Dog poisonings spread from Parque España to Condesa streets, four dogs dead

Four dogs have died and two others remain under veterinary care after suspected poisonings in Mexico City's Condesa neighborhood. The first cases were reported on October 27 when a veterinary clinic on Pachuca Street alerted police about dogs showing intoxication symptoms after walking in Parque España.

Residents say they now avoid the park and inspect sidewalks, benches, planters, and playgrounds for baits. Toxic substances have reportedly been hidden in pieces of bread, sausages, salami, and meat, sometimes with blue capsules inside.

“I will go to the last consequences and there will be consequences.”

Brenda Gómez Magaña's two dogs, Siberia and Kiara, fell ill on October 27 after visiting the park. Both animals received treatment at VETME Condesa Veterinary Hospital and showed improvement by October 29, according to their owner.

Authorities have secured at least 14 possible baits across Condesa, with around ten new items found on Wednesday alone. Some were located in the park and others on public roads near Juan Escutia and Amatlán streets.

Forensic tests identified methomyl, a highly toxic insecticide and acaricide, as the substance involved, according to Mexico City prosecutor Bertha Alcalde. The PAOT environmental agency has filed a criminal complaint with the capital's prosecutor's office.

Officials warn that formal citizen complaints remain scarce, with only one official report filed despite multiple cases. They also caution that some evidence lost legal value because residents handled samples before experts arrived.

Cuauhtémoc Mayor Alessandra Rojo de la Vega delivered neighbor-provided videos and photos to prosecutors on October 29, allegedly showing a person linked to the incidents.
