Dogs can indeed get headaches. While research on canine headaches is limited and dogs cannot communicate their pain verbally, veterinarians and animal experts generally agree it's possible based on similarities in anatomy and physiology between dogs and humans. Dogs can suffer headaches caused by issues like sinus problems, ear infections, dental issues, head trauma, brain tumors, dehydration, stress, environmental factors (like bright lights or loud noises), allergies, and underlying health conditions. Signs that a dog might have a headache include behavioral changes such as lethargy, sensitivity to touch around the head or neck, pawing at the head, restlessness, changes in appetite, shaking, avoiding light and strong smells, and carrying or pressing the head against objects. Head pressing in dogs is a serious symptom that requires immediate veterinary attention. Overall, headaches in dogs are plausible, though diagnosis is challenging and usually depends on observing symptoms and ruling out other health issues with veterinary help.
