Remove the black rubber diaphragm from the mask. Hold the mask 6 inches from your pet’s face and start the flow of oxygen. Slowly place the mask over your pet’s nose, giving them time to acclimate to the oxygen flow and the presence of the mask. Most pets accept the mask once they feel the effects of the oxygen.
