Last night I watched a most wonderful documentary about the many ways in which rescued dogs can help rescue humans, each of whom needs someone to lean on. It's called Shelter Me . A synopsis of the docmentary can be seen here . A snippet should be all that's needed to get you to watch it:
"The first episode shows how shelter pets  are helping our returning war veterans cope with PTSD . We go inside a women’s prison, where inmates train shelter dogs to become service animals for people with disabilities. We also see the journey of two stray dogs, from the day they are picked up on the streets and brought to the shelter until the day they become a beloved family pet. Shelter Me is about redemption, hope, helping others and making a difference
We all need someone we can lean on, and so do they (other animals). I was moved to tears of joy as I watched the bond develop between the humans and their new found companions. I think you will also be incredibly moved by this most-welcomed documentary that spills over with hope for those beings, nonhuman and human, who need help in a demanding world. While some might question the scientific data about such relationships , these stories show clearly that dogs and humans form incredibly strong and reciprocal social bonds. Each becomes the life-line, the much-needed oxygen, for the other.
