A personal trainer who lost nearly all his vision at 41 years old says receiving a guide dog has been "life-enhancing".
Mark Long, 43, from Gloucestershire, was diagnosed with retinitis pigmentosa aged 12, but his conditions worsened in 2021.
He has now adapted to sight loss and launched his own gym at home, in Stonehouse, so he can work alongside his guide dog, Mary.
"For me to be able to have that little bit of independence again is encouraging me to be a better person," he said.
