The incubation period of dog rabies varies greatly, with an average of about 20-60 days. First of all, the incubation period of dog rabies can be as long as several months to several years, and the short one is usually only about a week. The length of the incubation period is usually related to the distance between the wound and the central nervous system. Secondly, during the onset of rabies, dogs will have symptoms such as salivation, photophobia, water fear, and attacks on people. It is recommended to isolate the sick dog in time and notify the relevant departments to deal with it.

The causes of dog rabies:

1. The rabies virus mainly exists in the brain tissue and spinal cord of sick dogs. There are also large amounts of viruses in the salivary glands and saliva of sick dogs, and they are excreted out of the body with the saliva.

2. From 10 to 15 days before the clinical symptoms of sick dogs appear, to 6 to 7 months after the symptoms disappear, the virus can be contained in the saliva. Therefore, when the animal is bitten by a sick animal, Infection can occur.

3. Some healthy-looking dogs and cats can also contain viruses in their saliva. When they lick people or other animals, or live with people, they can also infect people.

4. Many wild animals, such as wolves, foxes, deer, bats, etc., can not only become ill and die after being infected with this disease, but can also expand the spread. For example, some species of bats (African vampire bats) often attack humans and animals after being infected with rabies virus, causing them to become infected.

5. Air contaminated by respiratory secretions and urine can also cause respiratory infections in humans and animals. Wild animals can become infected through their digestive tract by eating diseased carcasses.
