The Manchester Terrier is a breed of dog of the smooth-haired terrier type. It was first bred in the 19th century to control vermin, notably rats, at which it excelled. So efficient at the task was it that it often appeared in rat-baiting pits until that sport, which had effectively been illegal in the UK since 1835, finally died out at the beginning of the 20th century.

Questions people ask

Adult males usually weigh 5–10 kg and females 5–10 kg. Most are close to their full size by around 17 months, though the last little bit of filling out takes longer. Growth reference: Salt et al. 2017, WALTHAM (6.5–9 kg band).

No Manchester Terrier 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.

15–17 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.
