Dog Dies After Swimming in Popular Bratislava Lake, Owner Warns Pet Owners

A woman is warning dog owners to avoid Zelená voda, a popular recreational lake near Bratislava, after her dog died following a swim there. The animal fell ill and perished shortly after entering the water, prompting its owner to alert the public about the potential danger. Zelená voda, whose name means "Green Water" in Slovak, is a well-known bathing and leisure area frequented by both people and their pets, particularly during warmer months. The cause of the dog's death has not been confirmed, but green-colored water in lakes and reservoirs is often associated with toxic blue-green algae blooms, which can be lethal to animals — and dangerous to humans — when ingested or absorbed through the skin. Pet owners are urged to exercise caution and keep animals away from the water until authorities investigate the incident.
