The Field Spaniel is a medium-sized dog breed of spaniel type. They were originally developed to be all-black show dogs in the late 19th and early 20th centuries and were unpopular for work as a hunting dog. However, during the mid-20th century they were redeveloped as a longer-legged dog that was more suitable to be used for field work.

Questions people ask

Adult males usually weigh 18–25 kg and females 18–25 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 Field Spaniel 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.
The median is 13.1 y. Median survival across 378 UK dogs (VetCompass, McMillan 2024) · half live 10–15 y. How the later years go comes down to weight, teeth, exercise and regular check-ups far more than to the breed.
