If your veterinarian has recommended a distemper vaccine for your dog, you may wonder what it protects against and why it matters.
Canine distemper is a highly contagious viral disease that can cause serious illness in dogs. It can affect the respiratory, gastrointestinal and nervous systems, and in some cases, it can be fatal.
The distemper vaccine helps protect dogs from this serious disease. It is considered a core vaccine and is recommended for most dogs as part of routine preventive care.
What is canine distemper?
Canine distemper is a contagious viral disease that can affect dogs of all ages. The virus can cause problems in several parts of the body, including the respiratory system, digestive system and nervous system.
Dogs can become infected through close contact with an infected animal or by exposure to respiratory droplets from coughing or sneezing. The virus can also spread through shared food and water bowls or other contaminated objects.
Distemper is particularly concerning because there is no specific cure for the virus itself. Treatment focuses on managing symptoms and supporting the dog’s recovery.
What does the distemper vaccine protect against?
The distemper vaccine helps protect dogs against canine distemper virus.
It is commonly included in combination vaccines that also protect against other serious diseases, such as canine parvovirus and adenovirus. Your veterinarian can explain which combination is appropriate for your dog.
Vaccination does not guarantee that a dog will never become infected, but it greatly reduces the risk of serious illness.
What are the signs of distemper in dogs?
Distemper can cause a range of symptoms, and they may develop at different stages of the infection.
Early signs can include:
- Fever
- Watery to pus-like discharge from the eyes or nose
- Coughing
- Tiredness
- Reduced appetite
- Vomiting
- Diarrhea
As the disease progresses, some dogs can develop neurological signs, such as muscle twitching, seizures, poor coordination or other changes in movement.
If your dog shows signs of serious illness, particularly breathing difficulties, repeated vomiting or diarrhea, seizures or significant weakness, contact your veterinarian promptly.
How do dogs get distemper?
Distemper spreads easily between infected animals.
The virus can spread through respiratory droplets when an infected dog coughs or sneezes. Dogs can also be exposed through direct contact with an infected animal or contaminated objects.
Unvaccinated puppies and dogs are at greater risk, particularly when they spend time around other dogs or in places where infected animals may have been.
Because distemper is so contagious, vaccination is an important way to help protect individual dogs and reduce the spread of the disease.
Which dogs need the distemper vaccine?
The distemper vaccine is considered a core vaccine, meaning it is recommended for most dogs regardless of lifestyle.
This includes dogs that spend most of their time at home. Even dogs that don’t regularly visit dog parks, daycare or boarding facilities can be exposed to infectious diseases.
Puppies are especially vulnerable because their immune systems are still developing. Your veterinarian will recommend an appropriate vaccination plan based on your puppy’s age, health and previous vaccinations.
Adult dogs also need continued protection. Your veterinarian can review your dog’s vaccination history and recommend what they need based on their individual circumstances.
Can indoor dogs get distemper?
Yes. Staying indoors can reduce a dog’s exposure to some infectious diseases, but it doesn’t eliminate the risk.
Dogs may still come into contact with infectious diseases during walks, veterinary visits, travel or contact with other animals. People can also unintentionally bring contaminated material into the home.
This is one reason core vaccines such as distemper are recommended, even for dogs with a relatively low-risk lifestyle.
Is the distemper vaccine safe?
Vaccines are routinely used to protect dogs against serious infectious diseases, and most dogs tolerate them well.
Some dogs may experience mild effects after vaccination, such as:
- Tiredness
- Soreness where the vaccine was given
- A temporary decrease in appetite
- A mild fever
These effects are usually short-lived. Your veterinary team can tell you what to expect after your dog’s vaccination and what signs would warrant a call.
If your dog has had a reaction to a vaccine in the past, let your veterinarian know before their next vaccination.
When should my dog get the distemper vaccine?
The timing of distemper vaccination depends on your dog’s age, vaccination history and individual circumstances.
Puppies typically need a series of vaccinations while they develop protection. Your veterinarian will recommend the appropriate timing based on your puppy’s age and previous vaccines.
Adult dogs also need ongoing protection, although the timing of future doses can vary.

What happens at a distemper vaccination appointment?
Your veterinarian will review your dog’s health and vaccination history before recommending a vaccine. They may also ask about your dog’s lifestyle and any recent changes in their health.
The appointment may include:
- A review of your dog’s vaccination history
- A physical examination
- A discussion about which vaccines are recommended
- Administration of the appropriate vaccine
- Advice about what to expect after vaccination
- Information about when your dog is due for their next vaccines
If you have questions about the distemper vaccine or your dog’s risk of exposure, this is a good time to ask your veterinarian.
Protecting your dog from distemper
Canine distemper is a serious disease, but vaccination provides strong protection against it. Because distemper can spread easily and affect dogs throughout the body, prevention is much safer than waiting for an infection to occur.
Your veterinarian can review your dog’s vaccination history and help you understand which vaccines are appropriate for their age, health and lifestyle.
At Hometown Veterinary Partners, our veterinary teams provide preventive care for dogs and cats and can answer your questions about vaccinations and your pet’s overall health.

Frequently asked questions
Is canine distemper the same as kennel cough?
No, although early symptoms can appear similar to those of kennel cough. Canine distemper is a viral disease that can affect several body systems, while kennel cough is a term used for a contagious respiratory illness in dogs caused by several different infectious agents. It’s important to visit your veterinarian right away if you notice any concerning symptoms.
Can vaccinated dogs still get distemper?
Vaccination greatly reduces the risk of serious illness from canine distemper. No vaccine provides an absolute guarantee, but keeping your dog’s vaccinations up to date is one of the best ways to protect them.
Can puppies get the distemper vaccine?
Yes. Puppies are particularly vulnerable to distemper, so vaccination is an important part of puppy preventive care. Your veterinarian will recommend a vaccination plan based on your puppy’s age and health.
Is distemper contagious?
Yes. Canine distemper is highly contagious and can spread between infected animals through respiratory droplets and direct contact.
Can humans get canine distemper?
No. Canine distemper virus does not infect people. However, people can potentially carry infectious material between animals, so good hygiene is still important when caring for a sick dog.
Is distemper fatal in dogs?
Distemper can be fatal, particularly in dogs that develop severe disease or neurological complications. Vaccination significantly reduces the risk of serious illness.
