Miniature American Shepherd

Mini American, Miniature Australian Shepherd

The Miniature American Shepherd comes from the United States. The FCI standard describes a small herding dog with strong herding and guardian instincts, intelligent and primarily a working dog, slightly longer than tall, with a medium-length, straight to wavy, weather-resistant coat. Its colours are black, blue merle, red and red merle, with or without white and tan markings, and its eyes may be brown, blue, hazel or amber. PetPrep draws it in blue merle with a natural tail.

PetMD says it has a lot of energy and needs at least one hour of exercise every day, ideally two, along with jobs that keep its mind busy, and that it should be brushed a couple of times a week; the AKC says weekly brushing is enough for most of the year, with daily brushing in the shedding season. The AKC says it can make a great family dog with obedience training and early socialisation, and tends to be good with children but may try to herd them; PetMD adds that its devotion to its family can lead to separation anxiety when it is left alone. PetMD gives its lifespan as 12 to 13 years.

Available in the 12-week PetPrep Challenge (paid breed).

Game rules, not veterinary advice

How PetPrep simulates it

In PetPrep one real week is one month of the pet's life. These are the rules the game uses for this breed. PetPrep chose them from the sources on this page; they are not care instructions for a real animal.

Life stageStartsMeals a dayDaily step goal
Puppyarrives at 2 months4; from month 3: 3; from month 6: 21,000 steps per month of age (2,000 on arrival), up to 6,000 from month 6
Young dogmonth 926,000 steps
Adultmonth 36 (3 years)26,000 steps
Seniormonth 108 (9 years)24,500 steps
  • Step goal = minutes of daily exercise × 100 steps: an adult gets 1 hour, so 6,000 steps a day.
  • Learns commands as fast as the mixed breed of the free plan.
  • Becomes a senior in month 108 (9 years) — the last quarter of the breed's expected lifespan.
  • Walks count real steps from Apple Health or Health Connect (with permission, read-only) and the phone's motion sensor — no GPS.
  • Combing twice a week.

Each game number is a PetPrep decision recorded with its sources. — PetMD, AAHA, Dogs Trust, ASPCA, VCA Animal Hospitals, The Royal Kennel Club, Purdue University Canine Welfare Science, Wikipedia, British Journal of Sports Medicine S10S11S14S18S19S21S24S35S45S269

Health

For information only, not vet-reviewed. Ask your vet about your own animal.

  • Inherited eye diseases occur in the breed, such as collie eye anomaly, cataracts and progressive retinal atrophy. — PetMD S269
  • Hip dysplasia, a poorly developed hip joint that can lead to arthritis, occurs in the breed; breeders are advised to have the parents' hips scored. — PetMD S269
  • Luxating patellas, where the kneecap temporarily slips out of place, occur in the breed. — PetMD S269

Before you buy: what to check with the breeder

Questions to settle before you take a puppy home. The points are advice from vets, welfare charities and kennel clubs; each cites its source.

For every breed

  • See the puppy with its mother, where it was born. — PDSA, RSPCA K1K2
  • The puppy should not leave its mother before 8 weeks of age. — PDSA K1
  • Ask for the pedigree. Under FCI rules a pedigree may be issued for correct parentage only. — FCI K7
  • Ask to see the health-test results of both parents. Which tests matter depends on the breed. — PDSA, British Veterinary Association, FOUR PAWS UK K1K9K10
  • National kennel clubs can set breeding rules that go beyond the FCI's — ask the breed club which tests the parents need. — FCI K7
  • Ask for a written sale contract that records the puppy's background and health. — British Veterinary Association, FOUR PAWS UK K9K10

Laws on the minimum age, microchipping and vaccination differ by country — check the rules where you live.

Health tests of the parents for this breed

Other screening schemes for this breed

  • DNA test for multi-drug sensitivity (MDR1) — PetMD S269
  • Eye examination by a veterinary eye specialist (UK: BVA/KC/ISDS scheme; for some breeds with gonioscopy) — PetMD S269

  • Kneecap check for luxating patella before breeding — PetMD S269

These lists come from the UK's Royal Kennel Club and are an orientation; national kennel clubs can set their own, stricter rules. Ask the breed club and the breeder which tests the parents have done.
