Scott and Gary were the best of friends. They used to lived next door to one another, but one day that all changed. Scott and Gary shared a lot in common even the same birthday. They called each other brother and they meant it. Gary was an only child and Scott’s two older sisters had no time for him. Scott’s parents were good people, but always so busy with work. In fact that’s where the problem started. His dad got a big promotion and informed the family they were moving to Arizona. They would be moving the day after Scott’s sixteenth birthday.
“That sucks,” Gary said when he heard the news. “It’s just not fair.”
“Yeah, I don’t want to go.” Scott kicked a rock across the pavement as the two teens walked to school. “They never care what I want. I hate them.” This of course was not true, but he had to let his anger out.
“This whole day sucks. I have a test in History and I find out you are moving half way across the country. Could this day get any worse?” Gary felt like crying, but he was at the age where he thought it was no longer allowed. All he could manage to do is throw his backpack to the ground and make a strangled yell of rage. “Aaaarahh! I can’t take it. This just sucks, man.” He let out a little more of his frustration by kicking his backpack, which honestly didn’t satisfy him at all.
That afternoon the two teens took the long way home, which took them past a several stores. They were passing a pet shop when Gary said, “You know, my parents told me I could get a dog for my birthday.”
Scott laughed and responded, “Maybe we could convince them I was a dog and I could stay here with you.”
“That’s not a bad idea,” Gary said excitedly.
Scott looked at his friend as if he were from Mars. “What?”
“No, I don’t mean you could become a dog. What if I could convince my parents that you should live with us? You have two more years of school. Maybe your parents would let you stay so you don’t have to switch schools?”
It is a big responsibility to have a dog; it is a bigger responsibility to raise someone else’s child. Gary’s parents said they just didn’t know if it would work. Scott’s parents wouldn’t even consider the idea.
The next day the teens went in to the pet shop on their way home from school. Gary was still in a bad mood, but couldn’t hide his excitement as they looked at the puppies. One of the employees carried out a small gray and white husky pup for the boys to play with. They laughed and for a moment forgot their worries.
“I wish I could be as happy as that puppy,” Scott said as the two of them exited the pet shop. “Playing with him was great, but really… I’d trade everything to switch places with him.”
A week later Gary asked, “So what are you getting me for my birthday.”
“I don’t know. I hadn’t really thought of it yet.”
Gary grinned mischievously. “Well it had better be good, because I found the perfect gift for you on the internet.”
Two weeks passed and Scott couldn’t get Gary to tell him what the present was. Scott saved up what little money he had and bought Gary some dog toys. It was an odd birthday present, but there was no way he was going to find a better present than what Gary’s parents were getting him. The two teens had been stopping off at the pet shop almost every day to play with the husky, but a few days before their birthday it was gone.
“Yeah,” the employee replied. “A cute little girl and her parents took him home last night. It might be a month or more before we get another husky in. Is there another dog you’d like to see?”
“No, we’re good,” Gary said. Scott was surprised when his friend didn’t seem the least bit disappointed. “My parents know I want a husky. I’m sure they’ll look around until they find one.”
When their birthday arrived it was bittersweet. Scott’s parents bought him a tent and suggested he and Gary camp out in the back yard one last time before they have to say goodbye. They had been camping in the back yard since they were eight years old. Scott had thought the tent back then was the best birthday present ever. He was happy for the new tent as the old one really needed to be thrown out, but at the same time he was saddened that the new one would be used to mark the dismal occasion of his moving away.
Gary’s opened a small package from his parents. Inside there was a collar and leash. There was also a picture of a fully grown husky surrounded by little pink pups, obviously just born. His parents told Gary they were in contact with a breeder and they promised to take him to pick out his own dog as soon as they were ready to be weaned.
He then opened Scott’s present and laughed. “I’m sure my little pup will love them.”
There was one last present. A large one from Gary to Scott, but Gary said he’d have to wait until tonight to open it.
That night under the glow of a lantern the two teens sat in the new tent. Gary pointed to the present and said, “Happy Birthday, Scott.”
Scott ripped the paper and opened the cardboard box to find white and gray fur. He looked at his friend questioningly as he pulled out a husky costume.
“Isn’t it great? Remember how you said you’d give anything to switch places with that pup? Well I can’t make that wish come true, but just for tonight you can be my dog. And anytime while you are in Arizona you can look at it and remember me.”
Scott laughed. “You have the craziest ideas some times.” He held up the costume to his body and noticed the proportions seemed off. “You sure this will fit me.”
“Yeah, we’re about the same size, so I had my mom measure me. Go ahead and put it on. It’s called a quad suit. You’ll actually be walking on all fours. There’s some kind of stilt in the front legs to make it look realistic. Oh and once I zip you up… well, you won’t be able to get out without my help. You okay with that?”
“I trust you Gary.” Scott stepped into the furry dog suit, and struggled to get himself into the right position.
“Here, let me help,” Gary offered. Before long Scott was zipped up and standing on all fours in the tent.
“This feels odd.” Scott turned around a few times to try and see his tail. He noticed the head’s jaw opened and closed as he moved his mouth. “This is amazing. Where did you get it?”
“I found a place on the internet. My parents are going to kill me when they find out I spent my college savings on it, but seeing you there is worth every penny. Oh, and remember you are a dog. Dog’s can’t talk.”
“Oh, sorry. I mean, woof? Hold on, let me get this right.” Scott then barked and felt happier than he had in a long time.
“That’s the spirit, boy.” Gary patted Scott on the head. “Tonight we’ll imagine some magic really turned you into a dog and you will get to live with me. You’d like that, right boy?”
Scott barked again and pranced around. This was a lot more fun than sitting in the tent brooding about their impending separation.
“Do you want to play fetch? Do you, do you? Come on boy, let’s play fetch.” Gary picked up one of the dog toys Scott had given him earlier in the day.
Scott laughed. “I didn’t think I’d be playing with the present I bought you.”
“Bad dog.” Greg said with a grin, “I said no talking.”
Scott played along and whimpered apologetically.
“That’s okay. You’re a good dog aren’t you?” Gary patted him on the head again.
Scott knew it was a little odd pretending to be a dog, but all the same he was having fun and decided to play the role as best as he could. He barked and tried his best to wag his tail.
Gary laughed, unzipped the tent and tossed the rubber bone across the yard. “Go get it boy.”
Scott cocked his head to the side and gave a worried whimper.
“Go ahead. Oh don’t worry. Who’s going to be looking out of their windows this time of night? And who cares. If you are enjoying being a dog then be a dog.”
Scott barked and ran off after the bone. He was amazed at how well he could run considering it was his first time using hand stilts. He got to the bone and opened his new mouth. After a few failed attempts he managed to pick the bone up and pranced back to Gary. They played fetch until his arms and legs were tired. Scott turned around a few times and sat down.
Gary ran his hand down the dogs back. “You know in this light, I’d swear you were a real dog.”
Scott wagged his tail at the thought of being a real dog.
“How are you doing that?” asked Gary.
Scott barked and tilted his head in confusion.
“How are you wagging your tail?”
That was a silly question. Scott was a dog and dogs wag their tails. He let his tongue hang from his mouth and began to pant.
“Scott, talk to me. How are you doing that.”
Scott just cocked his head and barked. He was tired of being in the tent. He stood up on all fours, walked over to the leash and whimpered.
“No I’m not taking you for a walk. Scott you are beginning to scare me.”
Scott picked up the leash and dropped it at Gary’s feet.
“Stop that. I’m getting you out of that costume.” Gary unzipped his friend and backed away in surprise.
Scott climbed out of the dog suit and looked down at his skin which was covered with white and gray fur. He wagged his tail with delight. “How are you doing this?” He took off his shirt and rubbed his paws all over his furry body. His shorts seemed too big for his waist and he grabbed them before his wagging tail pushed them down any further.
“I didn’t do this. I mean, I thought about you being my dog ever since that day in the pet shop, but how could I be doing this to you?” Gary reached out and touched Scott’s shoulder, feeling the fur. “This is too weird.”
“Gary I’m going to ask you a question. I feel like I’m right on the edge. If I pull back I’ll be human again. If I let myself go I just know I’m going to be a dog forever. And honestly, I’m happier than I’ve ever been just thinking about that. But I have to know one thing. Gary, do you want me to stay with you?”
Gary looked up and down at his fur covered friend. “But you’d be giving up so much. What if you can’t be human again?”
“I don’t care about that. I just want to know if you want me to stay.”
“But what about your parents and your sisters?” Gary asked.
“Gary, do you want me to be your dog?”
Gary looked around the tent and finally said, “Yes. I’ve been thinking about it every day for a month. I’d take such good care of you and I’d be sure to find a place to live at college that allows pets. I never want you to leave and I’ll never leave you.” Tears were in Gary’s eyes.
“Then all I have to say is this is the best birthday present ever.” Scott barked and immediately began shrinking. As he got smaller his proportions became more dog-like. Soon he looked exactly like the puppy they had played with in the pet shop. Gary watched in amazement as the costume, box, the toy bone and even the tent around them disappeared. Whatever magic caused this transformation wasn’t a cruel one. His parent’s wouldn’t mourn a child who had vanished in the night. They would move on never knowing they had raised such a caring son who would sacrifice everything rather than cause his friend pain. Gary would forever remember his friend and his choice to become a dog rather than leave, but the world forgot about Scott.
Gary’s parents forgave him for spending his college tuition on a dog rather than waiting for the breeder’s pups to be ready. They too loved Scott, even though they thought it was an odd name for a dog. Scott grew and was well cared for and happy. He watched his friend grow and eventually was the protective “older brother” to Greg’s children. He lived far beyond the lifespan of a husky. When anyone asked Greg his secret for having such a healthy, long lived dog, he would always answer, “Brotherly love.”
