What is Canine Distemper?

How is Canine Distemper virus spread?

What dogs are at risk?

Canine distemper is a highlycontagious and serious diseasecaused by a virus that attacks therespiratory, gastrointestinal, and,often, the nervous systems ofpuppies and dogs. The virus alsoinfects wild canids (e.g. foxes,wolves, coyotes), raccoons, skunks,and ferrets.

Puppies and dogs usually become infected through airborneexposure to the virus contained in respiratory secretions ofan infected dog or wild animal. Outbreaks of distemper tendto be sporadic. Because canine distemper also affects wildlifepopulations, contact between wild canids and domestic dogsmay facilitate spread of the virus.

All dogs are at risk but puppies younger than four monthsold and dogs that have not been vaccinated against caninedistemper are at increased risk of acquiring the disease.

What are some signs of Canine Distemper? The first sign of distemper is eye discharge that may appearwatery to pus-like. Subsequently, dogs develop fever, nasaldischarge, coughing, lethargy, reduced appetite, vomiting,and diarrhea. In later stages, the virus may attack the nervoussystem, bringing about seizures, twitching, or partial orcomplete paralysis. Occasionally, the virus may cause footpadsto harden. Distemper is often fatal. Even if a dog does notdie from the disease, canine distemper virus can causeirreparable damage to a dog’s nervous system. Distemper isso serious and the signs so varied that any sick dog shouldbe taken to a veterinarian for an examination and diagnosis.

How is Canine Distemper diagnosed and treated? Veterinarians diagnose canine distemper on the basis ofclinical appearance and laboratory tests. No specific drugis available that will kill the virus in infected dogs. Treatmentconsists primarily of efforts to prevent secondary infections;control vomiting, diarrhea, or neurologic symptoms; andcombat dehydration through administration of fluids. Illdogs should be kept warm, receive good nursing care, andbe separated from other dogs.

How is Canine Distemper prevented? Vaccination and avoiding contact with infected animals arekey elements of canine distemper prevention.

Vaccination is important. Young puppies are very susceptibleto infection, particularly because the natural immunityprovided in their mothers’ milk may wear off before thepuppies’ own immune systems are mature enough to fightoff infection. If a puppy is exposed to canine distemper virusduring this gap in protection, it may become ill. An additionalconcern is that immunity provided by a mother’s milk mayinterfere with an effective response to vaccination. Thismeans even vaccinated puppiesmay occasionally succumb todistemper. To narrow gaps inprotection and optimally defendagainst canine distemper duringthe first few months of life, aseries of vaccinations isadministered.

Until a puppy has received itscomplete series of vaccinations,pet owners should use cautionwhen taking their pet to placeswhere young puppies congregate (e.g. pet shops, parks, puppyclasses, obedience classes, doggy daycare, and groomingestablishments). Reputable establishments and trainingprograms reduce exposure risk by requiring vaccinations,
