Small red dots on the skin after being bitten by a dog are usually caused by the rupture and bleeding of the capillaries under the skin, resulting in red dots under the skin, which are generally unlikely to subside completely within a day, and the bleeding under the skin can only subside completely in about 3-7 days. If local rabies virus infection is ruled out, local hot compresses or physical therapy, such as infrared therapy, microwave therapy, etc. can promote local blood circulation and speed up the absorption of local bruises, and oral medications to promote blood circulation and resolve blood stasis, such as Ginseng San Qi tablets, Dan Qi capsules, etc., all have a role in promoting and absorbing. If there is obvious skin damage after a dog bite, or bleeding wounds, you must go to the hospital for rabies vaccination after strict disinfection of the wound, in order to prevent rabies attacks as much as possible, once rabies attacks, the mortality rate is 99.99%.
