Sammi ranks at #884 with 133 entries, registered female. The name is the female respelling of Sammy, itself the diminutive of Samuel or Samantha. On a pet registry the I-ending spelling signals the female register specifically, separating Sammi from the gender-neutral Sammy that sits higher in the rankings.
The diminutive-respelling pattern
Sammi sits with Sandy, Penny, Cindy, and Lexi in the bouncy female-diminutive pet pocket. The I-ending is doing the gender work — same name, different vowel signal. Most Sammi pets are small-to-mid-size dogs whose owners wanted the warmth of Sammy without the gender ambiguity.
Sound and breed lean
Two syllables, front-stressed (SAM-ee), with the bright vowels and bouncy I-ending. Excellent close-range recall, soft enough not to startle. The name lands flat across breeds — Labs, Goldens, small mixed rescues, and family-pet picks generally.
The counter-reading
The honest consideration: Sammi is not formally distinguishable from Sammy in spoken use, so the spelling choice is essentially a paperwork preference. Owners who picked Sammi specifically did so to signal female on the registry form, not to change anything about how the name sounds. The human Sammi page shows minimal SSA presence; this is largely a pet-only spelling.
