Per 
Special Containment Procedures: SCP-8174 is to be kept in a locked container at all times and devoid of all kinds of light except artificial. When exposed to any natural light sources, it will enter a state of rage and go on a rampage until it is recontained.
Desciption: SCP-8174 is a muscular, humanoid entity around 2,30m with long arms and covered by fur. It seems to be wearing the skull of an unknown canine animal, though X-rays suggest that it belongs to SCP-8174.
DNA blood samples suggests that it is partially human, though DNA belonging to other animals, such as chimpanzees, mice, dogs and horses have been found.
SCP-8174 seems to have an extraordinary ability to regenerate. It has been observed growing back limbs and muscle tissue in just a matter of seconds.
This ability to regenerate makes it hard to recontain SCP-8174 once it breaches containment, since it also seems to make it unkillable, eliminating the option of executing SCP-8174.
Should SCP-8174 breach containment it is to be frozen by liquid nitrogen injected directly into the bloodstream via poison darts and be re-contained at Site-██.
