Approximately 25 million Americans have post-traumatic stress disorder (PTSD), which is 8% of all adults in the United States. Some of the symptoms of PTSD can be debilitating, and without treatment, many who suffer with it are unable to work, have a relationship, or even do everyday activities without an anxiety attack. Recently, therapy dogs have been found to help those with PTSD have fewer symptoms, and some of the best are those that are able to provide comfort and affection when needed. Experts have found that a therapy dog can lower your heart rate and blood pressure, reduce anxiety, and increase the endorphins that make you feel good. These pooches must be naturally friendly, affectionate, calm, obedient, and have the ability to adapt to many situations. While just about all breeds can be trained for this, some are more suited than others. Check out these top breeds for help in calming your PTSD symptoms.
