Animal welfare activists in Montenegro say a heat wave sweeping across western Europe is intensifying concerns about horses and other abandoned animals in the Balkan country. Multiple outlets report that activists are drawing attention to the risk to animals left without adequate shelter, water, or human care as temperatures rise. The reports describe the issue as a long-running problem, with abandoned horses persisting over years and decades. As the heat wave expands into the Balkans, activists express worry that soaring temperatures could worsen animal suffering and mortality, especially for animals that are unable to move to cooler areas or access sufficient drinking water. The coverage frames the activists’ response as an effort to raise public awareness and prompt action, while emphasizing that the situation is occurring alongside extreme weather affecting multiple European regions. Overall, the sources agree that the central concern is horse welfare in Montenegro and that the current heat wave is making existing abandonment risks more urgent.
