The term 'dog shelter' can be broken down into two crossword solutions: 'POUND' (5 letters) and 'KENNEL' (6 letters). A POUND is a facility that houses stray or abandoned animals, usually dogs, and is typically run by a local government. A KENNEL is a facility that provides boarding and care for dogs, usually on a short-term basis. Both pounds and kennels provide shelter for dogs, but the services they offer differ.
