Canine distemper is not contagious to humans. Canine distemper is caused by canine distemper virus, which mainly infects canines and cannot be transmitted to humans, so there is no need to worry about dogs infecting themselves. However, canine distemper is extremely contagious to dogs. This disease is spread through dog saliva, urine and other body fluids. If there is more than one dog at home, the owner must be isolated and treated in time to avoid infection.

Methods to identify whether a dog has canine distemper:

1. The simplest method: use a canine distemper test paper to check whether the dog has canine distemper.

2. Measure body temperature to see if there is bidirectional fever: Usually canine distemper is no different from a common cold at the beginning. Check the dog's temperature every six hours to see if it has a fever in the morning and evening and is better at noon. An increase in body temperature in the morning and evening is an obvious characteristic of canine distemper.

3. Cracked paw pads and nose: Many dogs in the early stages of canine distemper have this condition, which is very different from a cold.

4. Increased secretions from the nose and eyes: Although colds can cause runny noses and tears, the sticky secretions are not that much. People with canine distemper have so much secretions around their eyes that they can even cause irritation. Sticky eyes are also obviously different from a cold.
