Police and emergency services are continuing to search for a Melbourne man and his dog who went missing while bushwalking in Victoria’s high country on Friday.

Jeremy Boyden, 24, was on a day hike with his father near Dargo in eastern Victoria when he went missing in the afternoon.

Inspector Rob Wallace said Mr Boyden’s father searched by himself for a couple of hours before raising the alarm. There were now more than 60 people involved in the search, including the air wing, mounted branch and dog squad.

“There’s a lot of resources up there looking for this fellow,” Inspector Wallace told ABC Gippsland.

“Last night was very cold, of course, so it’s starting to get a bit of a concern.”

Mr Boyden was last seen with his tan-and-white-coloured Jack Russell named Rocky near the nine-kilometre post on Dargo High Plains Road, in the Wongungarra area.

“It is fairly steep, rocky country around there so it is hard for all our searchers to traverse,” Inspector Wallace said.

“He did have a mobile phone with him earlier in the day but his father thinks that he actually lost that in an earlier walk.”

Inspector Wallace said Mr Boyden was only equipped for a day hike, but was fit and healthy.

“He did have a small amount of food with him at the time,” he said.

“His clothing, while it is adequate, a jumper etc, he’ll still be very cold.”

Mr Boyden was last seen wearing a green and gold jumper and blue tracksuit pants.
