This is done by one or more of the following methods: back blows, manual chest thrusts, and finger sweeps. Once the airway is open, rescue breathing is started by means of mouth-to-mouth resuscitation (see artificial respiration). The third element of CPR is circulation, which begins by establishing the presence or absence of a pulse.
A tail that is consistently down may indicate that your pooch is in a substantial amount of pain. Some of this discomfort could stem directly from the tail although it can also be linked to pain incurred from the base of your dog's spine or his hindquarters.
Ears down can also mean friendliness. If she's looking at you, with ears back, wagging tail and lip licking, then it should mean that she's happy to see you. If she's afraid of you, she would avoid eye contact and even go away, and even with tails between her legs instead.
