A dog savagely attacked a family pet in Twickenham riverside.
"Billy" a 15-year-old cross between a shar pei and a Chinese crested, was left with several bite wounds after the mauling and police hope releasing this image will help their investigation.
According to officers a ginger dog, walking without a lead, jumped on Billy and repeatedly bit him.
The attack happened on August 17 at about 3.30pm.
The owner of the suspect dog was a white male in his 60s, with grey hair.
