From the minimum an animal needs to be kept humanely, up to the ideal setup. Bigger is almost always better — minimums are floors, not targets.

Minimum
Home with daily structured exercise
Apartment/house + 60 min daily exercise
Medium dogs need at least an hour of varied daily exercise — leashed walks plus off-lead play or training. Apartment living is workable only if exercise commitments are met every day; crate-train and allow supervised free-roam at home.

Recommended
Home with fenced yard + training time
House + fenced yard + 60–90 min varied exercise
A home with a securely fenced yard, daily walks plus off-lead play, and ongoing training keeps a medium dog mentally satisfied. Add a sport or hobby (fetch, scent games, agility intro) for breeds with extra drive. High-drive working breed — the recommended tier still demands daily structured mental work (training, scent games, herding ball, fetch with rules), not just walks.

Ideal
Active home with a job or sport
Suburban/rural home + secure yard + canine sport
Athletic terrier — weight pull, agility, or protection sport channels the drive. — ideal is acreage or rural property paired with a daily job or canine sport: herding stock, scent detection, agility, protection sport, sledding, gundog field work, or a structured working role. Without that outlet, expect destructive behaviour, reactivity, and welfare-relevant frustration.
Life & growth stages
How this animal changes through its life — each stage often has its own care, diet and space needs.

Newborn
Newborn mammals are nursed on their mother's milk. Many are born helpless — blind, deaf, and sparsely furred (altricial, as in dogs, cats, and rodents) — while others stand and follow within hours (precocial, as in hoofed livestock).

Juvenile
After weaning, juveniles grow quickly and become increasingly active, playful, and independent. Adult coat, proportions, and (in many species) the permanent teeth come in as they approach full size.

Adult
Adults reach full body size and sexual maturity, with the species' mature coat and build. Sexual dimorphism — differences in size, mane, horns, or markings — is pronounced in some mammals and subtle in others.
Senior
Senior animals show aging signs such as graying fur, reduced activity, and a greater need for veterinary monitoring of joints, teeth, and organ function. Lifespan and the onset of old age vary widely by species and size.
Color & pattern variants
Natural variants occur in the wild; selectively bred (man-made) variants were developed in captivity.
Adaptable to apartments or houses provided daily exercise needs are met. Needs 1-2 hours of vigorous activity daily — brisk walks, fetch, structured play, or dog sports. Secure fencing is recommended; this is a strong, agile dog. Not suited to being left alone outdoors all day; thrives indoors as part of the family.
Diet
Feed a high-quality complete diet appropriate to a muscular, active medium dog; measure portions to maintain lean condition as the breed builds muscle easily but can become overweight if overfed. Watch caloric intake during lower-activity periods. No unusual breed-specific dietary requirements, but monitor for food sensitivities and skin allergies.
Behavior & temperament
Affectionate, courageous, and devoted — often called a 'velcro' dog toward its people. Highly trainable, eager to please, and food-motivated, responding best to positive, consistent training. High energy and intelligence mean it needs mental and physical stimulation. Good with children when raised together; early, ongoing socialization is essential. Dog-to-dog tolerance varies by individual and some may show same-sex aggression, so supervised introductions are advised.
Health
Generally robust but predisposed to hip dysplasia, elbow dysplasia, hereditary cerebellar ataxia (a known DNA-testable neurodegenerative condition in the breed, NCL-A), and cardiac disease. Also prone to cutaneous/skin allergies, demodectic mange, and some autoimmune conditions. Recommended screening: OFA/PennHIP hips, elbow evaluation, cardiac exam, and DNA test for cerebellar ataxia. Buy from breeders who health-test parents.
Tips, DIY & hacks
Coat is short, stiff, and glossy — minimal grooming; weekly brushing and occasional baths suffice. Moderate, year-round shedder. Prioritize early socialization and reward-based obedience to channel intelligence and prevent boredom-driven behaviors. Be aware of breed-specific legislation (BSL) in some jurisdictions and insurance restrictions. A strong, fenced yard and a job to do (training, dog sports, scent work) keep this breed happy.
