"My life as a dog." There was nothing suspicious about the book...

There was nothing suspicious about the book your big
sister gave you for your birthday. A cheerful motley cover with a smiling pup, enthusiastic blurbs about how influential the author was.
"I hope you enjoy sis, I was told it's a... life changing read."
You whine pitifully whne you realize the book is nearly over...
The last few lines erase your ability to read, making sure you can't be changed again, just as it should be.
The door half opens, and you hear the most wonderful voice in the universe.
Your big sis ! Your mommy, you jump out of the bed, nearly collapsing on the floor because of the stupid human pajamas you're wearing for some reason, and run straight into her arms.
She squeezes you against her chest, and you melt in against her, inhaling her wonderful smell, her magnificent warmth seeping straight into your bones, forgetting all your stress in a second.
"Pheeeeeeeew" you whine, beyond relief.
