Diddly is devoted to her loving owners Anne and Sandy Fleming.
And the Marton couple return the favour to their 16-year-old fox terrier-Jack Russell cross.
Six years ago the dog was hit by a car, and her left back leg had to be amputated.

"She really started to slow down, and it was only determination that kept her going."
