Rescue dogs are a vast mixture of dogs that have come from all walks of life. Not every dog in a shelter will have been neglected, abused, or abandoned. Many will have come from wonderful homes where due to death, illness, or circumstances beyond the owner's control, the dogs now found themselves in a shelter or rescue center. While it is true that issues such as separation anxiety can be part and parcel of pet adoption, this can be counteracted with love, patience, and time.
