I Wish by William Marsland.

My little sister liked swimming with the fishes,
though we have none down the well.
She loved to really sing out loud,
I heard it in her yell.

My little sister always had her puppy by her side,
she never let me play with it, told mommy that I lied.
Now they both swim with the non-existent fishes
and I have my own little puppy.

Nice title LOL

Hmm... the only thing I would maybe change is that ending line. It breaks the rhythm of the rest of your poem,, and I think there's a way you can say you "inherited" the puppy but in a funnier maybe slightly tangential way.

Quite a black comedy piece

the puppy went to the same place the little girl did

but i see what you mean about the last line. it does feel a little forced.

Ha!

It's not bad though. A little tweaking will do wonders
