Per 
Containment: SCP-5057 is kept at site-19 in an 6 meters by 6 meters by 6 meters room made with 3 feet thick concrete walls plated with tank armor on the inside and must be monitored and occupied at all times using small toys fitted with cameras and meat in large amounts. When being fed SCP-5057 must be put unconscious with nerve agents and all food must be put in through a 1 foot by 1foot hole that must imminently be resealed. In the case that SCP-5057 managed to escape the are should be evacuated of all personal and SCP's that are easily accessible while the nerve agent is deployed, personal equipped with protection against the nerve agent should put SCP-5057 back into containment. If SCP-5057 makes it out of the facility then a group of tanks with titanium armor should be deployed (due to titanium being the only known material that can stop SCP-5057) that will give time for more nerve agents to be deployed by a bomber.
Description SCP-5057 appears to look like a furless dog the size of a horse with a stubby snout the contains a barbed tongue that reaches lengths of 5 meters. its teeth look like canine teeth but are the size of a small combat knifes. SCP-5057 has 2 eyes but these have been found to be useless as it uses sound and smell to find creatures and objects. It is noted that the creature can be distracted using toys. camera footage has shown that SCP-5057 eats by cutting its prey into long strips with its claws and then eating them.
