This is a crazy idea I just came up with before I fell asleep last night. A very weird idea, but let me know what you think.

DISCLAIMER: I own nothing.

Elliot and Olivia arrived at the front door of Sam Peters, who was suspected of tying up 23-year-old Sara Owens in the woods to a tree and raping her. She did not survive the ambulance ride and all the evidence pointed to Sam. The detectives were here to arrest him.

"Sam, it's the police! Open this door or we'll have to break it down!" Elliot shouted with his gun ready in one hand. Olivia was right behind him with her gun ready to back him up. When Sam did not come to open the door, Elliot flashed Olivia the signal with his other hand and they kicked the door open. The apartment was a mess. Many papers, books, and other items were scattered, but Sam Peters was nowhere to be found.

"Clear!" Olivia shouted from a room down the hall.
"Clear!" Elliot checked the bedroom and found nothing but a terrible mess. "He's gone, El." Olivia caught up to Elliot in Sam's living room.

"I'm going to check out a few rooms."
"I'll be right behind you." Elliot walked carefully to the suspect's bathroom and approached the closed door suspiciously.
"Sam, are you in there? I'm going to kick down the door if you don't come out!" Elliot looked back at Olivia, who smiled and nodded her head to assure her she was ready. He kicked the door open and stared unexpectedly into the bloodshot eyes of a feral dog with bared fangs.

------------------------------------------------

It all happened in a blur, but it seemed the dog had been sitting there and preparing for the detectives to find it. When Elliot opened that door, the dog was ready and lunged for the detective's shoulder. The force of the jump knocked Elliot to the ground. The dog's fangs and claws tore his shirt and skin while Olivia pointed her gun at the dog.
"Elliot!" Olivia screamed as the beast tore into her partner.
"Liv, shoot it!" he cried while struggling with the feral beast on the ground. Olivia pulled the trigger a few times and pumped the dog full of lead but it only seemed to stun the beast.

"Elliot, it's not working!" Elliot kicked the dog across the room and grabbed Olivia's hand.
"In here!" Elliot and Olivia ran into the room next to them and locked the door. Elliot nearly collapsed once in the room and Olivia finally got to see the brutal wounds on his shoulder. As she touched it, he winced.
"El, you've lost a lot of blood; I need to call a bus." Olivia screamed as she heard the dog scratching the other side of the door with its claws. "Elliot!"
"That's one helluva husky, Liv. He'll get bored. Make sure you call Animal Control, too." Olivia nodded her head while she dispatched 911 and Animal Control to Sam's apartment.
"I hope they get here very soon. I shot that monster 3 times and it didn't die, Elliot. What do you make of that?"
"Resilience? I guess he has a strong will to live." A thud from the other side of the door startled both of them. The sound of wood breaking scared them even more. Elliot reached for his gun, but discovered the holster empty.

"Damn!" he cried. "My gun must've fallen out when that dog tackled me to the ground."

"My gun's pretty much empty. I nearly emptied a full round on it. Is there something here we can use to defend ourselves until Animal Control arrives?" As Elliot began to sit up, Olivia placed her hands on his body.
"Stay there and don't move. If you move, you'll make your injuries worse, okay?" Elliot shook his head.

"Be careful, Liv." Olivia searched the room for anything useful, but was unsuccessful. Elliot looked to his right and underneath the bed he was laying next to was a dagger. He crawled over and reached with his hand to grab it. The dagger was very dusty, but beautiful. Underneath the coat of dust revealed a hilt adorned with jewels and silver.

Another crack in the door allowed the vicious dog to break through and its target was Elliot.

"Elliot!" Olivia cried as she witnessed the scene between her partner and the dog. Elliot grasped the knife tightly in his hand and thrust it into the wild dog's chest. It backed away from him, hissed, and ran out the room quickly. A medic followed by an animal control officer suddenly barged into the room.

"We received a call about a wild dog and an officer down. Where is he?" the officer asked. Elliot's vision became hazy and his body was on fire.
"The dog left the room quickly… didn't you see him?" he whispered.
"We didn't see a dog. Are you okay, sir?" the medic asked while applying a bandage to the wound on Elliot's shoulder. Elliot nodded his head but passed out. "Sir, hang on!" Elliot was led out of Sam's apartment on a gurney and Olivia rode in the ambulance with him on the way to the hospital. She called Cragen and informed him what happened earlier.

Yeah, it's weird and I think you know where this is headed. Reviews are appreciated! :)
