Disney's Donald Duck (created 1934) is rendered 唐老鸭 — literally 'Tang [Don]-Old-Duck'. The matching name 米老鼠 (Mǐlǎoshǔ, Mickey Mouse) follows the same template: phonetic syllable + 老 + animal.
memory
Easy mnemonic: 唐 picks up 'Don', 老鸭 (lǎoyā) literally means 'old duck' — and Donald is the irascible elder figure of his family.
