As police look for a man believed to have fatally stabbed a dog at a Perth park, her owner has cried while describing the moment she discovered the beloved Labrador with "blood all over her".
The 22-year-old woman, identified only as Bridgette, said she took two dogs to Apple Blossom Polyantha Reserve in Mirrabooka about 6pm on Wednesday and let them run around off their leads.
Bridgette said she saw her four-year-old pet Luna approach a man, who also had a dog, but did not hear any barking or yelping as the man bent down.
She tried to speak to him but he left and jumped over a fence, which she thought odd.
Bridgette put her other dog in her car and went looking for Luna, expecting to find her sniffing around a tree.
"I get closer and I realise she's on the floor, blood all over her and I just drop and start screaming and screaming," she told reporters on Thursday.
Bridgette took the dog to a veterinary hospital but the pet could not be saved.
Anyone with information is asked to call Crime Stoppers.
PETA (People for the Ethical Treatment of Animals) has also offered a reward for information leading to the conviction of the person responsible.
