In the past, most stray dog shelters were located near towns and villages, because the conflict between dogs and humans had gradually intensified, leading to the rapid establishment of several shelters.
However, in pastoral villages near River Source, because the area is so vast, those stray dogs don't really bother humans much, but rather cause trouble for animals.
The previous neglect was because driving aimlessly into the protected area to catch dogs just for them wasn't feasible. But now that they have been caught and sterilized, it seems somewhat inappropriate to release them back.
This was also the point Chen Ying discussed with Professor Bai; however, it is impossible for a private individual to fence off such a large area for a shelter, so ultimately, it's still necessary for local institutions to step in to handle this matter.
