About the Sheep

Once thought of as purely livestock, sheep have grown popular as smallholding companions and lawn-trimming pets. A pet sheep that escapes the production lifecycle and receives smallholding-grade care averages 10-12 years, with good husbandry pushing several breeds past 14. Sheep are intensely social — solo housing creates measurable cortisol spikes and predisposes to digestive upset. A pet sheep tracked in human-equivalent years lets owners notice early hoof-rot, dental wear, and parasite-related weight loss before they cascade.

How Sheep age

A typical Sheep moves from lamb (0-1 yr) through hogget (1-2 yr) into adult (2-7 yr) and senior (7-15 yr). The lamb year compresses immune-system development and rumen maturation; weaning stress in this window has lifelong implications for parasitic susceptibility. Adult years are when wool, milk, or companionship roles stabilise. Senior signs arrive around year 8 — molars grinding down, slower flock pace, increased need for shelter from cold rain.

Senior Sheep care tips

Trim feet every 6-10 weeks; senior sheep struggle to wear hooves naturally.
Provide soft shelter; cold-rain exposure shortens senior lifespan more than any single factor.
Annual dental check from age 6; molar wear is the leading cause of senior weight loss.
Companion housing essential — solo seniors decline rapidly.
Body-condition score monthly; senior sheep hide weight loss under wool.

Common Sheep health concerns

Foot rot: Wet pasture and dirty bedding let bacteria inflame interdigital skin; trim regularly, treat early, and avoid prolonged standing in mud.
Internal parasites: Worm burden is the leading cause of weight loss in pet sheep; faecal egg counts twice yearly direct targeted dosing better than calendar treatments.
Pregnancy toxaemia: Late-pregnancy ewes underfed for twins or triplets develop ketosis; energy-dense feed in the last trimester is preventive.
