Advancing Canine Welfare
HDogz is also home to the Higgy Dog Fund. Through the fund we help support canine welfare projects around the globe.
5% of HDogz revenue from private sessions and Canine Cognitive Behavioural Therapy Programmes will be allocated to The Higgy Dog Fund.
This may include supporting rescue organisations, helping individual dogs and their guardians access essential behavioural or welfare support, contributing to education or research, and backing other projects that align with our mission to create a better world for dogs.
HDogz is committed to Non-Aversive Methodologies
All conditioning work is ethical, force-free and non-aversive..
HDogz also offers Canine Cognitive Behavioural Therapy (CCBT) — a distinct therapeutic approach developed by PhD Billie Groom at the Institute of Canine Psychotherapy. CCBT is also evidence-based and non-aversive.
All programmes are tailored to You & Your Dog. Every programme is individual. Age, breed, behaviour, environment client & dog backgrounds all shape the approach taken.
