This time we are looking at a triplet of signs found on the gates and fences of a dog park in Helsinki, Finland. The dog park had two separate areas, one for small dogs and the other one for large dogs. These show the respective texts of "ISOT KOIRAT Stora hundar" ("Big dogs") and "PIENET KOIRAT Små hundar" ("Small dogs") together with the city of Helsinki logo, blue background and white text. Each also has a stylized silhouette of a dog. Besides the two, there is a third sign saying "Welcome to the dogpark!" with further detailed instructions. This one also depicts three dog icons of various sizes.
The first thing to point out is the typical language selection here. In the two dog signs the Finnish text is shown first, in caps and in a larger font. The dog symbol is also interacting with the Finnish text, making it the primary language choice in these signs.
Another thing to note are the types of dogs shown here. The segregation is suggested to make sure small dogs have a safe place to play without the possible dangers arising from dogs several times their size. (The detailed rules dictate that big dogs can't go to the small dog pen, but small dogs can go to the big dog area at the owner's discretion.) But despite this base setting of implied danger, the big dog is not (to my eyes) shown as a dangerous dog. Just a big one. So the signs make sure not to invoke ideas of danger here, just size differences, as is further emphasized in the generic size where three different sizes of dogs sit quite passively next to each other, providing both a common size scale and perhaps a message of peaceful co-existence?
