If possible, have another person call the veterinarian while you help your pet.
Check to see if your pet is unconscious.
Open your pet’s airway by gently grasping its tongue and pulling it forward (out of the mouth) until it is flat. Check the animal’s throat to see if there are any foreign objects blocking the airway (see the section above on Choking)
Perform rescue breathing by closing your pet’s mouth (hold it closed with your hand) and breathing with your mouth directly into its nose until you see the animal’s chest expand. Once the chest expands, continue the rescue breathing once every 4 or 5 seconds.
