In American English, if one acquires a dog (or other animal) from the SPA (etc), a lost or abused dog, in short one not purchased from a pet store or a breeder, the dog is called a "rescue dog." This is not un chien de sauvetage: The 'rescue' in English is what the people have done for an animal that may have been destroyedI. It is sometimes used as an adjective (a rescue dog/horse) but has become common to use "rescue" simply as a noun. "My dog is a rescue." Is there an equivalent in French?
