With heat indices of 101 on Saturday and 102 on Sunday, PETA is reminding pet owners of the dangers this weather poses for them.

PETA said that last year at least 163 dogs and cats reportedly died from heat-related causes and the actual figure is likely far higher as most deaths go unreported. “If you’re hot, dogs and cats who can’t sweat as humans do are even hotter,” the organization said.

PETA urges people to be on the lookout for animals who are in need of assistance, including those who may be experiencing heat stroke symptoms, and advises everyone to do the following:

Walk dogs during cooler parts of the day and limit the time they spend outside in the heat. Before walks, touch the pavement to ensure that it won’t burn dogs’ foot pads. In hot weather, walk only in the shade or on earth or grass.

Never leave animals outdoors in extreme heat or inside vehicles at any time.

If you see a dog showing signs of heat stroke including heavy panting, excessive drooling, vomiting, diarrhea, lethargy, difficulty walking, seizures, and collapse ensure that the animal is moved into the shade or an air-conditioned space, offer them water, and wet them down with room-temperature — not cold — water. If their owner isn’t around, call local authorities immediately.
