POLICE are trying to track down the owner of a big white dog which attacked a chihuaha in Hagley.
It happened at 7am on Tuesday on Hagley Playing Fields, off Church Street.
The white dog, which was off its lead, caused serious injuries to the chihuaha during the attack and then jumped up an elderly lady causing her considerable distress.
The woman who was walking the big white dog was white with light brown hair and had a smaller dog with her.
After the attack police said she merely walked off without any concern for the distress her and her animal had caused.
Anyone who knows who she is should call police on 101 or Crimestoppers on 0800 555 111.
