Their Mom’s Not There
The firefighters do not know why the mother is not with her little ones. However, the baby animals can’t get into the sewer. It may be possible if it is a wild animal, but if it is not, it may be a different story since the grate has a small gap that animals can fit. There is no way a puppy-like animal can fit into that kind of grate.
Are They Abandoned?
Before they can rescue the pup, the firefighters need to know the structure of the sewer. There is a chance that the mother and father are around in the area, but they will be terrified when they hear the firefighters’ siren. Until that moment, they do not know what kind of animals that they are saving since the place is dark and deep.
