Max the overweight Jack Russell has managed to lose a fifth of his body weight - after joining a pet fitness club. The six-year-old, who once weighed a staggering two stone and had a reputation for sticking his nose in sweets jars, also managed to lose 10cm off his waist. His owner Emma Harrison said her mother Sylvia, 80, had enjoyed taking Max for walks since he was a puppy, but after she developed painful arthritis, she increasingly struggled to control her dog's weight.

And Max was also put on a strictly controlled six-month diet and banned from having extra treats and biscuits to help him slim down. Ms Harrison added: 'We 're absolutely thrilled at how well Max has done.
