The “district central” could stand for dog city. Here in Bogota, I see lots of Rottweilers, German Shepherds/Alsatians, Golden Retrievers, and Golden Labradors standing guard, walking with their guards, sniffing packages, sniffing cars, and spending much of their working lives not on a leash (okay, not the Rotties — they are always leashed and muzzled even though they are calm and well-behaved).
While there are some street dogs around, the vast majority of dogs that I see are well-cared for and well groomed. The wealthy have their dogs picked up for doggy daycare every day, and every morning, I see dog walkers with up to ten dogs out for their first walk of the eight-hour doggy day. I’ve seen all shapes and sizes of dogs. (Recently, I got a dog kiss from a passing Retriever as he pulled his child along at the other end of the leash. So, although I wouldn’t approach strange dogs, they don’t seem to feel the same way about us humans.)
As Bogota is also a city of constant signage and cleaning, there are many signs about cleaning up after your dog. I’ve included some here.
