The dog can have a headache too: these are the symptoms

As people who suffer from headaches, we've always been curious whether dogs experience this problem too. And if they do, how can we notice it and help them?

Veterinarians agree that dogs can also suffer from headaches, but it is indeed very difficult to diagnose. In today’s article, we rely on the advice of Dr. Jerry Klein, the chief veterinarian of the AKC. Let’s see what can cause headaches in dogs, what the signs are, and how we can help them in such cases.

A useful study on dogs headaches

Research on headaches in dogs is still quite limited. Among the few available studies is a 2013 investigation that reported evidence of migraine-like episodic pain in dogs. According to the study, owners observed that the dog became quiet, reluctant to interact with anyone, and appeared to be fearful. Following this period, the dog exhibited signs of pain and discomfort, such as vocalization, keeping its head low, and refusing food and water. These symptoms persisted for a few days before the dog returned to its normal state.

These migraine-like episodes can occur at any time. There were no obvious events or environmental factors that preceded their onset. Nevertheless, dogs may be sensitive to things that typically trigger migraines in humans, such as loud noises, bright lights, and strong smells. It is also possible that sensitivity to weather changes triggers the symptoms. In any case, the fact remains that it is not easy to detect such a problem in dogs

Headaches in dogs and signs

It is believed that the signs of headaches in dogs generally overlap with many other symptoms. These can include:

• Lethargy,
• Sensitivity when the neck and head are touched,
• Avoidance of movement or play,
• Nausea,
• Sensitivity to light,
• The dog covering its head or applying pressure to it in some way,
• Trembling.

Given that these are general signs, you cannot determine solely from them whether your dog has a headache or another issue. However, if you notice any of these symptoms and observe a change in your dog’s behavior, it is important to consult a veterinarian. Only a vet can accurately diagnose your pet.

Possible causes of headaches

Dr. Klein explains that the potential causes of headaches in dogs are determined based on the known causes of headaches in humans. In people, there are two types of headaches: primary and secondary. Primary headaches can be caused by an overstimulated brain or issues with the blood vessels and nerves in the head. Secondary headaches are caused by an underlying condition that activates the pain centers in the head. Such conditions might include ear infections, dental infections, sinus infections, high blood pressure, glaucoma, fever, dehydration, inflammatory brain conditions, toxoplasmosis, blood clots, stroke, or brain tumors, among others. These can also occur in dogs. Encephalitis, which can affect both humans and dogs, further supports the theory that our four-legged friends may experience this symptom. The response to medications used to treat headaches in dogs also supports this idea.

Diagnostic tests and MRI can help analyze diseases such as encephalitis and brain tumors, which are known to cause headaches in humans. However, an MRI may not necessarily reveal abnormalities if a dog is experiencing general headaches. Instead, the veterinarian should look for other signs of pain, such as an increased heart rate or discomfort when the head is palpated,” explained Dr. Klein.

Treatment and relief of headaches in dogs

Dr. Klein emphasized that you should never give your dog medication if you suspect it has a headache, especially not human medications. Medications such as ibuprofen, aspirin, and naproxen can be toxic and even fatal to animals. While acetaminophen may be safe for dogs in appropriate doses, only a veterinarian can determine the correct dosage. The dog’s size and overall health also play a significant role.

Regular routine check-ups can help prevent ear, dental, and other issues that might contribute to headaches.

In warmer months, ensure that your dog does not overheat and remains well-hydrated to prevent dehydration and associated headaches. Additionally, check your dog’s collar and harness to ensure they are not too tight. You should be able to comfortably fit two fingers underneath. This prevents pressure on the dog’s spine, which can be especially problematic for growing puppies and overweight dogs.
