At a glanceThe International Sheep Dog Society was founded in 1906 with a purpose connected to shepherding, stock management and improving the sheepdog.WORKING DOG reference library · Added 2026-10-19 · Editorial guideKey factsISDS founded1906 [source]Start with its own accountThe Society’s explanation of its purpose is a primary starting point for understanding the institution. Keep that founding purpose distinct from the histories of individual trials, regions and dogs.Place records in contextWhen reading a result or pedigree, identify the issuing authority and date. A modern rulebook cannot automatically establish how an event was conducted a century earlier.Build a documented timelineUse dated records for institutional milestones and attribute personal recollections. Avoid describing one organisation’s history as the complete history of working sheepdogs worldwide.For a particular dog or trial, identify the contemporary document before attaching a historic milestone. A later anniversary narrative may guide discovery but should be compared with the original record where available.Keep institutional history separate from an individual dog’s pedigree claims. Use the relevant primary record for each relationship instead of letting a general historical overview stand in for evidence.Preserve the scale of the claimThe ISDS founding date is an institutional milestone, not automatically the beginning of sheepdog work or trialling in every country. A useful history distinguishes the organisation, its major events, regional clubs and individual dogs. Use contemporary rules and reports for claims about an older trial and keep later anniversary recollections attributed. When connecting the Society’s work to another country, identify the actual relationship or adopted rules rather than assuming a shared Border Collie tradition establishes formal affiliation or identical administration.Common questionsDoes the ISDS founding date mark the start of all sheepdog trialling?No. It is an institutional milestone. Regional work, events and other organisations need their own histories and evidence.Sources & further readingReferences for this guide.
