Questions people ask

Adult males usually weigh 9.1–18.1 kg and females 9.1–18.1 kg. Most are close to their full size by around 18 months, though the last little bit of filling out takes longer. Growth reference: Salt et al. 2017, WALTHAM (9–15 kg band).

No Miniature American Shepherd 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.
