What Is Distemper in Dogs? Canine distemper is a highly contagious viral disease in dogs that affects the respiratory, gastrointestinal, and nervous systems, and it can be fatal if not treated.
The virus spreads through contact with infected animals or their secretions and can be prevented through vaccination.
Recognizing the symptoms early and ensuring proper vaccination is key to protecting your dog from this serious illness.
How Dogs Get Distemper
Distemper is caused by the canine distemper virus (CDV), which is similar to the measles virus in humans.
Dogs usually contract the virus by coming into contact with an infected animal’s respiratory secretions, such as sneezes or coughs, or by sharing food or water with an infected dog.
Wild animals like raccoons and foxes can also carry the virus, making it a threat to unvaccinated dogs that spend time outdoors.
How Is Canine Distemper Spread?
Canine distemper can be transmitted through several means:
- Direct Contact: Dogs can contract the virus by coming into direct contact with an infected animal or contaminated object.
- Airborne Exposure: The virus can be spread through the air, similar to how humans spread the common cold. Infected dogs or wild animals release aerosol droplets when they cough, sneeze, or bark, which can infect nearby animals and surfaces, such as food and water bowls.
- Placental Transmission: Infected mother dogs can pass the virus to their puppies through the placenta.
Although the virus does not survive long in the environment and is easily eliminated by most disinfectants, infected dogs can shed the virus for several months, posing a risk to nearby dogs.
Additionally, wild animals like raccoons, foxes, and skunks can also carry the virus, which means local outbreaks in wildlife can endanger dogs even if they do not interact with other dogs.
It is crucial to fully vaccinate any dog intended for breeding to prevent transmission to puppies

Symptoms of Canine Distemper
The symptoms of distemper can vary depending on which body systems are affected. Early signs of distemper may be mistaken for other, less severe illnesses, making early detection and veterinary intervention crucial.
Respiratory Symptoms
In the early stages, distemper affects the dog’s respiratory system, causing symptoms similar to kennel cough or other common respiratory infections.
- Coughing: A reflex action to clear the throat or airways; in dogs, it can indicate irritation or infection in the respiratory tract.
- Sneezing: An involuntary expulsion of air from the nose and mouth; often a sign of nasal irritation or infection.
- Nasal Discharge: Fluid that flows from the nostrils; can be clear, cloudy, or colored, indicating possible infection or inflammation.
- Fever: An elevated body temperature, typically above 102.5°F (39.2°C); can indicate infection or illness in dogs.
Gastrointestinal Symptoms
As the virus progresses, it may affect the gastrointestinal system, leading to more severe symptoms.
- Vomiting: The act of expelling the contents of the stomach through the mouth; can be a sign of illness or irritation in the digestive tract.
- Diarrhea: Loose or watery stools; can lead to dehydration and indicates gastrointestinal distress.
- Lack of Appetite: A decreased desire to eat; can be a sign of various health issues, including infections.
- Dehydration: A condition that occurs when the body loses more fluids than it takes in; can lead to serious health issues if not addressed.
Neurological Symptoms
In advanced cases, distemper can invade the nervous system, causing life-threatening neurological issues.
- Seizures: Sudden, uncontrolled electrical disturbances in the brain, leading to convulsions or altered behavior.
- Twitching (Myoclonus): Involuntary muscle contractions or spasms; can be a sign of neurological involvement.
- Paralysis: The loss of ability to move one or more parts of the body; can indicate severe neurological damage.
- Loss of Coordination: Difficulty in controlling movements, leading to clumsiness or instability; often indicates neurological impairment.
Early recognition of these symptoms and prompt veterinary care are essential for the best possible outcome in dogs affected by distemper.

How Is Distemper Diagnosed?
If your dog exhibits signs of distemper, seeking veterinary attention promptly is crucial.
The diagnosis of distemper usually involves a combination of clinical observations and laboratory tests.
A veterinarian may conduct blood tests, urine tests, or collect samples from respiratory secretions to verify the presence of the virus.
Common diagnostic methods include blood tests to detect the virus and evaluate the dog’s immune response, as well as PCR testing, which identifies the virus in bodily fluids using a Polymerase Chain Reaction technique.
Dr. Karen Becker, a holistic veterinarian, emphasizes the importance of early vaccination in her article on Mercola Healthy Pets.
She explains that while distemper is preventable, it remains a risk in areas where vaccination rates are low, particularly among stray and shelter dogs.
Early intervention and supportive care significantly improve a dog’s chance of recovery.
Treatment for Canine Distemper
While there is no specific cure for distemper, treatment primarily focuses on symptom management and supporting the dog’s immune system as it combats the virus.
Hospitalization may be necessary for dogs with severe symptoms, such as dehydration or seizures.
Treatment strategies include providing fluids to prevent dehydration caused by vomiting and diarrhea, using antibiotics to address secondary bacterial infections, and administering anticonvulsants to manage seizures.
Additionally, supportive care may involve isolating affected dogs to prevent the virus from spreading to other animals.
Preventing Distemper in Dogs
The most effective way to prevent distemper in dogs is through consistent vaccination.
Puppies should receive their initial distemper vaccination between six to eight weeks of age, followed by booster shots every few weeks until they reach about 16 weeks old.
Adult dogs also need regular booster shots to ensure continued immunity.
To enhance prevention efforts, it’s crucial to follow your veterinarian’s vaccination recommendations, keep unvaccinated puppies and dogs away from areas where they might encounter infected animals—such as dog parks or wild environments—and maintain hygiene by disinfecting shared spaces and items if your dog has been exposed to a potentially infected animal.

According to the American Veterinary Medical Association (AVMA), distemper remains one of the most serious diseases affecting dogs worldwide, particularly in areas with low vaccination rates.
Dr. Jane Sykes, a leading veterinary infectious disease expert, highlights the importance of community-wide vaccination programs to reduce the spread of distemper, particularly in areas with high populations of stray dogs.
She advises that prompt veterinary care and supportive treatments are essential for improving the prognosis in dogs diagnosed with the virus.
Conclusion
Distemper in dogs is a highly contagious and serious viral disease that affects multiple systems in the body, including the respiratory, gastrointestinal, and nervous systems.
While there is no cure for distemper, it can be prevented through regular vaccination and good hygiene practices.
If your dog shows any signs of distemper, immediate veterinary attention is crucial.
With proper care and vaccination, you can protect your dog from this potentially fatal illness.
FAQs
Dogs can recover from distemper with timely medical intervention, although the recovery period may last several weeks or even months, and some dogs may experience lingering neurological effects.
Vaccination schedules for puppies typically begin at six to eight weeks of age, with subsequent booster shots administered until they are 16 weeks old.
For adult dogs, regular booster vaccinations are necessary, generally occurring every one to three years.
Additionally, distemper is highly contagious and can spread among dogs and certain wild animals, such as foxes and raccoons, primarily through respiratory secretions and contaminated surfaces.
