God’s blessings on this wonderful man. How anyone can abuse an animal or neglect them is beyond me.
Many people are trash. Look at the number of abused and neglected children and elderly.
From the video only: I am guessing the German shepherd was abandoned because of bad hips. When you see him standing with his rear legs close together it is an indication of hip dysplasia.
He is going to get so much love back from that dog. I am lucky to have had animals that have never known a day being homeless or unwanted, and I have many that were until I adopted them. I wish none of them knew abandonment, but I can tell you the ones that have been abanadoned, you can tell they are grateful to be in a loving home, in a different way than the ones that have always been.
