Extreme heat in Brazil, intensified by the El Niño phenomenon, has created significant health risks for pets, including the potential for hyperthermia, dehydration, and organ damage. Veterinary experts have identified vulnerable groups such as puppies, elderly animals, obese pets, and brachycephalic breeds like Pugs and Bulldogs.

In response to the rising temperatures, local authorities in Atibaia, through the Municipal Secretariat of Environment and Animal Defense, have issued specific safety guidelines. These recommendations include ensuring constant access to fresh water in shaded areas, avoiding walks during peak sun hours to prevent paw burns from hot asphalt, and monitoring for signs of distress like excessive panting or heavy salivation.
