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.
If you see your pup's tail tucked in between her legs, the most likely reason is fear. When she's scared of something, she lowers her ears or points them back and hides her tail. The something could be a clap of thunder, the approach of another dog or walking into unfamiliar territory, such as a friend's house or the vet's office.
