A loose dog that bit a pet-sitter and killed one of the dogs she was looking after is still at large. 

Zoe Hunt was looking after dogs Lola and Toby for her friend Karen Hart, who was on holiday, when she took them both for a walk in the Nythe area of Swindon on April 4 at 9.30am. 

She was on Nyland Road approaching her home in Purbeck Close when suddenly a 'black Akita X' came from behind her and immediately attacked Lola in what she described as 'an ambush'.

Lola died from her injuries and Zoe was bitten twice before the dog scarpered.

Now, Zoe and Lola's devastated owner Karen are trying to find out whose dog it was, and why they weren't there at all while all of this happened. 

Karen said: "The dog, a black Akita X has still not been found and it breaks my heart that justice has not been done for Lola

"And poor Zoe Hunt has been back to doctor again and more antibiotics for her infected bites

"Someone knows something."

A Wiltshire Police spokesperson said: "Witnesses to the incident should call 101 and quote crime reference number 54240038747."
