It is bred first and foremost for work, so its size, coat and build vary from region to region.\n\nToday Koolies also shine in agility, tracking, therapy and as family companions, provided they get plenty of training, exercise and mental challenge.","history":"Koolies descend from British working dogs brought to Australia in the early 1800s. They were once misleadingly called German Coolies or German Collies, a name that stuck even though their ancestry was largely British.\n\nFarmers in different regions selected dogs to suit local needs, from tall cattle musterers in the north to smaller sheep dogs in Victoria. Breeders today work to keep the gene pool healthy through DNA and joint testing.","appearance":"Koolies are lean, athletic dogs, usually a little longer than tall. Males stand roughly 43 to 51 cm and females a little less, though regional types differ in height and bone.\n\nThe merle pattern is the most recognised look, often with striking blue or odd-coloured eyes, but solid and bi-coloured dogs are common too. Coats are most often short and smooth.","personality":"Koolies are patient, dedicated and eager to work, with a quiet, upright style around stock. Some can seem reserved or shy with strangers, so early socialisation and a consistent, kind approach matter.\n\nThey bond closely with their people and thrive when given a job to do, whether that is herding, sport or simply learning new tricks.","care":"This is an active dog that needs daily vigorous exercise and real mental work, such as training games, agility or herding. A bored Koolie can become restless or anxious.\n\nGrooming is simple. Short coats need only an occasional brush, and longer coats a little more attention. Clean up after seed-heavy or muddy outings.","health":"Koolies are generally robust, with a median lifespan of about 15 years. The small gene pool means hip and elbow scoring and DNA screening are important. Breeding two merles together risks deaf or blind puppies, so merle testing is advised."},"recognition":{"fci_number":null,"fci_standard_url":null,"akc_url":null},"sources":{"wikipedia":"https://en.wikipedia.org/wiki/Koolie","wikidata":"https://www.wikidata.org/wiki/Q38951","wikipedia_revision":1376294375},"profile":{"written_by":"AI model (Claude Sonnet) from the sources above","written_at":"2026-10-15T13:37:29Z"}}}
