I close my seat belt as the sign pings on overhead, the plane beginning its decent. Only now do I fully think about how big a step I'm taking, maybe to big but I also feel excited, partly at meeting the man I've been talking to all year and partly because for the next week I'll be living as a puppy my biggest fantasy, one I've had for so long that I can’t remember never having it, finally lived out, I can't wait to get off the plane. 

Over the last year I've been chatting with my owner for the week, both in messages and video calls. We spent countless hours discussing our lives, our hobbies, our fantasies, our shared love of puppyplay, we even talked about my most extreme fantasy when he mentioned being a surgeon. We spent hours planning this meeting, for the next week I'll be kept naked, collared, on all fours, not allowed to speak except for dog noises, sleep in a dog bed and cage, eat and drink out of bowls and go to the toilet outside or in a litter box, to make things more interesting my owner will not speak to me in English while I'm a puppy, meaning I'll be unable to understand anything he says and have to learn key words and instructions, just like a real dog would, the idea excites me. 

The plane bounces slightly as it lands and I get up as soon as the sign pings off, only having a small backpack I manage to get off the plane quickly and eagerly pass through the security into the airport, not stopping at baggage due to not bringing anything except the change of clothes for my trip home. 

I step outside and see my owner for the week and move towards him.

"How was your flight?" I smile unable to hold in my excitement at finally meeting him.

"It was a bit bumpy but not bad thanks." He smiles.

"Shall we get back to mine and start or do you want to do anything before we start?" Eager to begin my week living my dream fantasy I feel to impatient to want to explore the sights, maybe next time.

"I'm happy to go straight to yours and get started on our plans for the week, unless you have anything you want to show me first." He smiles happily.

"Alright then my puppy, let's get you to your new home." I follow him to his car and climb in as he opens the door for me and we drive off to his home. 

I'm guided in through the front door and brought to the living room, where I see a dog bed and cage, the bed for nights and the cage for when he is out and I'm unsupervised. 

"Well puppy remove your clothes and place them in your bag." I smile, no messing around, just getting started exactly how it should be, anything else at this point would have been frustrating. I quickly remove my clothes, not bothered about him seeing me naked, I'm his puppy, dogs don't wear clothes and aren't bothered by being exposed and naked. I stuff them uncaringly into my backpack and watch as my owner takes it from me.

"I'll store this somewhere safe. Stay here." I stand still, like a good boy, and patiently wait for my owner to return, already enjoying being told to stay. He returns holding several items.

"On your knees and sit like a good boy." I do as I'm told and sit, my legs tucked under my ass and my arms supporting me as I lean forward. I look up lovingly at my owner as he bends down and wraps a collar around my neck and locks it on, the leather and the dangling tag marking me as his pet for the week, a feeling of pride and value flowing over me, finally being collared, having an owner who wants me, loves me, values me, cares for me, enough to mark me as theirs. I can’t help but pant slightly in joy and excitement.

"Paw." I raise my right arm, keeping my hand limp, almost without thinking, and don't resist as my hand is slipped into a fingerless paw shaped glove and locked around my wrist, nor do I make any attempt to resist as the same is done to my other hand, leaving them completely useless and unable to grip things, just like a real dog. 

"Stand." I do as I'm told and rise to all fours, I let out a slight pant as I feel his hand stroke my head and back, happy to finally feel his hand running down my body, to feel him reward me for my good behaviour. I feel his hands feel around my crotch, as he slides my balls through a metal ring and then slides a small tube over my semi erect cock, crushing it slightly as he clicks the chastity cage shut, locking my cock away, preventing me from misbehaving over the week and humping his leg or the furniture, in my extreme fantasies I'd be fixed just like any other dog but for now this will work as a temporary solution. I let out a slight whimper as I feel my cock testing its new home for the week, straining against the metal surrounding it, my owner giving me a reassuring smile and stroking me, the feeling calming me down, reminding me that everything is alright. 

I stay still as I feel leather restraints wrap and lock around my ankles, chains attached to both link my ankles to my chastity cage, preventing me from standing on two legs like a human, forcing me to remain on all fours like the animal I now am and will be for a week.

"There, all finished. Remember puppy, I will no longer speak in English, you must listen and learn commands, and any attempts to speak human or misbehave will be punished with your shock collar. Understand?" I feel excited as we finally begin our week together.

"Woof!" I feel a stroke on my head as my owner says something in their native language, one I don't know, I have never been good at languages and deliberately haven’t learnt my owners to enhance the experience, but his voice sounds calming to me.

I hear the voice of my owner and recognise my name, over the last few days I've learnt many words, my new name for one, food, breakfast and dinner, toilet, good and bad boy, simple commands, come, sit, lay down, roll over, fetch, bed, cage, beg, even a few more complex words, like suck, lick, raise my ass, all of which my owner loves making me do, having me suck his cock every morning, enjoying having me lick his ass and feet regularly, and fucking my ass at least once a day, causing me to pant and howl in pleasure. I still don't understand the rest of his language, only really focusing on words that directly relate to me, I have no need to know what he is saying when talking to others on the phone or even when talking to me about things, I only need to know when he gives me a command and to obey it like a good boy. 

Hearing my name again followed by come I rise to all fours, feeling the chains tug at my chastity as I stretch, and make my way towards my owner. Reaching him he smiles and strokes my head lovingly, which I enjoy, I always like being stroked, it will be something I miss when the week ends, part of me wishing that it wouldn’t. I watch as my owner says something, he seems a bit sad and I rub my body against him to try and tell him not to be sad as I'm here. He holds up his phone and I look at it confused for a moment before reading the date and time, the information taking a moment to process in my mind, for the last week dates and times have been a meaningless concept. Today is the day I go home, I now understand why my owner is sad and let out a small sad whine, part of me doesn't want this to end. Wait, my flight is in an hour, why am I not getting ready to leave, I should be going to the airport by now. I look up, my panic clear on my face but I still don't speak, I have done so a couple of times over the week, my owner quickly punishing me and training me not to with painful shocks from my collar conditioning me to behave. My owner smiles and says something that I can't understand and stroking me lovingly, bringing their face close to mine.

"I have decided to keep you here with me puppy." What! He can't! I feel helpless as I begin to realise how trapped I am, I'm naked, my hands completely useless, trapped on all fours, no passport, unable to speak the language or understand it, I'm truly helpless and at the mercy of my owner, just like a real pet dog would be, my fantasy becoming even more real than it had been for the whole week. 

As I sit in shock and frozen in panic I feel my owners hand gently stroke my body and his words fill my ears as he tries to reassure me that everything will be fine. Maybe everything will be fine, I did enjoy my week here, so much that I lost track of time, part of me even wanted to stay, as he continues to stroke me I slowly calm and start to pant, fully embracing the puppy inside, my mind giving in and admitting defeat. 

Epilogue: 

I excitedly chase my ball, picking it up in my mouth, my modified body racing back on all fours. My owner taking the ball from my mouth and calling me a good boy, before holding it up and throwing it yelling fetch as he does, I happily turn and chase after it, my body moving fast on all fours. 

Over the years my owner has been kind to me and looked after me lovingly, I never had anything to worry about when they said they'd keep me here as their puppy, I've loved every minute of my life with them. The only scary part was waking up once after my modifications, waking to find that my feet and fingers where gone and my balls where removed was frightening but my owner was there to comfort and reassure me and help me learn to live without them. Not that I miss them, I have no need for them, my owner looks after me and gives me everything that I need, food, water, a warm bed, plenty of love and attention,  plays with me, even gives me treats, I love being with my owner. 

I return and pant happily and tiredly as I drop the ball, my owner lovingly smiling down at me and stroking me, his pleasant sounding words still unknown to me as he speaks, my mind not even trying to learn, lost in my puppy state, unable to ever leave it, blissfully unaware and happy, just like any well looked after animal.
