Twin brothers Roman and Raoul Krohn said they came up with the idea for Cold and Dog frozen yogurt when they were 9 years old and their grandmother told them not to give ice cream to their dog because it could be deadly, The Local.de reported Thursday.
The brothers, now adults, said they sampled all the flavors before giving them to their dog, Charlie.
"The wild salmon flavor tastes fishy with a light fruity note. The beef flavor is in comparison less intensive," Roman Krohn said in an interview with the Berliner Zeitung newspaper.
The Krohns said their frozen yogurt is available at various stores around Berlin for $2.83 for a tub containing about three scoops.
