There Are Charities That Look After The Dogs
Clean Futures Fund is an animal welfare organization that works at Chernobyl and the surrounding exclusion zone to care for the dogs there. They send teams to the area every single year to work alongside workers at the power plant. The charity operates a center that cares for about 250 dogs at a time.
The charity workers do what animal welfare organizations would do for stray dogs in any urban environment. They feed them, spay and neuter them, and vaccinate them. They also play with them and even offer them scraps of food from their own meals. The Clean Futures Fund has been in Chernobyl every year since 2016.
