My Beloved Dog is the Strongest in Another World

-My Beloved Dog Became Big-

“… Phew… That was another hard day.”

At midnight when the date was about to change, I was finally finishing my work and ready to return home.
I don’t remember returning on time recently.
It’s been two years since I started this job.
I don’t have any days off, and I think it’s a completely black workplace with constant overtime.
However, I haven’t had time to look for another job, so I’m continuing my current one.

“Ah…I feel a little dizzy.”

Before, when I was working continuously for 3 months without a break, I once collapsed at home.
At that time, I woke up immediately, but I took a day off from work and went to the hospital because I thought this was dangerous.
But when I went to work the next day, my superiors were angry and my coworkers gave me dirty looks.
While this wasn’t as bad as that time, my walking was a little strange.
I wasn’t drinking.
I have just reached adulthood, and while I have drunk alcohol, I haven’t drunk enough so that it seems delicious.
The boss once took me to a drinking party on a day when there was little overtime, and I remember being forced to drink a lot of beer and having to rush to the bathroom many times.

“What is with…this workplace.”

While mumbling to myself, I walked from the nearest station to my home.

“Oh, I should stop at the convenience store.
I haven’t eaten anything today… And I can buy something for her and go home.”

I entered a convenience store on the way to my house and bought a lunch box and sausages, remembering that I hadn’t eaten anything today.
She must always feel lonely, and so sometimes I want to buy her favorite food and make her happy.
I left the convenience store and headed home again at a slightly odd pace.
I arrived at the apartment after walking for about 10 minutes, and took out the key from my pocket in front of the nameplate that read Takumi Hirooka, and opened the door.

“I’m home.”

I opened the door and went inside while calling out to her.
I could hear the sound of scratching behind the door, at the back of the corridor leading from the entrance.

“Good, good.
You’re lively today.
I’ll open it now, so wait!”

I take off my shoes, go up to the corridor, stand in front of the door and open it.
As soon as the door was opened, a white object rushed out from inside.

“Kuuun… Kuuun…”
“Haha, okay-okay.
Were you a good girl?”

It was Leo, a Maltese, that jumped at me.
Our first encounter was when I found her as a puppy in a cardboard box that was thrown away a few years ago.
As a student at that time, I had just started living alone, but thanks to Leo, I wasn’t lonely.
When I picked her up, I called her Leo without thinking, but later realized that she was a female.
That was a good memory.
I’m sorry Leo, I gave you such a name in spite of being a girl.

“See, I bought your favorite sausage today!”
“Kuun… Wuff-wuff.”

When I showed the sausage, the tail that had been wagging a while ago began to wag even more violently.
She put her nose close to the sausage and was about to open her mouth and bite into it.
“Hahaha.
Wait, wait.
You can’t eat it like this.
…Here, you have to take it out of the wrapper first.”
“Wu
