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.
For help with figuring out what the tail wag means, look for the direction of the wag or at how fast his tail is moving. Studies show that dogs wag their tails to the right when they are happy and to the left when they are frightened. If Baby wags her tail high and back and forth, she's in her happy place.
