Falsely Accused

I came home to a puddle on my bathroom floor.
I have a mutt. (I will attempt to add a photo- but, I’m still new at this) - a picture being worth a thousand “OH! Is that a DOG?” comments. (And yes, it IS a dog).
He’s 15 and a half years old now. A rather nice companion. He was mine originally - having traveled up to Lancaster in a terrible storm to pick him up…and then my Mom moved in - and he was ALL about Gramma. Years later, after my Mom passed away, Toby (Tobias until Mom moved in), spent 2 weeks grieving in her room (I’m going on 5 years 2 months myself) - in her rocking chair, no less - before he ventured out to my room , and has been mine ever since. Everyone in my family hates him. Or at least, dislikes them to the best of their ability. (My daughter, with a fearful expression on her face said “He’s going to outlive us all Mom” - fearing of course that she will inherit him.) I like him, aside from the occasional chill up my spine when I walk him. (I read a passage in a book a few years ago “Young women walking small children, old women walking small dogs” and it made me cringe). Altho, only my grand daughters think I am old- it’s all relative- no one my age thinks I’m old.
But, aside from a few ‘political statements’ over the last few years the mutt hasn’t made any puddles on the floor - especially in the middle of the floor - (he’s a boy- I’ll have to check the walls) for years.
But, I did, failing to take any DNA samples- and purely on circumstantial evidence alone- accuse him.
Until I felt a drop on my head and realized it was the new sprinkler system management installed. I have notified the landlord - but, felt silly apologizing to a dog- so, I just gave him and extra walk around the block and doggie treat. Mutts are so forgiving.
