She’s suffering heatstroke

Panting after running around or spending time in the sun usually isn’t anything to worry about, but keep an eye out for heat stroke if it’s been a particularly hot day. A dog that’s panting excessively and is also acting lethargic or confused, vomiting, drooling, or showing reddened gums might be overheating, says Paschke.

Get your dog to the vet pronto if you suspect heatstroke, and help your pet cool down in the meantime, says Gary Richter, DVM, holistic pet veterinarian. He recommends getting your dog out of the heat and rinsing her with room-temperature water—ice will actually work against your pet.

‘The ice is so cold that it causes the blood vessels in the skin to restrict, and circulation is not as effective,’ he says. ‘Room temperature … will ultimately help them cool down quicker and better.’
