This Remembrance Sunday Anna is joined by British Army veteran, Richard Means and his PTSD Assistance Dog Ziggy, for a walk on Hampstead Heath, talking about the invisible disability of mental health, and how Ziggy has turned his life around.
Remembrance Sunday is when animal lovers don a purple poppy to commemorate the animals that served in the Armed Forces. The PDSA's Dickin Medal is the 'Victoria Cross ' and recognises animals' bravery. In its 77 years only one cat has ever been honoured with this prestigious accolade.
