If hikers are determined to bring their animals with them on hikes, Jeffers suggests going early in the morning or late in the afternoon, and bringing lots of water ... more water than you think you need.
Jeffers also urges hikers to read their dogs' signals: "If they stop, don't make them keep going," and if they're straying off of paved trails, "the pavement is probably too hot for their paws."
All pet owners should take this advice from Jeffers to heart:
"Always remember they need water too, and they can't tell you they need water."
Parks officials are desperately working to prevent any more deaths, putting up signs and handing out water, but ultimately, it's up to the hikers to make sure their pets stay safe. Summer heat is dangerous for dogs all across the country -check out this list of signs that your dog is overheating.
