I had to admit, Puro definitely wasn't what I expected to find. I had thought that the mysterious helper who had left all those notes for me to follow was a human like me; instead, it was a black latex wolf that somehow retained intelligence and was fascinated by humans. What's more, it wanted to be my friend! I initially felt suspicious—even frightened—but in the end, Puro was just too nice, and too cute, to be a threat. He even told me about a keycard in a pile of books nearby that I could use to get out of the library; I thanked him and began carefully searching through the pile.

“Should I... I want this, but... I can't...”

I whipped around to see Puro standing behind me; I clearly startled him with how fast I turned, because he immediately floofed up.

“AHH! Human, p-please don't turn around so fast... Oh, uh, did Human find the keycard yet?”

Good lord, he's adorable, I thought. As much trepidation as I had when I met him a few minutes ago, I found it difficult to be afraid of Puro—not just because of how cute and polite he was, but because of how genuinely helpful he'd been. In any case, I shook my head in the negative and went back to searching. Fortunately, after a few more seconds, I managed to locate the prize I sought—the keycard that would allow me to escape the library and take another step towards escaping this strange and awful deathtrap of a facility. Unfortunately, the keycard had one little problem attached to it.

“Is that a collar? Odd,” Puro remarked with a head tilt. “it smells kind of funny, too. The same as Human's shorts... I wonder if they're made of the same thing? Hmm... oh well. It's probably nothing to worry about.”

I shrugged; Puro likely knew more than me about this sort of thing, so if he said it was safe I decided it probably was.

The black wolf paused for a few moments, then gave me a sad look. “Anyway... it should work, but... well, there's danger that way. I hate to see Human leave... I've been waiting so long, and I've been so alone... Human is my first-ever friend. But all the same, I hope Human succeeds. If Human needs any more help, just come back here!”

I smiled at my new friend and thanked him for his help; I almost felt bad leaving him alone, but I had to see this through. After promising to come back if I needed his aid—something that made him practically light up with joy—I left the room, somehow managing to resist the urge to hug him. As I made my way through the library toward the locked door, I started to worry about potentially dropping the keycard in an ambush; after all, I had no pockets, and with the collar attached it wouldn't just fit in the shorts as it was. I tried and tried to remove the keycard from the collar, but after a few fruitless and frustrating minutes I begrudgingly decided that it would be simpler just to put the collar around my neck until I reached the door. It managed to fit me well enough—comfortably, even—so I continued on my way, not even giving it a second thought.

After some careful sneaking to avoid any potential threats, I finally made my way to the door, only to find that the collar was somehow stuck on my neck and would not unbuckle. Biting down in frustration, I bent over to allow myself to insert the keycard into the slot, figuring I could figure out a way to remove the collar later. As I continued through the door, I noticed that the screens on the wall lit up, and prepared myself for yet another annoying monologue from my mysterious captor. Fortunately, it appeared that my host was experiencing technical difficulties once again, as all that managed to get through were quiet whisperings and mutterings that only barely cut through the intense static. I did my best to ignore it and continued on my way as the static and voices faded into the background. After a few minutes of walking, I started to notice a tingling sensation around my neck, but I suddenly had the feeling that it wasn't anything to worry about. In fact, I understood that it was a pleasant feeling, one that I should accept as being perfectly normal. I continued on through a few more rooms, the voices and static a constant companion in my head, until I came across a long hallway filled with bookshelves; in the middle of the hallway, staring straight at me, was a massive white fox. For a moment, I stood in fear, but instead of attacking, the fox yipped and fled from me. Why would it run? This made no sense.

“...od bo... owl an... ase.”

I growled for a moment as a strange thought went through my mind; suddenly, I knew what was wrong with the situation. That fox was mean! Very mean! I had to chase him and show him who was boss! I rushed after the latex beast; as I did, the static cleared up and the voice was louder, but I didn't have time to pay attention. I had to chase that fox! As I ran, I realized I wasn't fast enough. Something was getting in the way.

“...ood boys don... ed... rts. Good bo... llar.”

Yes, my shorts. I needed to get rid of them. It was fine, I had a collar. That was enough. I felt something spreading across my body, and my face felt funny, and so did my butt, but that was okay. Everything was as it was supposed to be. I just needed to focus on my prey. But I still wasn't fast enough... Then I heard the voice from the screens. It was loud enough to make out clearly this time, and it told me what I needed to know.

“Good boy! Good boys have four legs, not two. Good boys run on all fours.”

Yes, that was right. I dropped down on all fours, feeling a sense of rightness as I did so, and continued running. This was so much faster and better than two legs! I was glad that the voice was there to help me. It was a nice voice.

“Good boy! Chase. Good boys chase. Bark, good boy. Bark and chase. Good boy!”

I yipped happily, knowing I was doing what I was supposed to. Unfortunately, I lost track of the fox after a while; I started growling in anger. It escaped! Stupid fox!

“It's okay, good boy. You just need your friends. They can help you, good boy.”

The voice was nice. I liked it. It made sense. It called me a good boy, which made me happy. But who were my friends, and where were they?

“Good boys have good noses. Use your nose, good boy.”

Yes, that made sense. I sniffed the air; a nice, familiar scent alerted me to a large number of dogs in a nearby room. Those must be my friends! I barged through the door and saw a whole pack of brown-and-white furred latex dogs; I briefly thought I should be afraid of them, but then the voice spoke again.

“Good boy! You found your friends!”
Yes, these were friends. They had brown fur like me. They had tails and snouts and wet black noses like me. The voice was so smart!

“Bark, good boy.”

I barked, and my friends happily barked back, which made me bark again! I forgot what I was doing before, but it didn't matter, because my friends were here and we could play.

“Good boy! Bark more, play with your friends. Good boys bark and play.”

I barked and played, because I was a good boy. After a while, though, things calmed down, and my friends yawned.

“Good boy! But look, they're sleepy now. Good boys are sleepy when their friends are sleepy.”

Yes, I was sleepy just like my friends were. I was a good boy.

“Good boy. Snuggle up with your pack. You're so tired, good boy.”

I did as the smart and nice voice told me, laying down and snuggling up to the other dogs and letting out a deep yawn, stretching my forepaws out in front of me.

“Good boy. So tired.”

I was a good boy. And I was so tired.

“Good boy. So happy and calm.”

I was a good boy. I was happy and calm.

“Very good boy. You're where you belong.”

I was a very good boy. I was where I belonged. I smiled and huffed as my eyes fluttered shut, the nice and friendly voice telling me nice and friendly things as I drifted off to sleep along with the rest of my pack.

“Goodnight, good boy...”
