Hi, here is how it's processed, for each dog if there is owner informations I put for the dog as living place the country the owner entered. I guess this works most of the time, but as we see not 100% (e.g. if the owner entered its contry of origin and lives outside it, or if there is co-ownership).
The best way for changes would be to modify (PM to Admin ?) your informations
