Avery ranks #851 with 138 registrations, registered neutral. The name is an Old English unisex name (a variant of Alfred meaning roughly "elf-counsel") and on a pet license the neutral gender registration is meaningful: the name has shifted strongly to female on US baby registries while staying unisex on pet paperwork.
The unisex-pet register
Avery sits with Riley, Charlie, and Quinn in the cluster of names whose human-side gender shifted in recent decades while pet registration stayed flexible. Pet owners often pick these names precisely because they don't lock the dog or cat into a binary gender register. The neutral registration on Avery's slice (rather than F or M) suggests deliberate ungendered framing.
Sound and breed lean
Two syllables, front-stressed (AY-vree), with an open vowel opening and a soft -y close. The name calls smoothly outdoors but lacks sharp consonants for chaotic-park recall. Avery lands across breed types but appears notably on quieter medium dogs and shorthair cats: golden retrievers, labrador mixes, gray tabbies, and rescue dogs whose temperament owners read as adaptable and sensitive.
The counter-reading
The honest concern is that Avery is currently top-50 on US baby registries (as a girl's name primarily), which means high human overlap. The human Avery page shows the strong upward trajectory. Households who want the unisex-pet register with lower human overlap might consider Riley or Sage.
