There is a simple truth to sharing life with a dog: we, as humans with the bigger brains and opposable thumbs, are ultimately responsible for every interaction our dog has with the world. When we behave irresponsibly, it's not only our dogs that pay the price, but sometimes, entire communities. When we behave responsibly, we have the opportunity to be agents of change, We can change minds, we can change perceptions and we can open hearts.
