The bond between dogs and humans is like no other. Dogs feel empathy for us, can sense chemical changes in our bodies and even read and react to our emotions. In the UK, assistance dogs are commonly paired with physically disabled people, to assist them with the practicalities of day-to-day life. But in the United States, they’ve gone a lot further. Dogs are being used to help people with conditions like PTSD, Tourette’s, Panic Attacks and Autism. The results are life-changing.
