85Canine distemper is a highly contagious viral disease affecting dogs, but it cannot be transmitted to humans. The virus causes fever, respiratory issues, gastrointestinal problems, and neurological symptoms in dogs. Early signs include dry nose, lethargy, and loss of appetite. Vaccination is the most effective prevention method.
Canine distemper is an acute, highly contagious disease caused by the canine distemper virus. Symptoms occur in two phases: initial fever and leukopenia, followed by severe respiratory, gastrointestinal, and neurological symptoms. The disease progresses through distinct stages over 2-14 days.
How dogs contract canine distemper:
- Primarily spreads through respiratory droplets from infected dogs
- Can also transmit via contaminated food, water, or objects
- Common in high-density dog populations like kennels
- More prevalent during colder months (October to April)
The virus spreads through:
- Bodily fluids including nasal discharge, saliva, and urine
- Contaminated surfaces and shared items
- Airborne transmission in close quarters
While the disease is severe for dogs, it poses no risk to human health. The virus cannot infect humans, though it shares some transmission similarities with human diseases. Prevention focuses on vaccination and avoiding contact with infected dogs. Puppies should receive their first vaccine at 6-8 weeks, with boosters following veterinary guidelines.
If you suspect your dog has distemper:
- Isolate them from other dogs immediately
- Contact your veterinary practice for advice
- Monitor symptoms closely (temperature, appetite, behaviour)
- Follow strict hygiene to prevent spreading to other pets
