Training and Consultancy in Mental Health & Employment. At a time when mental health trainers/consultants seem to be everywhere, it can be difficult to find ones that truly stand out - and that's what makes BDLD different. We are a two-man social enterprise that brings not just the knowledge and skills, but also a dynamic, thought provoking and, dare we say it, fun atmosphere to our delivery. Whether it's accredited programmes such as Mental Health First Aid, Government courses such as Enhanced Mental Health training or our own, bespoke, workshops, Big Dog Little Dog ensures that all learners return to work with the skills/knowledge needed to do things differently. Otherwise, why bother?
