Treat these signs as an emergency
Open-mouth breathing, obvious effort or abdominal push, inability to lie comfortably, blue or pale gums, collapse, reduced responsiveness or rapid worsening warrant emergency contact. Open-mouth breathing in a cat is not routine panting; do not wait to see if it resolves.

Reduce stimulation and handling
Let the pet keep the position in which breathing is easiest, with a quiet, comfortably cool environment. Use a carrier with a removable top for a cat when possible; support a dog on a flat surface without squeezing the chest or abdomen. Do not force a flat position, put fingers in the mouth or delay travel for video.
Section sources: AAHA: Preparing for a successful veterinary visit
Give triage the five facts first
State species, age and weight, when breathing changed, gum color and responsiveness, and possible toxin or trauma. Then ask about the entrance, parking and whether to wait in the car. If alone, drive safely and call as directed rather than handling a phone while driving.

Do not turn home care into a reason to wait
Do not give human medicine, cough medicine, sedatives or oxygen equipment on your own, and do not force food or water. If a clinic instructed a step, record its name and time for handover; the hospital must determine the cause and support needed.
