I was bitten by a dog four days ago. the dog seems healthy.my throat feels a little painful and saliva increases at night.have i contracted rabies?

Likely not: Too short an incubation period and a healthy dog. Has the pooch been immunized? See your doc.

Probably not : Probably not but contrary to popular belief, a dog's mouth is not clean or sterile. I would see a doctor especially if you are running a fever or if the dog bite looks infected.

Low chance: If you were bitten by a healthy daog you are not in danger of rabies. Certainly follow up with the owner of the dog and make certain that the dogs had its rabies shot if the dog did not then the dog will need to be quarinted. See to your doctor about the dog bite and make sure you do not have an infection in the bite.
