Miniature American Shepherd
Also called Mini American, Mini Aussie, Miniature Australian Shepherd
The Miniature American Shepherd is a smart, athletic herding dog that weighs 20 to 40 lb (9 to 18 kg) and looks like a small Australian Shepherd. Minis are loyal, eager to learn and happy to join any activity, but they need daily exercise, mental work and regular brushing.

Personality
Miniature American Shepherds are bright, lively and deeply attached to their people. The AKC describes them as self-motivated workers and endearingly loyal companions, and most Minis want to be wherever the action is: on the trail, beside the horse trailer or underfoot in the kitchen.
Intelligence is both their charm and their challenge. A Mini that is not given something to do will invent a job, and the results, such as nipping at heels, barking at passing cars or rearranging the laundry, are rarely what you would choose. Many herding dogs also try to round up children and other pets, so gentle guidance early on helps.
With family they are affectionate and playful, and the AKC rates them highly with children and other dogs. Toward strangers they tend to be friendly but watchful, and the breed standard allows a reserved look. Socialize your puppy widely and keep the training upbeat. Minis are sensitive and quick, so they respond best to patient, consistent handling and plenty of praise.
History
Despite the old "Australian" label, this is an all-American breed. It started in the 1960s, when breeders took small Australian Shepherds that were working the rodeo circuit and selectively bred them to be smaller still. Early on the dogs were called Miniature Australian Shepherds, and many owners still use that name.
Their size, brains and loyalty made them ideal travelers, and they became especially popular with equestrians who hauled horses to shows. That popularity helped the breed spread across the country. By the mid-1970s the dogs had reached roughly today's size, according to Wikipedia's account of the breed.
In 2011 the AKC chose the Miniature American Shepherd Club of the USA as the parent club for the newly named breed, and in 2015 it gave the Mini full recognition in the Herding Group. The name change from "Miniature Australian Shepherd" was a compromise that not everyone in the breed community loved, but it is the AKC's official name today.
Appearance, coat & colors
A Mini looks like an Australian Shepherd scaled down. Males stand 14 to 18 in (36 to 46 cm) at the shoulder and females 13 to 17 in (33 to 43 cm), and the AKC lists weight as 20 to 40 lb (9 to 18 kg). The body is slightly longer than tall, with moderate bone, a level back and a smooth, agile stride.
The head is clean-cut and in proportion to the body, with an alert, attentive expression. The eyes can be brown, blue, hazel, amber or any mix, sometimes flecked or marbled, which is part of the breed's charm. The tail may be a natural bobtail or may be left long, and in some dogs it is docked.
The coat is medium in length, straight to wavy and weather resistant, with a moderate mane and frill that are more pronounced in males. The AKC recognizes four base colors: black, blue merle, red and red merle. Tan points and white markings appear on many dogs. Merle dogs show marbling, flecks or blotches in any amount.
Training
Minis rate at the very top of the AKC scale for trainability, and they typically learn new cues quickly. That speed works in both directions, though: bad habits stick just as fast, so be deliberate about what you reward.
Start with early socialization and a puppy class, which the AKC recommends for the breed, and make sure your dog learns at least basic obedience. Follow with short, varied sessions that include movement and problem solving. Reward-based methods suit this sensitive, eager breed far better than corrections.
Because many Minis have a strong urge to herd, teach "leave it", a solid recall and a calm settle early. Practice around bikes, children and traffic, which can trigger chasing. Channel the drive into a sport. Minis do well in agility, obedience, tracking and herding trials, and trick training suits dogs who live in smaller homes. A crate routine, like the one in our crate training guide, also helps a clever, busy dog learn to switch off.
Exercise
Mini American Shepherds are active and athletic. The AKC's own text calls their exercise need moderate, but it rates energy and mental stimulation at the top of its scale. Read that as a dog who needs a real daily outlet, not a couple of laps around the block.
Good options include brisk walks or runs, fetch, hiking, agility practice and games that make the dog think. They enjoy outings that occupy mind and body together, such as a trail with scent games or a training session at the park. Puzzle feeders and learning new tricks can fill gaps on bad-weather days.
Fenced, safe areas are best for off-leash play, since herding instincts and sharp senses can send a Mini after anything that moves. Keep a young puppy's activity gentle and avoid hard repetitive jumping until growth finishes. Our guide to how much exercise a dog needs explains how to scale activity by age. A tired Mini is a calm and affectionate housemate. An under-exercised one may bark, nip or dig.
Grooming
Minis have a double coat with a longer outer layer and a woolly undercoat, and they shed a fair amount, even more once or twice a year during shedding season. Brush weekly the rest of the year and daily when the coat is blowing. A deshedding tool or undercoat rake handles the heavy weeks, and a slicker brush or metal comb works out mats and tangles.
Pay attention to the areas that tangle most: behind the ears, the feathering on the back of the legs, the britches and the tail. Bathe only when your dog is dirty, using a gentle dog shampoo. The standard allows light trimming on the ears, feet, hocks and tail, but double coats are generally best left unshaved unless your vet advises otherwise.
Trim nails regularly because overly long nails make walking uncomfortable, and brush the teeth several times a week. Check the ears after swimming or muddy outings. Expect hair on clothes and furniture all year.
Feeding
A Mini does well on a high-quality commercial diet, or a home-prepared one your veterinarian has approved, matched to age: puppy, adult or senior. Fresh water should always be available.
The AKC notes that some Minis tend to put on weight, so measure meals and count training treats toward the daily total. Treats are useful for a food-motivated, trainable dog, but a day of generous rewards can easily add up. Use our dog food calculator for a starting amount and then adjust based on how your dog looks and feels. You should be able to feel the ribs under a light covering, and a visible waist from above.
Active dogs that run, herd or compete may need more food than couch-bound ones, while a spayed or neutered adult who lazes around needs less. Ask your vet which puppy food and feeding plan suit your dog during growth. Puzzle feeders and snuffle mats slow eating and give a bright dog something to do with the meal.
Health
The AKC describes Miniature American Shepherds as generally healthy and notes that responsible breeders test their dogs. Several of the tests relate to conditions seen in Australian Shepherds and in herding breeds generally.
One is multidrug sensitivity, caused by a change in the MDR1 gene. Washington State University lists miniature Australian shepherds among the herding breeds in which the mutation is common, and affected dogs can react badly to certain medications. Test your dog or ask your breeder for results, tell every veterinarian the status, and never give any medication, including over-the-counter ones, without veterinary advice.
The parent club also requires tests for hip dysplasia, eye disease, progressive retinal atrophy, hereditary cataracts and neuroaxonal dystrophy, an inherited neurological condition. Optional tests include elbows, patellas, collie eye anomaly and degenerative myelopathy.
Beyond genetics, keep your Mini lean, brush its teeth and schedule regular checkups. Call your vet if you notice vision changes, such as bumping into objects in dim light, or any stumbling, weakness or tremors.
Health conditions to know about
- Multidrug sensitivity (MDR1) — Inherited gene change that can make some common medications dangerous; a DNA test shows your dog's status.
- Hip dysplasia — Inherited hip joint malformation; parents should have a hip evaluation on record.
- Hereditary cataracts (HSF4) — Inherited cloudiness of the eye lens seen in Australian Shepherd-type dogs; DNA test available.
- Progressive retinal atrophy (PRA-prcd) — Inherited retinal degeneration that leads to vision loss; DNA test available.
- Neuroaxonal dystrophy (NAD) — Inherited neurological disease; the parent club requires a DNA test for breeding dogs.
Health tests to ask a breeder about
- Hip evaluation (OFA or PennHIP)
- Annual eye exam by a veterinary ophthalmologist
- MDR1 DNA test
- HSF4 hereditary cataract DNA test
- PRA-prcd DNA test
- NAD DNA test
- Elbow evaluation (recommended)
- Patella evaluation (recommended)

Living with a Miniature American Shepherd
Minis are flexible about housing but not about attention. The AKC notes they do well as city dogs as long as their owners provide enough exercise, and they make good travel companions. A fenced yard helps, though it is no substitute for walks and training.
Because they are devoted and highly intelligent, many Minis dislike spending long days alone. Without enough company or activity, expect barking, destructive chewing or restless pacing. If you work long hours, plan for a dog walker, daycare or a midday break, and teach your dog to relax in a crate or pen.
The double coat copes well with cooler weather, but hard exercise in the heat calls for shade, water and common sense. They get along with considerate children and other dogs, though herding dogs may nip heels or chase running kids. Early training and supervision handle that. They suit people who see their dog as a teammate for hiking, sports or travel, and they are a poor match for anyone who wants a decorative pet.
Puppies, breeders & rescue
Choose a breeder who tests, and confirm it in writing. The Miniature American Shepherd Club of the USA requires, for its CHIC and breeder programs, a hip evaluation, an annual eye exam by a veterinary ophthalmologist, and DNA tests for progressive retinal atrophy (PRA-prcd), MDR1, hereditary cataracts (HSF4) and neuroaxonal dystrophy. The club also recommends elbow and patella evaluations and several additional DNA tests. Ask which of these were completed on both parents, and see the results.
The naming is confusing, and you will see "Mini Aussie", "Toy Aussie" and "Miniature Australian Shepherd" in ads. Whatever the label, ask which registry the puppies are in and see the parents' health results. Good breeders raise puppies in the home, introduce them to many experiences and screen buyers as carefully as you screen them.
Prices vary widely, so compare the whole package rather than the number. Adults and young dogs occasionally appear in breed rescues, including the one the parent club lists.
Miniature American Shepherd FAQ
How big do Miniature American Shepherds get?
Males stand 14 to 18 in (36 to 46 cm) and females 13 to 17 in (33 to 43 cm). The AKC lists weight as 20 to 40 lb (9 to 18 kg).
What is the difference between a Miniature American Shepherd and an Australian Shepherd?
Mostly size and history. The Mini is a smaller dog that came from small Australian Shepherds, and the AKC recognizes it as its own breed. Temperament and looks are similar, so see our Australian Shepherd profile for comparison.
Are Miniature American Shepherds good apartment dogs?
They can be, if you meet their exercise and mental needs every day. The AKC says they do well as city dogs when owners provide enough activity, but a bored Mini may bark or chew.
What is MDR1 and does my Mini need a test?
MDR1 is an inherited gene change that can make dogs react badly to certain drugs. Herding breeds including miniature Australian shepherds often carry it, and the parent club requires testing for breeding dogs. Ask your vet about testing.
Do Miniature American Shepherds shed a lot?
Yes. The AKC says they shed a fair amount, with heavier seasonal shedding once or twice a year. Weekly brushing, and daily brushing in shedding season, keeps it manageable.
