Roo, a 5-month-old Chihuahua born without front legs, hops about outside his home in Nelson, Lancashire. See Ross Parry copy RPYDOG: A determined chihuahua born without front legs refuses to let his disability hold him back – by hopping around on his stumps like a KANGAROO. Loveable Roo was given to a rescue centre in Colne, Lancs. when he was only six weeks and now five months old, he has flourished. He has learned to move around using just his back legs – and hopping. Despite adapting to his condition, bosses at the centre are keen to get Roo even more mobile and are asking for help to design him some wheels.
