Puptides : Peptides, Paws, and Possibilities

by Hattie Williams

They aren’t just dogs. They’re family.

And when the zoomies slow down, the stairs get harder, the scratching won’t stop, or your once-energetic pup simply isn’t moving like they used to, you start asking questions.

What else is out there?

Peptides, Paws & Possibilities explores the emerging world of peptide research through the eyes of the people who love their pets most.

Written for curious dog moms, dog dads, researchers, biohackers, and pet lovers, PupTides translates complicated science into an approachable conversation about what researchers are studying—and why peptides have begun finding their way into conversations about canine health, recovery, aging, mobility, inflammation, mitochondrial function, skin, gut health, and more.

Inside, you’ll explore compounds including BPC-157, TB-500, KPV, GHK-Cu, Thymosin Alpha-1, MOTS-c, SS-31, LL-37, Epitalon, and others, along with emerging canine research, animal studies, community experiences, research stacks, and the questions that still remain unanswered.

But PupTides isn’t about starting with the peptide.

It starts with the pup.

With science, humor, real-world observations, and plenty of dog-park talk along the way, Hattie Williams invites readers to become better-informed advocates for the four-legged family members who depend on them.

Because ultimately, what every pet lover wants is pretty

More walks.
More tail wags.
More zoomies.
More snuggles.
More mornings together.
More good years.

For educational and research purposes. This book is not a substitute for veterinary care.

About the author

I'm a writer based in East London. I left education in my teens to pursue a career as a musician. I have toured Europe extensively, made three studio albums, and worked as a composer with my tracks still regularly featured on TV and streaming services across the world. In my mid-twenties I found myself working in publishing quite by accident, and an admin temping job turned into a twelve-year career in which I worked with some of the biggest authors in the world. I'm the former producer of the Iceland Noir Literary Festival.

My debut novel, BITTER SWEET, will be published in July 2025. My second novel, BEGINNING. MIDDLE. END. will follow.
