Liam

Liam is the Irish short form of Uilliam, itself an Irish form of William, from Old High German Willahelm meaning 'resolute protector' (wil = will/desire + helm = helmet/protection). From a minor nickname in Ireland, Liam became the most popular boy's name in the United States from 2017 onward.

Liam is the definition of a name that transcends trend without losing momentum. It's been America's top baby name for years, which means that naming a pet Liam carries a kind of warm irony — giving a dog a human name that is itself extremely current. Pets named Liam tend to have owners who gravitate toward the approachable and familiar over the exotic, and that instinct usually produces a deeply affectionate, well-adjusted animal. Strong, simple, easy to call: Liam works for any energetic, loyal male dog.
