Owner Fit & Decision Guide

Owner Match

TraitAustralian TerrierScottish Sheepdog Longhair
Experience LevelBeginner (with conditions)Beginner
First-Time Owner

  • Have pocket pets (hamsters, rats) that roam
  • Want a dog that can be off-leash in unfenced areas
  • Unwilling to manage potential dog-aggression
  • Passive or permissive owner (if you treat them like a baby, they will become a tyrant)

Scottish Sheepdog Longhair Dealbreakers

  • Cannot tolerate barking
  • Want a 'wash and go' dog - grooming is a hobby here
  • Want a dog to jog 10 miles with you in July
  • Use harsh training methods - they are 'soft' dogs that shut down

Training

Australian Terrier

MethodPositive reinforcement only
Repetitions to Learn15-25
Challenges
The 'What's in it for me?' factor - they are intelligent but independentRepetitive drilling bores themOff-leash recall is unreliable - if a squirrel runs, the Aussie follows
Tips
  • Harsh methods trigger their 'terrier grit,' causing them to shut down or fight back
  • Use high-value rewards (food/toys)
  • Keep training sessions short and varied
  • Practice 'Nothing in Life is Free' to maintain household boundaries

Scottish Sheepdog Longhair

MethodPositive reinforcement only
Repetitions to Learn<15
Challenges
Can get bored with endless repetitionSensitive to handler emotion - if you're frustrated, they disengage
Tips
  • Keep sessions short (5-10 mins) and fun
  • Harsh corrections will cause them to shut down or become fearful
  • They are intelligent but not 'neurotic' about problem-solving like Border Collies
  • Train 'quiet' command early to manage barking

Australian Terrier Considerations

dealbreakerThe Alarm System That Won't Quit

Bred to alert settlers to snakes and intruders, they score 5/5 on watchdog ability. In modern settings, this means barking at delivery trucks, hallway footsteps, and leaves blowing across the patio. Often a dealbreaker for renters with noise restrictions.

dealbreakerSame-Sex Aggression

Documented risk of aggression toward dogs of the same sex, particularly between two females. This often emerges at sexual maturity (18-24 months) and can escalate from posturing to serious fighting. They generally do best as the only dog or with a companion of the opposite sex.

dealbreakerPredatory Fixation

Their prey drive is not a game; it is a job. They were engineered to kill rats and snakes. They cannot be trusted with hamsters, rabbits, or guinea pigs, and they may harass cats that run. This is a Full Predatory Sequence breed—they do not just chase; they grab and shake.

Scottish Sheepdog Longhair Considerations

dealbreakerThe Recreational Barker

Bred to communicate with shepherds over long distances, Collies alert to everything: delivery trucks, neighbors, squirrels, and wind. Unlike a guard dog's warning bark, a Collie often barks to chat or express boredom. The bark is sharp and piercing.

challengeExtreme Noise Sensitivity

Exceptionally sensitive to their environment. Thunderstorms, fireworks, and even loud arguments can cause significant distress. Poor candidates for chaotic households with constant screaming or slamming doors.

dealbreakerThe Grooming Commitment

The spectacular coat requires weekly 45-60 minute line-brushing sessions. Surface brushing leaves the undercoat to mat, leading to 'felted' dogs that must be shaved - a disaster for double coats. This is a hobby, not a chore.

challengeThe Herding Nip

Young Collies may attempt to herd running children by nipping at heels. This is an arrested predatory sequence behavior, not aggression, but it can be frightening for small children and requires management.

Multi-Species Compatibility

SpeciesAustralian TerrierScottish Sheepdog Longhair
With CatsCaution - safe only if raised together and the cat does not runHigh safety - one of the best large breeds for multi-species homes. Low prey drive.
Small MammalsUnsafe - high risk for hamsters, rabbits, guinea pigs, rodentsGenerally safe - may try to herd but rarely has grab-bite instinct
Birds / ReptilesUnsafe - high riskGood with poultry if trained, though may harass if untrained

Advanced Behavior

BiddabilityMediumHigh
Noise SensitivityLowHigh
Territorial Barking
Same-Sex Aggression Onset18 monthsN/A

Australian Terrier: Full Predatory Sequence: Orient → Eye → Stalk → Chase → Grab-Bite → Kill-Bite. Bred to kill snakes and rats. You cannot 'train out' the desire to shake a rat; you can only manage it. Not 'will to please' dogs - they are 'what's in it for me?' dogs.

Scottish Sheepdog Longhair: Predatory sequence is Orient → Eye → Stalk → (Stop). They may stare at and follow cats but grab-bite is largely inhibited. They WANT to work with you - unlike Huskies who ask 'what's in it for me?' a Collie asks 'what do you want me to do?'

First Year & Life Stages

ChallengeAustralian TerrierScottish Sheepdog Longhair
Puppy Difficulty
Destructive Phase6-186-14
House TrainingMediumEasy
Crate TrainingMediumHigh
Adolescent Regression

Australian Terrier: While small and portable, they are intense. House training is moderately difficult (terriers can be stubborn), and their sharp puppy teeth are used freely during play. Critical socialization window is 8-16 weeks - must socialize to handling and strangers to prevent natural wariness from turning into defensiveness.

Scottish Sheepdog Longhair: Collie puppies are generally polite and observant, easier than Labradors or high-drive breeds. Main challenges are noise sensitivity and socialization to prevent shyness. May need ear taping for classic semi-prick look (cosmetic only).

Australian Terrier Quirks

The Ruff

Distinctive ruff of hair around the neck (like a lion's mane) which was historically protective against snake bites

The Topknot

The soft, silky hair on their head contrasts with the wire body coat and needs gentle combing

Digging for Fun

They don't just dig to escape; they dig for fun. Provide a designated sandpit and bury toys in it to save your flowerbeds.

Bossiness

They will attempt to run the household. 'Nothing in life is free' training is recommended to maintain boundaries.

Scottish Sheepdog Longhair Quirks

The Collie Nose

They use their long nose to poke, prod, and nudge you - their way of holding hands

The Greeter's Grin

Some Collies 'smile' (bare their teeth) when submissive or happy. Looks terrifying to strangers but is a sign of joy.

Air Snapping

May snap the air when excited or playing

The Off Switch

Unlike Border Collies, Rough Collies have a distinct 'off switch' and are often described as couch potatoes indoors

Frequently Asked Questions

Yes, Australian Terriers are affectionate and playful with respectful children, but they won't tolerate rough handling like a Golden Retriever might. They do best in homes with older children who understand how to interact respectfully with dogs.
