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.
Shadow of Chernobyl
Blind dogs can be found in almost any area of the Zone but they tend to be most dominant in the Great Swamp, Cordon, Garbage, Agroprom Research Institute, Dark Valley, Wild Territory, Army Warehouses and Pripyat. In Shadow of Chernobyl, a fairly large pack of dogs have made a nest just outside Rostok.
