Temperament

• Extreme work drive, focus, problem-solving ability.
• Loyal, responsive, sensitive to handler cues.
• High energy + high mental need = not a "pet" in conventional sense.
• Herding instinct: eye, stalk, chase – directed at children, cars, bikes if not channeled.
• Can be reactive/overstimulated; needs decompression skills.

Exercise & Enrichment – Non-Negotiable

• 2+ hours daily vigorous + complex mental work.
• Activities: herding, agility, flyball, disc, obedience, scent work, treibball.
• Without job → OCD behaviors (shadow chasing, spinning, self-mutilation), destruction.

Health

• Hip dysplasia
• Collie Eye Anomaly (CEA): Genetic test; choroidal hypoplasia.
• Epilepsy (heritable)
• MDR1 drug sensitivity: Ivermectin, loperamide, others – test or avoid.
• Neuronal ceroid lipofuscinosis (NCL) – rare, fatal; genetic test.
• Early-onset deafness (merle-related).

Training

• Positive, science-based; clarity + consistency.
• Teach "off switch" (settle on mat).
• Impulse control foundations.
• Sports provide structure + outlet.

Ideal Owner

Dog-savvy, active, time-rich (work from home, retired, flexible), seeking partnership in sport/work. Not for novice, sedentary, or long-hours-away homes. Rescue: Border Collie Society of America Rescue, Glen Highland Farm.

Border Collie vs. Australian Shepherd

• BC: Higher drive, more intensity, more sound-sensitive, longer legs, herding style (eye).
• Aussie: Slightly lower drive, more adaptable, natural bobtail common, upright herding style.
