Ryan is one of those solid Irish surnames that crossed into first-name use so completely that most people forget it started as a family name. At rank 1261 in the pet registry, it shows up on dogs whose owners skipped the clever wordplay and just named their dog like a person — which is a legitimate naming philosophy with a growing fanbase.
Sound and Stance
Ryan lands clean: two syllables, hard stop at the end, easy to call across a yard. Dogs called Ryan tend to be medium-to-large breeds where an action-name would feel performative and something human-scaled fits better. Think Labrador retrievers and Australian shepherds — breeds that get along with everyone but don't need a novelty handle to prove it.
Human-Name Crossover
The human side of Ryan has been riding a long plateau; it ranked in the SSA top 20 for decades and still pulls respectable numbers. That familiarity is exactly why it works on a pet. You're borrowing warmth people already trust without going so human that it feels like a bit. Compare Jack, Sam, or Charlie: all human names comfortably settled into pet use. Ryan is that tier.

Is There a Counter-Case?
The one honest limitation: Ryan doesn't carry any visual or personality cue the way food names or color names do. It's purely a conventional human name applied to an animal. Owners who want their pet's name to do some descriptive work will find Ryan a bit neutral. For everyone else, it's a reliable, friendly choice that ages well as the dog does.
