I read a ton of shifter romance, and the classic for this is definitely 'Alpha and Omega' by Patricia Briggs. It's not strictly a romance series, but the dynamic between Charles and Anna is exactly what you're asking for. Charles is this massive, incredibly powerful werewolf Alpha, all about control and dominance, yet he's gentle with Anna in a way that makes the power dynamic feel protective, not scary.
If you want something spicier and more focused on the pack hierarchy, try the 'Green Creek' series by TJ Klune. It starts with 'Wolfsong'. Ox is human at first, but Joe is the alpha heir, and their story builds this epic, soul-deep bond. The dominance is there in how Joe claims his territory and people, but it's wrapped in so much yearning and found family. The audiobooks are narrated beautifully, really capturing that growly, possessive tone.
A newer one that surprised me is 'The Tyrant Alpha's Rejected Mate' by Cate C. Wells. The title says it all. The alpha, Wyn, is a huge jerk at first—super dominant and aggressive in a way that skirts the line of dark romance. The audio performance really sells his growly commands and the tension. It's a great pick if you like your alphas a bit morally grey and your stories high on angst.
