From the game's booklet:
«Bello and his friends have absconded during the dog show. Who will be the first to find Bello and his brother in the frolicking crowd? But it's not that simple, because Henry is the spitting image of the two dogs. Who collects the most dogs?»
Bello is a matching pairs game for children, with a twist. As the game goes by and players get more pairs, it's harder to claim new dogs by their right names.
