A beloved dog was killed in a hit-and-run in Hasland.
Six-year-old Rosie - who belonged to Anne Frost - was being walked on a lead by a family friend along the Calow Lane bridge when the tragedy happened.
Anne, 46, of Hasland, said: "A light Blue Astra came flying down the road, mounted the kerb and hit Rosie, killing her, then the driver sped off.
"I was at work at the time and when I found out what had happened I was absolutely mortified.
"Rosie was such a lovely dog, always very friendly and happy.
"I really miss her and I hope the person who did this is found and brought to justice."
Anne has reported the incident - which happened between 3pm and 3.30pm last Thursday - to Derbyshire police.
A force spokesperson urged witnesses or anyone with information to call 101, quoting reference number 1032 of January 31.
