Should I go to the emergency vet?

Go now if the night panting comes with pale or blue gums, a swollen belly, or a dog that will not lie down. A warm room and a brachycephalic dog are enough reason for a same-day visit. Occasional panting after a late play session, in a dog that then sleeps, can be described at the next exam.

How much will treatment cost?

Night panting in a dog that cannot settle needs an exam for pain, heart disease, Cushing's, and overheating. Chest films and bloodwork are the common add-ons for an older dog. Ask for the estimate that matches the dog's age and gum color.

Can I treat this at home?

Cool the room, offer water, and count the breaths when the dog is at rest. A resting rate that stays high, pale gums, or a belly that looks larger should be seen promptly. A warm blanket on an already hot dog makes the panting worse.
