Questions people ask

Adult males usually weigh 20–60 kg and females 20–60 kg. Most are close to their full size by around 13 months, though the last little bit of filling out takes longer. Growth reference: Hawthorne et al. 2004, WALTHAM (five giant-breed fits, n=35).

No American Bully 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.

10–12 y — the usual range. Wikidata (CC0) · 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.
