Abstract: Clostridium tetanus can cause infection after invading the organism through wounds and damaged mucous membranes，mainly manifesting as increased stress of motor nervous system and continuous spasm of muscles throughout the body，with a high mortality. In this paper，we report a case in which a dog’s hind limb was pinched by a rusty rat clip. After clinical observation，combined with laboratory tests such as blood routine examination， biochemical examination and laboratory examination of wound secretions，Clostridium tetani infection was diagnosed and treated symptomatically，resulting in the dog's recovery.
