Libby Gallie has been left heartbroken after her 11-year-old Pomeranian, called Tishka, died after being struck by a car while being walked in St Brelade.
The States police have launched an investigation and Miss Gallie has taken to social media urging Islanders to come forward with any information.
In a Facebook post, she said: ‘Walking my dog and a car came flying down the hill at about 40 miles an hour and ran over my dog and didn’t even stop to check if it was okay, and sadly passed away.
‘If anyone has seen this car it was a dark blue Titanium Ford Focus or Fiesta and it was a woman in the car.’
She added: ‘I was in too much shock as I was checking if she was okay to check the J-plate. If anyone has seen this please get in contact. May she rest in peace.’
Miss Gallie has received hundreds of messages of condolence on the Jersey Dog Forum Facebook page following the incident on Mont ès Croix, near Beauport, at about 7pm on Saturday.
Under Jersey law, motorists must stop and inform a police officer if they are involved in a collision with a person or certain animals, including dogs.
Despite a campaign last year, drivers are only obliged to inform the JSPCA, and not the police, if involved in a collision with a cat.
A petition calling for cats to be given more protection was debated by the States last year, but it was decided that amending the Road Traffic Law would place too much extra burden on the police.
Anyone with information is being asked to phone the States police on 612612 or Crimestoppers on 0800 555111.
