Per 
SCP-
Fido
Takes the form of the viewer’s favorite animal (can do this for multiple different viewers at once taking shape of multiple animals depending on viewer preference)
Has a collar that has the word: Fido on it, if touched and or if attempted to remove (directly or indirectly) will send the scp into a state of blind rage and the scp’s eyes will no longer be viewable until it’s target is dead. During this phase it remains immune to any means of damage used to this point, and will break through any obstacle with ease (acting as if it is still running through air even if the obstacle is made of concrete)
After killing it’s target, it’s eyes will return and it will seem undisturbed as if nothing happened, this is believed to be a form of a memory wipe
It is also worth mentioning that when not in a state of rage, it remains vulnerable to all means of damage and will act the same as the animal it is being perceived as, if it is being perceived as a lizard, for example, it will take on the likes and dislikes of a lizard
Special containment procedures: all containment cells used to hold scp-(placeholder) have been slowly melted away until after 3 months when it’s containment chamber would be completely destroyed and/or unusable however, recent tests have shown no deterioration to a containment chamber made of wood containing: a wooden rocking chair, two dog bowls, a television on a small wood dresser set to any channel other than static, an empty fireplace, a dog pillow and a small lounge chair. This is believed to be a result of it’s previous habitat although further studying will be made to determine whether that is true or false.
SCP-(placeholder)’s diet: SCP-(placeholder) will refuse to eat anything other than human flesh (preferably male), other than gender, nothing else seems to determine it’s enjoyment of the meal, however an interesting observation made recently has shown that SCP-(placeholder) will eat its meal without needing to be fed, it is not known where SCP-(placeholder) gets a hold of such quantities of human flesh, since it comes from seemingly out of thin air, despite all of the security cameras in it’s containment chamber, none have recorded how SCP-(placeholder) gets this amount of human flesh, although extensive research is being made to find out.
SCP-(placeholder)'s daily routine consists of: waking up around 6:00 in the morning and running around the lounge chair in it’s containment chamber before eating its breakfast, it then lies on the dog pillow until 12:00 at which point it eats its lunch and then runs around the containment chamber until it gets tired or passes out and then a few minutes later it goes back to the dog pillow and rests until 8:00 at which point it eats its dinner and then sits on the lounge chair for 3-4 hours after which point it will return to the dog pillow and repeat the same cycle the next day.
It is believed that the original form of SCP-(placeholder) is supposed to be a dog despite its varied appearance for most of the people who look at it. Given the fact that most people have differing favorite animals the only scientists, guards and D-class personnel allowed in proximity to SCP-(placholder) must fill out a forum of their favorite animal and if it is a dog or wolf (only because of it’s docile nature) or cat. If they do not answer truthfully, they will get severely punished or terminated.
