During the Trobada Nacional dels Tres Tombs in Barcelona on May 3, 2025, a participating horse suddenly died during the event. The horse fell at an intersection, and veterinarians present certified its sudden and fulminant death. The incident led to the parade being temporarily stopped and rerouted, causing the cancellation of some traditional activities. This tragic event has reignited the debate on the use of animals in such celebrations, with animal welfare organizations calling for better regulation to prevent such incidents in the future.

The Foundation for Advice and Action in Defence of Animals expressed its rejection of the event on social media, highlighting the stress and suffering animals may endure during mass events. The death of the horse, which carried the banner of the patron saint of animals, put a damper on a day meant to celebrate Catalan cultural heritage, shedding light on the vulnerability of animals used in such festivities.
