A police sniffer dog took just two minutes to sniff out a wedding ring after a man tossed it away following an argument with his wife.
German Shepherd Odin quickly located the lost item on a grass verge in Harborne, Birmingham, on Saturday.
His handler had pulled over after seeing two men use a torch to search a patch of grass for the lost band.
West Midlands Police said the "hugely embarrassed" man regretted his momentary loss of temper and had been searching for the jewellery for some time.
Dog-handler Pc Carl Woodall said: "Apparently the man pulled the ring off and threw it in a momentary loss of temper, but very quickly regretted his actions and was desperate to find it.
"Our dogs are trained to sniff out human scent.
"The men said they'd been looking for quite some time and the ring was quite small, so I wasn't confident there'd be enough scent for Odin.
"But he proved me wrong and indicated by the ring in a matter of seconds. It was in grass a couple of inches long."
Pc Woodall added: "It was pitch black. They could have spent all night and still not found it.
"Odin got a pat and thanks all round. It's nice to be nice and I was back on patrol in less than five minutes."
