A Shih Tzu (UK: /ˌʃiːˈtsuː/, US: /ˈʃiːˌtsuː/; Chinese: 西施犬; pinyin: Xī Shī quǎn literally 'Xi Shi dog', also spelled Shittsu) is a toy dog breed, weighing from 4 to 7.25 kilograms (9–16 lb) when fully grown. The breed was developed in China. The Shih Tzu is a sturdy little dog with a short muzzle and large dark brown eyes. Because of its friendly nature, the Shih Tzu tends to interact well with other dogs and with children and adults. They do well with singles, couples, and families with older children. They are generally well behaved and suitable for families. The Shih Tzu has been prominently featured in various films, including the mockumentary comedy film Best in Show (2000) – with a Shih Tzu named Miss Agnes; , the dark comedy crime film Seven Psychopaths (2012) – starring a Shih Tzu named Bonny and in the animated comedy film The Secret Life of Pets 2 starring a Shih Tzu named Daisy.
