The Blue Mastiff was born from a real need: to find beautiful, quality walking accessories for Moscow, a 60kg Spanish Mastiff.

The search was not easy—most aesthetically pleasing options are designed for small dogs, and what exists for larger dogs rarely has the same level of finish.

That search gave rise to a project. And that project, to a brand.

Today, we design and craft leather accessories for dogs of all sizes, from XS to XXL, with the same level of attention for each one. Because size should not determine quality or design.

We work with European oiled leather and solid brass hardware—materials that improve with use and develop character over time. Each piece is handmade on demand, one by one. There is no mass production. When an order arrives, we start working on it.

In addition to the online store, we offer The Atelier Experience: small group gatherings in Madrid where anyone can create their own leather collar alongside us. A way to get closer to the process and the philosophy behind the brand.
