might be experiencing head pain, I start with a detailed physical exam.
This includes checking the teeth, sinuses, ears, and eyes. I gently palpate areas of the skull to see whether certain spots trigger sensitivity.
If the cause isn’t obvious, further tests might be needed. Blood tests can reveal infections or organ problems. Imaging—such as X-rays or advanced scans—may help identify deeper issues affecting the skull or brain.
In many cases, though, the cause becomes clear during the initial exam.
Treating the underlying problem typically resolves the headache.
When Owners Should Seek Help
A single quiet afternoon probably isn’t cause for alarm. Dogs, like people, have off days.
But certain patterns should prompt a veterinary visit. Persistent lethargy, sensitivity around the head, hiding behavior, sudden aggression, or neurological symptoms are all signals that something deeper may be happening.
One older Golden Retriever I treated had been squinting and rubbing his face on the carpet for several days. His owner initially thought it was allergies. During the exam, we discovered advanced glaucoma causing severe pressure behind the eye. Quick treatment likely saved the dog’s vision.
Cases like that reinforce the value of early evaluation.
Living With a Dog That May Experience Head Pain
Once the underlying issue is treated, most dogs recover fully. In cases tied to chronic conditions—such as recurring sinus infections or hypertension—management becomes the focus.
Owners often help by paying attention to small behavioral changes. Dogs communicate through body language more than anything else, and subtle shifts can reveal discomfort long before obvious symptoms appear.
In practice, I’ve found that attentive owners are often the best diagnostic tool we have.
Dogs may never tell us their head hurts, but they show us in other ways. Recognizing those signals early can make all the difference in helping them feel better.
