The Sister-Screened™ 5-Point Audit
The Sister-Screened™ Q&A
It means every product in our shop has undergone a professional audit. Our founder spent her career in children's nursing, reaching the level of Sister, where overseeing standards and managing risk as a professional requirement. We apply that same disciplined mindset to our treats - checking for ingredient integrity, sourcing transparency, and suitability before anything reaches our shelves.
No. We are professional quality auditors. While we don't provide clinical veterinary advice, we use the skills learned in a senior nursing career, specifically Triage and Clinical Audit, to screen out low-quality products and assist you in choosing the right level of treat for your dog.
Because not every dog chews the same way. In a professional environment, triage is about assessing risk and priority. We apply this to our "Triage Scale" (Levels 1, 2, and 3) so you can match a treat’s suitability to your dog.
Traceability is a safety requirement, not a luxury. By keeping our sourcing local to the UK and EU, we ensure higher animal welfare and stricter hygiene regulations. For our global innovations, we don't just buy off a shelf; we use UK-based specialists to audit those lines, ensuring our accountability never wavers, no matter where the ingredient starts its journey.
We focus on Chemical Integrity. Our audit distinguishes between "Aesthetic" chemicals (like dyes and bleaches used for looks) and "Functional" ingredients. We allow vegetable glycerin in our veggie treats because it serves a vital purpose: keeping the treat pliable so it doesn't shatter or become a sharp choking hazard. If an ingredient doesn't have a safety or health purpose, it’s out.
Once a treat passes our professional audit, it goes to our resident testing team: our three Staffies. They provide the "real-world" verification for joy and durability. If it passes this final test, it’s Dogtropolis approved.
Absolutely. The "Staffy Check" is our ultimate durability test. If a treat survives a Stafford's jaw without splintering or failing, we know it has the structural integrity required for our "Power" level. Conversely, if our dogs find a "Gentle" treat too high value to ignore, we know the palatability is exactly where it needs to be for even the fussiest eater.
