Early signs of rabies in animals include a
change in behavior, fever, loss of appetite, and often, a change in
phonation, such as a change in tone of a dog's bark. These signs are
often slight, however, and people may not notice them. A few days
after infection, the animal may be very restlessness and become very
agitated and tremble. An affected dog may growl and bark constantly,
and will viciously attack any moving object, person, or animal it
comes across. This excited state usually lasts three to seven days,
and is followed by convulsions and paralysis.
instances, signs of excitement and irritability are slight or
absent, and paralysis develops within a few days of disease onset.
In cases of this type, an early sign is often paralysis of the lower
jaw, accompanied by increased drooling and foaming of saliva. The
animal may appear to be choking on a foreign object. This is a
dangerous trap for humans, who, in trying to help the animal, may
expose themselves to infection without knowing it.
