|Oh well wasn't this just lovely!
First read: gorgeous storyline, lovely development, surprises, details, and the ability to put a smile on my face. Everything I want from a short piece like this.
You never actually reveal what made that day different, what the offence exactly was, that he committed. I'd like to know that, but if this was a conscious decision, I suppose it makes sense and adds to the suspense you manage to create. Even if it can be omitted at first, could it be fit in later? The woman coming home with him does not appear to be it, at least that is how I read it at first.
At a second read, she becomes more obvious. But still... how does the pug know in the morning? How is the deceit first established and noticed? That part feels somewhat inconclusive. But maybe I'm reading it wrong.
Like I said, I like your work a lot. Keep it up and feel free to let me know if I've read it wrong.
