Canine Distemper

ASPCA logoCanine distemper is a virus that affects a dog’s respiratory, gastrointestinal, respiratory and central nervous systems, as well as the conjunctival membranes of the eye.

What Are the General Symptoms of Canine Distemper?

The first signs of canine distemper include sneezing, coughing and thick mucus coming from the eyes and nose. Fever, lethargy, sudden vomiting and diarrhea, depression and/or loss of appetite are also symptoms of the virus.

How Do Dogs Get Canine Distemper?

The virus is passed from dog to dog through direct contact with fresh urine, blood or saliva. Sneezing, coughing and sharing food and water bowls are all possible ways for the virus to be passed on.

When Is it Time to See the Vet?

Immediately! Please see your vet right away if you suspect your dog has been infected with the canine distemper virus. The virus spreads rapidly and must be aggressively treated as soon as it’s discovered.

How Is Canine Distemper Diagnosed?

Canine distemper tests do exist, but the results alone are not always reliable. Rather than just testing for the infection, your vet has to look at the whole picture, including a dog’s specific symptoms and health history. Positive results can help confirm an infection, but a dog can still be infected even if test results are negative.

Which Dogs Are Prone to Canine Distemper?

Puppies and adolescent dogs who have not been vaccinated are most vulnerable to the distemper virus. They are typically rescues with unknown vaccination histories or have been bought from pet stores.

Serious infections are most often seen in puppies or adolescent dogs. Puppies younger than seven weeks, born to mothers who haven’t been vaccinated against the virus, are extremely susceptible. Once infected, puppies are severely weakened. Often the virus travels to the brain, causing seizures, shaking and trembling. A weakened immune system leaves an infected dog open to secondary infections like pneumonia.

How Can Canine Distemper Be Prevented?

Make sure your dog has completed his series of vaccinations. The vaccine for dogs is called the distemper shot. If you have a puppy, make sure he gets his first vaccination at six to eight weeks of age. Be sure to keep him away from any possibly infectious dogs or environments until he’s finished with his vaccinations at four or five months old.

Also, routine cleaning and disinfecting your home (or kennel) will ensure that the virus is not in your dog’s living environment.
