Bamse, the 14 stone heavy St Bernard, saved the lives of two sailors during World War II, and there are already two life-size statues of the dog in Scotland and Norway.
Dr Andrew Orr from Montrose Heritage Trust, which commissioned the 8in (20cm) model, said there had been "countless inquiries" from people wanting to buy a "mini Bamse". The statue has been designed by the original sculptor Alan Herriot and will be manufactured in Scotland.
The life-size statue of Bamse in Montrose was unveiled by HRH Prince Andrew in October 2006. A half-sized bronze version was exhibited at the Imperial War Museum in London from 2006 until 2007 and is now on display at the Marine Museum in Horten, Norway. The biography that charts the life of Bamse recently made it into the Blue Peter Book Club.
The dog performed many good deeds while he was the mascot on the Norwegian Navy minesweeper the Thorrod, which was stationed in Montrose and Dundee. His exploits included going into the water to rescue a sailor who had fallen overboard and knocking over a knifeman who was trying to attack a young lieutenant. Bamse died in 1944 and is buried in Montrose with his head facing towards Norway.
Dr Andrew Orr said: "The trust is absolutely delighted with the finished product, a real work of art in its own right, a worthy tribute to the remarkable dog."
The Bamse mini statues are available online from www.ballantynes-walkerburn.com/. All sales will help the Montrose Heritage Trust, the Air Station and Frigate Unicorn to continue their valuable work.
