@Palleas @11ty nice! I'm not sure what the advantage might be of separating the data out into post files? You could probably dynamically created posts at build time if you wanted them to have their own pages.
But the more important question is, are they unique dog counts or can you count the same dog more than once? 🐕
Or actually, if you wanted to use something like #pagescms to manage your content that might be a reason to have seperate files, maybe.
