Why Do Dogs With Rabies Die After Biting


Why Do Dogs With Rabies Die After Biting?

Rabies is a viral disease that affects the nervous system of mammals, including dogs and humans. It is almost always fatal once symptoms appear, and unfortunately, dogs with rabies often die shortly after biting. Here are some key reasons why this happens:

1. Transmission of the virus: Rabies is primarily transmitted through the saliva of an infected animal. When an infected dog bites another animal or human, the virus is introduced into the victim’s bloodstream, rapidly spreading throughout their body.

2. Rapid replication: Once inside the body, the rabies virus quickly replicates and travels to the brain and spinal cord. This process occurs within days or weeks, leading to severe inflammation of the brain, known as encephalitis.

3. Neurological damage: Rabies causes significant damage to the central nervous system, leading to a variety of symptoms, including aggression, anxiety, disorientation, and paralysis. As the disease progresses, the dog’s ability to eat, drink, and breathe becomes impaired.

4. Lack of effective treatment: Unlike many other viral diseases, there is no effective treatment for rabies once symptoms appear. Once a dog shows clinical signs, the chances of survival are extremely low. This is why it is crucial to vaccinate dogs against rabies to prevent its onset.

5. Zoonotic potential: Rabies is a zoonotic disease, meaning it can be transmitted from animals to humans. Infected dogs pose a significant risk to humans as they may bite or scratch, facilitating the transmission of the virus. To protect both animals and humans, any suspected rabid dog should be immediately quarantined or euthanized.

6. Unpredictable behavior: As the disease progresses, dogs with rabies may exhibit aggressive and unpredictable behavior, including biting. The neurological damage caused by the virus affects the dog’s normal behavior patterns and inhibitions, making them more likely to bite without warning.

7. Importance of prevention: Vaccination is the most effective way to prevent rabies in dogs. By vaccinating domestic dogs, we can create a barrier between the virus and humans, reducing the risk of transmission. Vaccination also helps control the spread of rabies within the dog population.

8. Public health concern: Rabies remains a significant public health concern in many parts of the world. It is estimated that rabies causes tens of thousands of human deaths globally each year. Controlling the disease in dogs is crucial to reducing the risk of human infection and preventing unnecessary deaths.


1. Can dogs survive rabies if treated early?
No. Once symptoms appear, there is no effective treatment, and the disease is almost always fatal.

2. How is rabies transmitted to humans?
Rabies is primarily transmitted through bites or scratches from infected animals.

3. Can a vaccinated dog get rabies?
It is highly unlikely for a vaccinated dog to get rabies, but no vaccine is 100% effective, so precautions should still be taken.

4. Can humans survive rabies?
Survival is extremely rare once symptoms appear, making prevention through vaccination crucial.

5. How long does it take for rabies symptoms to appear in dogs?
The incubation period varies but usually ranges from three to eight weeks, although it can be as short as a few days or as long as several years.

6. Can a dog transmit rabies without biting?
Yes, rabies can also be transmitted through saliva contact with open wounds or mucous membranes.

7. Can rabies be cured in dogs if caught early?
There is no known cure for rabies once symptoms appear, regardless of how early it is detected.

8. Can you get rabies from a dead dog?
Rabies is not transmitted by handling or being near a dead animal. However, avoid touching the brain tissue or saliva of a potentially rabid animal.
