History & Origins
Domestic sheep (Ovis aries) were among the first livestock animals, domesticated from wild mouflon in the Fertile Crescent around 10,000 years ago and spread worldwide for wool, meat and milk. Centuries of selective breeding produced hundreds of regional breeds — from fine-wool Merinos to hardy hill breeds and rare heritage types — each shaped by local climate, terrain and farming needs.

Dorset (Poll Dorset) Common Health Issues
Conditions seen more often in this breed, and how owners and vets help manage them. This is general guidance, not veterinary advice — always speak to your vet.
Footrot
A contagious bacterial infection of the hoof, common in wet conditions, causing painful lameness, smelly discharge and separation of the horn.
Care: Keep footing dry, trim and inspect hooves regularly, isolate affected animals and treat promptly with veterinary guidance.
Mastitis
Inflammation of the udder, usually from bacterial infection, causing pain, swelling and abnormal milk — common in dairy cattle.
Care: Good milking hygiene and clean, dry housing help prevent it; a vet treats infections with antibiotics and pain relief.
Pregnancy toxaemia
A metabolic disease of late pregnancy — common in does carrying multiple kids — where energy demand outstrips intake, causing dullness, poor appetite and collapse.
Care: Feed rising-plane nutrition in late gestation, avoid over-fat or under-fed does, and treat early cases urgently with veterinary support.
