Lost: Australian silky terrier cross Clyde went missing from Elabana Crescent, Castle Hill on December 16. He has a tan head, legs and behind and black undercoat. Contact 0418 293 094.
GUNILLA Denton-Cook knows the feeling of dread that hits owners when their beloved pet goes missing.
Her 11-year-old Australian silky terrier cross Clyde ran away after fireworks frightened him in mid-December.
She has spent three weeks scouring the neighbourhood, posting 'lost' flyers and calling local vets and shelters to try and find him.
And she's not alone.
Many pets run away during the holidays when they hear fireworks or their owners go away.
"We just panicked," Mrs Denton-Cook said when she realised Clyde had run away.
She says not everyone is aware of what to do in the situation, and there's a misconception pet owners should call the RSPCA, who rescue abused animals.
Pet owners should first call local veterinarians, council pound and shelter to see if their pet has been taken there.
