Dogs Trust Harefield is desperately appealing for help in finding a young dog called Maggie currently missing in Wheathampstead.
The black and tan crossbreed went missing soon after being rehomed to new owners last week.
Sian Fairlie, Dogs Trust Harefield supporter relations officer said: "Maggie is very nervous, especially of men and likely to be frightened and confused by her unfamiliar surroundings.
"We urge people not to approach her but to please call us immediately. She is primarily tan in colour and is microchipped.”
Anyone with information should call Dogs Trust Harefield on 01895 453 930.
