Rabies is a virus that is transmitted by the bite of an infected animal. The main carrier North America is the skunk, fox, raccoon and bat.
The incubation period can be from ten days to one year or longer. In dogs, the period is typically two weeks to four months. How quickly signs develop depends on the severity of the bite and the site of infection. If the bite is close to the brain and spinal cord the quicker it reaches the nervous tissue.
Signs of Rabies
Rabies develops in two stages. In the first stage the dog will show a definite change in temperament. Quiet dogs become agitated and active pets become nervous or shy.
After that, there are two “forms” of rabies:
Furious rabies: The dog becomes highly excitable with a ravenous appetite. The dog may eat and chew stones, dirt, etc. Paralysis will follow and the dog may not be able to eat or drink. The dog will eventually start having violent seizures and die. Contrary to popular belief, hydrophobia (fear of water) is not a sign of rabies in dogs, only humans.
Dumb rabies: The more common form in dogs. Signs may be paralysis in the limbs and face. The face will become distorted and the dog may have difficulty swallowing. It may appear that the dog has something stuck in the mouth or throat. Care should be taken in examination since rabies may be transmitted by saliva. Ultimately the dog becomes comatose and dies.
Is vaccination effective?
Vaccination promotes the production of antibodies but is only effective if given before the virus enters the nervous system. Modern rabies vaccines for dogs are extremely safe and effective.
What is the treatment for rabies?
There is no treatment for a dog with rabies. If rabies is suspected, the dog has to be kept in isolation. Your veterinarian is required by law to notify the local and state animal disease authorities. They will determine the steps necessary to properly protect the public.
Can humans catch rabies?
Yes, the disease can be transmitted from an animal to man. It is only transmitted by the bite of a rabid animal. The virus is present in the saliva of the infected animal only for a limited time.
