Down and Out in Las Vegas.
I recall once, years ago, seeing a homeless man with a dog. I felt a bit angry that this man was using an innocent dog in order to get more money. I’m happy to say that I am more socially aware now, and realize that the homeless see their animals as companions and more, as family.
I've learned that my response back then was not so unusual. Many people feel that homeless people with pets are being selfish and that they shouldn’t have a pet if they can’t even take care of themselves.
In fact, these animals are a lifeline to the homeless, who will often go without food to feed their pets. In many cases, the pet has become homeless along with the person. In other instances, homeless people take in street animals, often saving them from abuse or euthanasia.
