The human-animal relationship ("HAI"), or"bond" has been defined as "a mutually beneficial and dynamic relationship between people and animals that is influenced by behaviours essential to the health and wellbeing of both. This includes, among other things, emotional, psychological, and physical interactions of people, animals, and the environment".
However, while that relationship is frequently beneficial, and could be improved in a way that would benefit people and animals alike, the sad reality is that the relationship is not always "beneficial" - to animals or people.
Does it make sense to you that if a person is capable of abuse of animals, they might also be capable of abuse of other people as well? And vice versa?
Over the past 35 years, researchers and professionals in a variety of human services and animal welfare disciplines have established significant correlations between animal abuse, child abuse and neglect, domestic violence, elder abuse and other forms of violence.
Mistreating animals is no longer seen as an isolated incident that can be ignored: it is often an indicator or predictor crime and a “red flag” warning sign that other family members in the household may not be safe.
There are several organisations that are active in the field of human-animal relationships, and the National Link Coalition is but one of them. But the NLC is a particularly good one in terms of the information it provides, and the initiatives it will make you aware of. Those initiatives include attempts to advance the law in this less than "beneficial" aspect of the human-animal relationship.
Take a look at their website (the link is provided for you below), and remember that they provide a regular newsletter as well.
