Summer in New Zealand is a wonderful time to explore the outdoors with your pets—but our hot, humid weather also brings a serious risk: heatstroke. Heatstroke in dogs and cats is a life‑threatening emergency where body temperature rises dangerously above 40°C and organs begin to fail. Quick action can save a life.
