At a glance
The Miniature American Shepherd is a scaled-down Australian Shepherd — a compact, merle-or-solid herding dog developed in the United States and popular with the horse-show crowd. Minis are bright, biddable and energetic, excel at agility and obedience, and adapt well to city life provided they get real daily exercise and something to think about. The breed shares several inherited conditions with the Aussie, so ask about MDR1, eye and hip testing.

Health
This page is general information compiled from published sources. It is not veterinary, legal or purchase advice. Dogs vary within a breed — talk to a vet or a reputable breeder about the dog in front of you.
Health notes are not veterinary advice. Conditions listed are those reported for the breed, not a diagnosis of any dog. Always consult a veterinarian.
General health screening
The kennel-club pages consulted do not single out breed-specific conditions; ask your vet about routine screening (hips, eyes, heart) appropriate to a dog of this size.
Hip dysplasia
Commonly reported in the breed; breeders screen hips by X-ray. Ask your vet about hip screening and about keeping your dog lean and fit.
Progressive retinal atrophy (PRA)
An inherited eye condition reported in the breed; DNA tests and eye examinations are available. Ask your vet or breeder about eye screening.
MDR1 drug sensitivity
MDR1 gene mutation (sensitivity to certain drugs) is reported in the breed; a DNA test is available. Tell your vet before any medication is prescribed.
Cataracts
Hereditary cataracts are reported in the breed. Ask your vet about eye examinations if you notice cloudiness in the eyes.
Behaviour
Bright, devoted, quick to learn
The CKC describes the breed as versatile, enthusiastic and quick to learn — a protective, good-natured, devoted and loyal companion that excels at agility, flyball, obedience, therapy work and herding; the AKC says it is intelligent, willing to please and highly trainable, reaching its best as a companion when taught at least basic obedience.
Adaptable, but needs a job
The AKC says Minis are active and athletic but very adaptable to their family's way of life, doing well as city dogs as long as owners provide sufficient exercise and outings that occupy both mind and body; the Royal Kennel Club puts the exercise need at 1–2 hours a day.
Energy and exercise
Energy level is rated 5/5 (very high) on the AKC breed-trait chart. The Royal Kennel Club puts its exercise need at "between 1-2 hours per day".
Training and barking
AKC trait chart: trainability 5/5, barking level 3/5. Individual dogs vary; early socialisation and reward-based training are recommended for every breed.

What owners say
Owner advice is quoted from public community posts and reflects those owners' opinions, not PocketPaw's position. It is unverified and not a substitute for professional advice. Each item links to where it was said.
“The parent club's health page lists the tests it requires of breeders — hip X-rays, annual eye exams, and DNA tests for prcd-PRA, MDR1 drug sensitivity, HSF4 cataracts and NAD — plus recommended elbow, patella, CEA, DM and IVDD/chondrodystrophy screening, and asks that results be submitted to OFA for the CHIC programme so that buyers can look up a litter's parents.”
