Neglected dogs are sometimes aggressive as a reaction to being victims of abuse, or simply because they didn’t receive the affection they needed. Animals that suffered from abuse can also find it extremely difficult to trust people again and often don’t allow anyone near them. In these cases, it’s extremely important that only those with experience try to interact with the animals, since there is the risk of them being extremely dangerous. The dog in the video below was chained up to a fence most of his life. The way it affected the dog’s behavior speaks volumes about why continuous tethering of dogs should be banned.
