About Downward Sizing Dog

In Downward Sizing Dog, you’ll enter a world combining heart-warming stories with the scientific evidence proving small dogs are ideal companions:

  • They’re smart, they’re heroic, they’re clean, and they’re green
  • They travel big and live long
  • They’re better for our bodies and (often) easier on our wallets;
  • They’re as intelligent, as empathetic, and as entertaining as big dogs.
  • They’re perfect both for families on the go and especially for those of us enjoying the freedom of our fifties and beyond.

Whether you’re a fan of Great Danes or Dachshunds, Downward Sizing Dog will broaden your perspective on the canine kingdom, shedding light on the often underestimated smaller breeds and their significant role as human’s best friend.

Downward Sizing Dog is a “home-run book,” and a “lovely read” filled with “delightful insights into the world of small dogs”. So, sit back, curl up with your furry friend, and get ready to explore the world through a smaller, but equally lovable, lens.
