Matching Knitwear for
You and Your Dog.

Thoughtfully made in small batches, with care for animals, people, and the planet

About Maison Sou

Maison Sou is a Japan-based brand creating matching knitwear for dogs and their owners.

We believe everyday life with dogs should feel warm, comfortable, and quietly stylish.

As a young brand, we continue to learn, refine, and improve with each release.

Our goal is simple: to create clothing that feels good to wear, lasts beyond trends, and becomes part of the memories you share with your dog.

Our Commitment to Sustainability

Maison Sou is built as an ethical and sustainable fashion business.
We use recycled materials instead of low-cost acrylic or polyester. We avoid mass production and produce only what we believe will be worn and loved. We continue to explore recycled and natural materials for future collections. Quality and longevity come before trends
Designed for Dogs, Tested by Dogs

We want as many dogs as possible to enjoy matching fashion with their owners.
To achieve this, we work with dogs of different breeds and sizes, gathering real feedback through fittings and wear tests. Each design is adjusted based on comfort, movement, and ease of wear — because a sweater should never cause stress for your dog.
A portion of Maison Sou’s sales is donated to animal welfare organizations.

Looking ahead, we aim to collaborate with rescue dog and cat shelters to support adoption and encourage alternatives to purchasing pets through shops. We believe fashion can be part of a more compassionate system — for animals and for people.

Product Line Up

Maison Sou is a small business, and we do not produce in large quantities.
Because of this — and because we prioritize sustainable materials and ethical production — our pricing is positioned at a premium level.
We appreciate your understanding and support of thoughtful, small-scale craftsmanship.
