Meningitis in dogs is a neurological disease that causes inflammation of the protective membranes, called the meninges, that surround the central nervous system.
Meningitis may also cause secondary inflammation in the brain or spine. Meningoencephalitis a similar condition that affects the mind and the meninges, while meningomyelitis a condition that affects the spinal cord and the meninges.
These can sometimes have different causes but present similar symptoms to meningitis in dogs. If you notice the symptoms of meningitis in your dog, then it’s important that you see a veterinarian right away.
Symptoms can be severe when it goes untreated, and meningitis may lead to other serious conditions in dogs, including neurological problems like seizures and paralysis.
Here’s what you should know about the symptoms, causes, and treatments for meningitis in canines. In some cases, it can end up being fatal.
Symptoms Of Meningitis In Dogs
The symptoms of meningitis in dogs may vary in type and intensity depending on how far the inflammation progresses and which parts of the central nervous system are affected.
Initial symptoms may include the following:
- Neck or back pain or stiffness in the spine, noticeable by your dog holding their neck or back rigid
- Muscle spasms in the back, neck, or forelegs
- Eyes tracking from side to part or up and down
- Sensitivity to touch
- Weakness
- Head tilting
- Unsteadiness while walking
- Depression
- Vomiting
- Loss of appetite
- Fever
- Low blood pressure
Serious symptoms that tend to occur if the disease progresses include the following:
- Blindness
- Dullness or stupor
- Severe unsteadiness or loss of muscle control
- Seizures
- Paralysis
- Confusion or disorientation
- Abnormal levels of aggression or agitation
It’s important to see a veterinarian right away if you notice these symptoms. The earlier treatment begins, the more effective it will be, and the better the chances of recovery are for your dog.
Causes Of Meningitis In Dogs
The most common cause of meningitis in dogs is really a bacterial infection that starts somewhere else in the body and migrates to the central nervous system. This then causes inflammation of the protective meninges that results in meningitis.
The cause need not be bacterial, however. Infections due to viruses, parasites, or fungi can lead to infections in the central nervous system that result in meningitis.
Here are a few infections that may result in meningitis:
- Ear, eye, sinus, or nasal infection
- Infection from an injury
- Rabies
- Distemper
- Lyme disease
- Vertebral disk infections
- Bone infections in the spinal area
- Rickettsia
The disease may also result from exposure to toxins or from auto-immune disease. Dogs with weakened immune systems, like puppies, are at further risk.
It may also have a genetic component, as certain breeds are more predisposed to the condition. These include Beagles, Bernese Mountain Dogs, Maltese, and Pugs.
In other cases, the cause can simply not be identified at all.
Treatments For Meningitis In Dogs
Goals of treatment for meningitis in dogs include suppressing the inflammation, encouraging recovery from neurological conditions brought on by the disease, relieving pain, and controlling seizures. Treatment can vary depending on the cause of the inflammation.
Most of the time, treatment begins with administration of steroids to suppress the immune system response that causes inflammation. These are often given orally and reduce swelling around the brain.
Steroids are especially important when the cause of meningitis an autoimmune disease where the dog’s immune system attacks the body’s own tissue.
In cases of infection, a veterinarian may use antibiotics, sometimes intravenously to increase their effectiveness. Antibiotics are also helpful in preventing secondary infection, which a dog is more susceptible to when they’re being treated with steroids that suppress the immune system. This type of treatment can be long-term.
Additionally, anti-epileptic drugs may be used to reduce seizures, and intravenous fluid might be given to dogs who are unable to feed or drink for themselves. Pain medication may also be given to dogs to improve comfort. Bed rest and nursing care are important during the time of recovery, which can take four weeks or more.
The overall likelihood of recovery can vary depending on the cause of the meningitis and what lengths it has progressed. Although, for infections that have reached the central nervous system, the prognosis is not good.
Sadly, many dogs die from these types of infections. Dogs’ responses to treatment, however, may differ greatly, and early and aggressive medical intervention always improves the odds of recovery.
