I haven't watched the episode with the culling yet (just finished Episode 3 last night and kind of dreading the next).
There is a charity that works to spay/neuter/vaccinate the stray dog population in the exclusion zone: https://cleanfutures.org/projects/dogs-of-chernobyl/. There is a large number in the area, and it seems like they flock towards the power plant because they are chased out of the forests by the wolves.
So if it makes anyone feel better, some of the dogs survived the extermination - not that living in the wild is a great life either for these animals....
