Is an AirTag necessary for a dog?

The function doesn't work if it's more than 10m away, which is a drawback. So, whether you need it or not... Today, I'll tell you why I bought an AirTag. AirTags are tags made by Apple to prevent losing items. There was an incident where a dog was lost in an apartment complex near my house. I thought a dog could easily get lost even within the city, so I bought an AirTag. The price was 39,000 won. It's engraved with my dog's name. The official case is quite expensive, so I bought a separate one. AirTags have the function to pinpoint the exact location of an item, but they have a fatal flaw in Korea. If the AirTag is more than 10m away, it won't be recognized. Due to Korean law, map data from foreign companies cannot be exported, so it won't show up on the map. You might think, "Then what's the point?" It's true that it's a half-baked feature domestically. So, is an AirTag really necessary for a dog?
