The Xoloitzcuintle is one of several breeds of hairless dog. It is found in standard, intermediate, and miniature sizes. The Xolo has both hairless and coated types, with the latter fully furred. The Standard is the largest of FCI 234's 3 Xoloitzcuintli varieties: FCI 234: 46-60 cm for dogs and bitches alike, with a tolerance of +2 cm in top-quality dogs; the AKC calls this variety the Standard too and gives it 30-55 lb; one range for both sexes. Typically 13.6–24.9 kg full-grown.

Questions people ask

Adult males usually weigh 13.6–24.9 kg and females 13.6–24.9 kg. Most are close to their full size by around 15 months, though the last little bit of filling out takes longer. Growth reference: Salt et al. 2017, WALTHAM (15–30 kg band).

No Standard Xoloitzcuintli cycle figures are published here yet, so this is general guidance rather than a breed number: most females have a first season somewhere between six and fifteen months, and cycles then settle to roughly every 180 days. Smaller breeds tend to start earlier and larger ones later.

13–18 y — the usual range. Uncited — a general reference figure, not a published one · no measured cohort for this breed. How the later years go comes down to weight, teeth, exercise and regular check-ups far more than to the breed.
