As the name implies, these dogs have lost their eyesight, possibly due to some form of warped, mutation-induced evolution. Rather than rely on eyes, Blind dogs have extremely keen senses of hearing and smell and can hunt, fight and navigate through pockets of radiation and fields of anomalies without much problem.
Blind dogs move in packs and will usually attack prey (Stalkers or other small mutants) that are alone. Though widely regarded as one of the least dangerous mutants in the Zone, a pack of Blind dogs can be a threat to a lone Stalker. They use their sharp teeth to wound and incapacitate victims. Keeping on the move will usually hold them at bay, but if you do encounter a pack, kill or wound one or two, and the rest will sound off a scared bark and retreat. if you stay in the vicinity, they often return to torment you, so once they run, go away from the area.
Shadow of Chernobyl
Blind dogs can be found in almost any area of the Zone but they tend to be most dominant in the Cordon, Garbage, Agroprom Research Institute, Dark Valley, Wild Territory, Army Warehouses, Pripyat and Chernobyl NPP. In Shadow of Chernobyl, a fairly large pack of dogs have made a nest just outside Rostok.
Call of Pripyat
Blind Dogs have received a more detailed appearance that can differentiate some from others, and like most creatures in Call of Pripyat, the have also received an improved AI. Instead of running in a pack directly towards you, then scattering around you, they tend to split the pack up where some attempt to flank you. They make use of annoying hit and run tactics. They also have increased health; they are somehow able to survive direct hits from shotguns loaded with buckshot rounds. This makes the blind dog slightly more dangerous than its predessors. Blind dogs can be commonly found throughout Yanov, Jupiter, and Pripyat. These blind dogs hunt Fleshes and unsuspecting stalkers, and are sometimes hunted by Pseudodogs, and tend to be the most numerous monster within a Controller horde.
