Only what holds up to bite work
If a product can't take a grown Pit Bull, it doesn't make the catalogue. We test every item with real dogs before we list it.
The pack behind the brand
Three people with a PPP dog. One shop.
Sin Bozal started in 2024, in a flat in Madrid, when the founder sent the fourth muzzle in a row back to Amazon because it wouldn't fit his Pit Bull. He rang his vet. He rang his trainer. Three months later they launched the shop they wish they'd had when they adopted their dogs.
How we decide what gets in
Four filters. If something doesn't pass all four, it's out of the catalogue.
A vet in every decision
Laura formulates the supplements. She signs off on the food. If she wouldn't recommend something to her own patient, we don't sell it.
Trainers, not influencers
The reviews come from real K9 professionals — sport trainers, breeders and police units. No paid affiliates.
Specialised to the bone
16 PPP breeds on file, an algorithm that cross-checks weight + jaw + temperament, a legal hub for every Spanish region. What an owner is looking for, all in one place.

All three answer your emails — and all three have a PPP dog.
