Chapter Four

I promised Aunt Cass that I would go to my classes this afternoon but I think that she understood the need to take Tadashi to see a vet. For just a little while, I'll have to pretend that he's a regular dog because he has to be looked at by the vet. I'm not letting anything happen to him and I'd rather a professional put a tracking chip under his fur than mess up upon doing it.

I hold him on my lap as we sit in the waiting room. Fortunately, it's not too busy right now. I gently pet him as he looks around nervously. There are some animals here and he's already seemed to interact with another dog. I pull him closer, "It's going to be okay," I tell him in case he's frightened about seeing the doctor, "and I'll be right beside you." I turn him gently to look at me before putting my hand out for a fist bump that he returns.

"Hiro Hamada," the vet calls out and I stand, still holding Tadashi close to me, "It's your turn."

I pull Tadashi closer before taking him to the room and I see all the needles and equipment, I look up at a picture that Tadashi is staring at. It's discussing the health benefits to spaying and neutering your pets. I'm not going to castrate my big brother, I don't feel comfortable with that.

"So, this is Dashi," the vet smiles, "Can you put him down for me. He's what…three months old, four months?"

I blink. First of all, why doesn't this vet know just by looking at him how old he is. Second, is he that young a puppy. He should be older than that, he's the older one of the two of us but I guess an older dog would be harder to take care of and greatly reduce his life expectancy.

"I'm…" I say nervously, "I'm not sure. I adopted him recently. I just need you to run tests on him and insert that that tracker thing so that if he gets lost I can find him. Please be as gentle but as thorough as possible. He's family to me," I tell them and the vet nods. I wonder how many people actually will say that to him. It shows that he isn't the first one to have heard it. "Oh and no neutering. Please don't cut anything off without my permission."

"We'll do what we can," the vet tells me and he's acting as if I'm worrying too much, concerned too much about this. Never. I can never be too concerned about my brother.

…

…

I know that Hiro has very good reason to worry but I trust him, I trust the vet as well. I mean, I have to accept the fact that I'm a dog but at least I get to accept the fact that Hiro and Aunt Cass see me as a guy who has been trapped in the body of a dog. Hiro is getting too stressed worried about me. It'll be okay. I'm thankful to him for allowing me to keep my manhood.

"First we'll do some blood tests and then check out his body, his flexibility, his tail, his teeth," the vet says and I look to Hiro to see him nodding uneasily. I know that I have to act as a dog. I don't have the luxury of letting the vet know the truth.

"Can I hold him?" Hiro asks as the man gets the needle out. I just have to get through this, it's for my own good and the fake Tadashi has hurt me worse than any needle can. The vet nods and Hiro brings me to his chest protectively. I flinch as the first needle gets put in my leg and Hiro pulls me close as the doctor gets three tubes of my blood.

Is it over? Hiro gently brushes the fur on my head back. "It's over," he tells me and I feel myself fall limp from relief. Hiro gets nervous and so I look up at him and bark. I know that there are several other tests and tasks I need to complete but we'll go slowly and soon my checkup will be over.

"We'll want to put him to sleep for the next part. Just a slight bit of anesthetic," the vet says and I see Hiro panic again. I want to tell him that it's okay, that I trust them but he has a right to worry about me. I just wish that I could help him as well.

….

….

Tadashi is beginning to wake up from where they put him under with a tranquilizer. I was really worried about him and them doing it but they allowed me to stay with him the entire time. I don't care if they think I'm crazy. I've already lost my big brother once and I'm not going to go through that again. They told me that he's in perfect health and to help him with his baths and teeth and to pay attention to his food. Maybe he'll forgive me if I balance the dog food that I'm supposed to be feeding him with leftovers and table scraps. He shouldn't be eating human food apparently.

I put a hand where he has his new tracking chip, it's tiny but it works and I'm able to see where he is on my phone and even call a number for help if he can't be found. As his eyes open and he sleepily looks at me, I reach out and ruffle the fur on his head and scratch him behind the ear.

"You have a good sleep, little guy," I tease and he rolls his eyes but then nods.

I pull him up and hold him to my chest before seeing him look down to make sure his balls are still there. Again, I couldn't do anything like that to him. "I've already paid the bill, we can go home and you can spend the rest of the day with Aunt Cass, okay?" I ask and he yawns before leaning in closer to my chest. I walk out of the vet's. Maybe we could get a treat or look for dog food or something. However, as I walk forwards, I feel a hand on my back.

I turn and my body feels an ice cold chill as I see my brother looking back at me. He looks more like a business man than his usual casual look but I know it isn't him. I pull the real Tadashi closer as I see the fake spot him and reach out to touch him. I pull him away.

"Why are you here?" I ask as I feel the pain of watching my brother look so menacing and scary. "You can't have the dog."

"The dog is worthless to me," he says with cold and cruel eyes and I hear the real Tadashi whimper, I hold him tight but see the fake Tadashi reach out as if to strike him. I pull back, giving a pained look at seeing someone in his body doing that to me. "He's served his purpose, he just needs to know how to be disciplined."

I pull the puppy Tadashi closer to me and glare at the man who has been abusive to him. "You don't want to mess with me," I tell him. "You really don't want to mess with me and I swear, you try to hit him again and I'll make you regret it. I'm not going to stand by and watch you take a crap on everything that Tadashi has done in that body. Find somebody else's body to use or stop being a creep and find your own."

I see him reach out for me and I notice him reaching for a knife. The puppy Tadashi jumps from my arms and bites his wrist hard. I see the man turn back to the knife and I pull it from his hands. He kicks Tadashi hard and the small puppy rolls onto his side. I crouch down next to him and see the man walk off, swearing about his wrist.

"You can't do that anymore," I whisper as I pick him up and gently press him to me. "You can't protect me anymore not until you get bigger. I can't lose you again," I tell him and he takes labored breaths before sinking his face into my chest. I sigh. I hate how things are but I'm not going to let that guy go free. Still, some things, like puppy Tadashi are worth so much more. I really can't bear to lose him again.

…..

…..

As I lay on my side where he's kicked me and the pain is horrific, I try to search for the knife. He just tried to pull a knife on my younger brother. Even though I'm in this form, I couldn't let him hurt him, I was trusted by our parents to look out for him and if that means doing it from this body then so be it. I wanted Hiro to be proud of me.

As he walks away, I find more trouble breathing but at least he's leaving. Hiro's fingers are lightly resting on my belly, "You can't do that anymore," Hiro tells me and I look at him sadly. I knew it was risky but being a big brother means that you have to take risks.

He picks me up gently and presses me to his warm chest, "You can't protect me anymore," he comments and as hard as it is to let it sink in, it's true. "Not until you get bigger. I can't lose you again." I try to breathe. I don't want to admit how scared I am, Hiro has always looked up to me and now he probably sees me as only a puppy. I hope I'm not as dispensable as a puppy.

He holds me close, gently petting me. I hate seeing my own body do that but I've become used to it. I don't think that I've become used to him doing that to my little brother though. I close my eyes and he holds me as you would carrying a baby, rocking me gently. I used to do that when I was a kid, holding Hiro. It's so strange to see this role-reversal.

I wake up as Hiro takes me to the garage and I look around. I wonder why he's brought me here," I bark at him before noticing that on his computer he has something labelled Tadashi. I tilt my head wondering what kind of stuff it is. "Stay here, okay?" Hiro asks as he sets me down on the chair and I look after him. I'm supposed to be the one taking care of him and not the other way around.

I try to see what's going on but it's hard and each time Hiro sees me move he tells me just to stay and get comfortable. I'm an inventor, a researcher or at least I was as a human. I developed a health care companion, despite being in this body I'm still intelligent, I just can't make that intelligence known.

I sigh as I sit down and then look up to see that Baymax is watching over me. Funny.

"I am sensing a slight bruising to the side giving a mild to moderate pain. The dog has also been sedated recently but all organs seem to be working well." Baymax puts out his robotic hand to me and starts petting me, he heats his hand a little. "Good boy. Good boy," he repeats. "My new dog health care card says that a canine likes to be praised."

"Yeah," Hiro smiles, "He's amazing. Still my personal hero," he says despite the way that I'm looking at him. He watches as Baymax touches me and I yawn. I curl up in the chair and start to go to sleep, just as I'm about to succumb completely to the sleep, I feel a blanket being tucked around me.

"Just get some rest," Hiro tells me as he pets the back of my neck. "I'll wake you before I have to leave."
