Chained dogs make up 25% of fatal dog attacks(AHS). Chained dogs are 2.8 times more likely to attack. The most common victim of dog attacks are children. The CDC found that of 50 children 1 year or older who were killed by dogs 28% wondered to close to a chained dog. Chained female dogs in heat can be repeatedly raped by multiple males (unwanted litters). Dogs require socialization as a basic need (much like food, water and shelter). To not provide one of the most basic needs amounts to nothing short of animal cruelity!
