Police have released images of a badly injured man who was the victim of a "vicious and prolonged" assault in a bid to find who was responsible.
David Baird, from Kilbirnie, was attacked near his home while he walked his dog on a cycle path near the town's Stoneyholm Road on 27 October.
The 40-year-old remains in a critical condition in hospital.
Police will be at the cycle path on Wednesday to speak to anyone who may have been there last week.
Mr Baird was walking his black Labrador dog when he was attacked between 2115 and 2135 BST.
After the dog ran home, the victim's wife went looking for him. She called emergency services after finding him lying unconscious on a cycle path.
Det Insp Craig McArthur, of Strathclyde Police, said: "Although the response from the public has been reasonably good so far, we would still like to hear from anyone who may have been in the vicinity to get in touch.
"A number of officers will be at the location tonight in an effort to gather further information and perhaps jog someone's memory.
"I feel sure someone out there must know who is responsible for this vicious attack which has left Mr Baird fighting for his life and his family devastated by the consequences of this assault."
