Rescue dogs are canines that have been saved from shelters, abusive situations, or abandonment. They are often trained to help people in various ways, including providing companionship, emotional support, or assistance to those with disabilities. Many rescue dogs come from diverse backgrounds and can be of any breed or size. Organizations dedicated to animal welfare, such as animal shelters and rescue groups, work to rehabilitate these dogs and find them loving homes. Adopting a rescue dog not only gives them a second chance at life but also helps reduce the number of animals in shelters.
