The term 'dog covering' can be broken down into three words: FUR (3 letters), CHILI (5 letters), and COAT (4 letters). FUR is the short, soft hair that covers the skin of many animals, including dogs. CHILI is a type of fabric made from wool, cotton, or synthetic fibers, often used to make coats for dogs. Finally, COAT is an outer garment worn by humans and animals alike, such as a COAT for a dog. All three words together refer to the various types of coverings that can be used to protect a dog from the elements.
