Black Lab Australian Shepherd Mix: The Complete Borador Breed Guide
Everything about the black Lab Australian Shepherd mix (Borador): size, temperament, coat types, health risks, cost.
What Is a Black Lab Australian Shepherd Mix?
The black Lab Australian Shepherd mix — commonly called a Borador or Lab Aussie mix — is a designer crossbreed that pairs two of America's most popular working dogs: the Labrador Retriever and the Australian Shepherd. When breeders specifically select a black-coated Labrador for the pairing, the result is a striking dog that often inherits the Lab's sleek dark coat alongside the Aussie's intelligence and herding instincts.
This is not a recognized breed by the American Kennel Club. It's a first-generation or multigeneration cross, meaning individual puppies can look and behave very differently — even within the same litter. If you're researching this mix, the single most important thing to understand is that predictability is limited. You're getting a dog shaped by two powerful genetic lines, and which traits surface in any given puppy is partly a roll of the dice.
Parent Breed Breakdown: Labrador Retriever Meets Australian Shepherd
Understanding a Borador starts with understanding the two breeds behind it. Both parents are working dogs with deep drives, but they channel that energy differently.
| Trait | Labrador Retriever | Australian Shepherd |
|---|---|---|
| AKC Group | Sporting | Herding |
| Weight Range | 55–80 lb (25–36 kg) | 40–65 lb (18–29 kg) |
| Height | 21.5–24.5 in (55–62 cm) | 18–23 in (46–58 cm) |
| Energy Level | High — needs 60+ min/day | Very high — needs 90+ min/day |
| Coat Type | Short, dense double coat | Medium-length, wavy double coat |
| Shedding | Heavy, seasonal blowout | Moderate-heavy, seasonal blowout |
| Trainability | Excellent — eager to please | Excellent — independent thinker |
| Prey/Herding Drive | High prey drive (retriever instinct) | High herding drive (nipping, circling) |
| Lifespan | 11–13 years | 12–15 years |
| Stranger Friendliness | Very friendly | Reserved, loyal to family |
The Lab contributes a softer mouth (retrieving instinct), a love of water, and an easygoing social nature. The Aussie contributes sharper environmental awareness, a stronger protective streak, and the tendency to "herd" moving objects — including children and other pets. A black Lab Australian Shepherd mix can land anywhere on this spectrum.
Generations Explained: F1, F1B, F2, and Multigen Boradors
- F1 (First Generation): One purebred Lab × one purebred Aussie. Maximum genetic diversity but highest trait variability. Puppies in the same litter may look dramatically different.
- F1B (First-Generation Backcross): An F1 Borador bred back to one of the parent breeds (usually the Lab). This skews traits toward the backcross parent — for example, an F1B backcrossed to a Lab will likely have a shorter coat and stockier build.
- F2 (Second Generation): Two F1 Boradors bred together. More variability than F1B, but some trait stabilization begins. Recessive traits (like merle coloring or dewclaws) may surface.
- Multigen (F3+): Multiple generations of Borador-to-Borador breeding. Traits become more predictable, but the gene pool remains narrow since the mix is relatively new. True multigen Boradors are rare — most breeders are still producing F1 or F1B litters.
For the black Lab Australian Shepherd mix specifically, most puppies you'll encounter are F1 crosses. Dedicated multigen Borador breeding programs are uncommon, so expect significant variation. A responsible breeder will tell you exactly which generation they're producing and show you both parent dogs in person.
Size, Weight, and Build: How Big Will a Borador Get?
Because both parent breeds are medium-to-large dogs, the Borador's size range is narrower than some designer mixes — but still not guaranteed. The Labrador's heavier bone structure can produce a stockier dog, while the Aussie's leaner frame can pull the mix toward a more athletic build.
| Measurement | Minimum (Aussie-leaning) | Average | Maximum (Lab-leaning) |
|---|---|---|---|
| Weight | 40 lb (18 kg) | 55–65 lb (25–29 kg) | 80 lb (36 kg) |
| Height at Shoulder | 18 in (46 cm) | 20–22 in (51–56 cm) | 24.5 in (62 cm) |
| Body Type | Lean, agile | Athletic, moderate bone | Stocky, broad-chested |
Males tend toward the upper range; females toward the lower. If you're adopting an adult Borador from a rescue, you'll know the exact size. If you're getting a puppy, ask the breeder for the parents' weights — the puppy will almost always fall between the two.
Coat, Color, and Shedding: What to Expect
The "black" in black Lab Australian Shepherd mix refers to the dominant black coat many of these dogs inherit from the Lab parent. However, coat genetics are more nuanced than a single color gene.
Coat type possibilities:
- Short and dense (Lab-dominant): Sleek, water-resistant topcoat with a soft undercoat. Easier to groom but still sheds heavily during seasonal changes.
- Medium-length with wave (Aussie-dominant): Longer fur around the neck, chest, legs, and tail. May have a slight wave or feathering. Requires brushing 3–4 times per week to prevent matting behind the ears and in the "britches" (rear leg fur).
- Blended coat: Most Boradors land here — slightly longer than a Lab's coat but shorter than a full Aussie coat. Moderate maintenance.
Color variations: Even when one parent is a black Lab, puppies can inherit the Aussie's merle gene, producing black merle patterns (gray marbling with black patches). You may also see solid black, black-and-white, black-and-tan, or tricolor (black, white, and copper points). Eye color varies from brown to blue — including heterochromia (two different-colored eyes), which is common in merle Aussies and can appear in the mix.
No. Neither parent breed is low-shedding or hypoallergenic. The Lab is one of the heaviest shedders in the dog world, and the Aussie is a moderate-to-heavy shedder with a pronounced seasonal "blow" where they lose their entire undercoat over 2–3 weeks, typically in spring and fall. If you have dog allergies or a strict no-hair household, this mix is not a good fit. Expect year-round shedding with intense seasonal peaks.
Temperament: The Best-Case and Challenging Scenarios
The Borador's temperament is where the mix truly shines — and where it can go sideways if the dog doesn't get adequate mental and physical stimulation. Here's what the range looks like:
✓ Best-Case Temperament
- Highly trainable — picks up commands in 5–10 repetitions
- Socially confident with people and other dogs
- Lab-like eagerness to please combined with Aussie problem-solving
- Excellent with children when socialized early (8–16 weeks)
- Natural affinity for water and retrieving games
- Alert without being excessively vocal
⚠ Challenging Scenarios
- Aussie herding drive directed at children — nipping heels, circling, body-blocking
- Destructive behavior if under-exercised (chewing drywall, destroying furniture)
- Leash reactivity toward other dogs if socialization was incomplete
- Resource guarding (food, toys, people) — more common in Aussie-leaning individuals
- Separation anxiety — both parent breeds bond intensely and can struggle when left alone 6+ hours
- Chasing wildlife, cars, or bikes if recall training isn't rock-solid
The herding instinct is the trait that surprises most first-time Borador owners. An Aussie-leaning Borador may try to herd your toddlers, your cats, or the neighbor's dog through the fence. This isn't aggression — it's hardwired behavior. You can redirect it with structured activities (fetch, agility, herding trials) but you cannot train it away entirely.
Training approach: Use only positive reinforcement and force-free methods. Both breeds are sensitive and intelligent — harsh corrections or aversive tools like shock collars and prong collars damage trust and can trigger fear-based reactivity. A front-clip harness (like the Ruffwear Front Range) paired with high-value treats and clicker training produces the best results. Plan for at least 15–20 minutes of focused training sessions daily, especially during the first two years.
Health Considerations: Hybrid Vigor vs. Reality
One of the most persistent myths about designer dogs is that crossbreeding automatically eliminates health problems through "hybrid vigor." Here's what the science actually says: while mixed-breed dogs can benefit from a broader gene pool, they still inherit every genetic risk carried by both parent breeds. The Merck Veterinary Manual notes that many hereditary conditions are shared across multiple breeds, meaning a cross doesn't escape them — it simply reshuffles the odds.
| Condition | Inherited From | Prevalence | Screening Test |
|---|---|---|---|
| Hip Dysplasia | Both breeds | ~12% of Labs, ~6% of Aussies (OFA data) | OFA/PennHIP radiograph ($200–$400) |
| Elbow Dysplasia | Primarily Lab | ~11% of Labs | OFA elbow radiograph |
| Progressive Retinal Atrophy (PRA) | Both breeds | Carrier rate ~5–8% in Aussies | DNA test ($65–$150 via Embark or Paw Print Genetics) |
| MDR1 Gene Mutation | Australian Shepherd | ~32% of Aussies are affected or carriers | DNA test — critical before any medication administration |
| Exercise-Induced Collapse (EIC) | Labrador Retriever | ~35% of Labs are carriers | DNA test |
| Epilepsy (Idiopathic) | Both breeds | Higher than average in both breeds | No screening test — diagnosis by exclusion |
Approximately one-third of Australian Shepherds carry a mutation in the MDR1 (multi-drug resistance) gene. Dogs with this mutation can have severe, potentially fatal reactions to common medications including ivermectin (found in some heartworm preventives), loperamide (Imodium), and certain sedatives. If your Borador inherits this gene from the Aussie parent, standard doses of these drugs can cause neurological toxicity. Ask your veterinarian about MDR1 DNA testing before any medical procedure. The test costs roughly $65–$80 and can be done with a cheek swab at home.
Other health notes: Both breeds are prone to obesity if overfed and under-exercised. Labs in particular are notorious food-motivated eaters — the AKC notes that a gene variant linked to hunger is present in roughly 25% of Labs. Monitor your Borador's body condition score (BCS) and aim for a lean 4–5 out of 9 on the standard BCS scale. Annual vet checkups should include weight monitoring, and joint supplements (glucosamine/chondroitin, 500–1000 mg daily for a 60 lb dog) may be recommended starting at age 5–6. Always consult your veterinarian before starting any supplement regimen.
Grooming and Daily Care Requirements
Your Borador's grooming schedule depends entirely on which coat type they inherit:
- Lab-dominant coat: Brush 2–3 times per week with a slicker brush or rubber grooming mitt. Use an undercoat rake (like the Furminator deShedding tool) during seasonal blowouts to manage the volume of loose fur. Baths every 6–8 weeks or as needed — over-bathing strips the natural oils that keep the coat water-resistant.
- Aussie-dominant coat: Brush 3–4 times per week, paying special attention to feathering behind the ears, under the legs, and the rear "britches" where matting occurs first. A pin brush followed by a metal comb works well. Professional grooming every 8–10 weeks ($50–$80 per session) can keep feathering trimmed and manageable.
- Nail trims: Every 2–3 weeks regardless of coat type. If you hear clicking on hard floors, they're overdue.
- Ear care: Check weekly. Labs are prone to ear infections due to their floppy ears trapping moisture — especially after swimming. Clean with a veterinary ear wash (e.g., Epi-Otic Advanced) once a week if your dog swims regularly.
- Dental: Daily brushing with enzymatic dog toothpaste, or at minimum dental chews approved by the Veterinary Oral Health Council (VOHC). Both breeds have average dental disease risk.
Cost: What You'll Pay for a Black Lab Australian Shepherd Mix
Because the Borador isn't a rare designer breed like a Bernedoodle or Cavapoo, pricing is more moderate — but still significant when you factor in responsible breeding practices.
| Expense | Low End | Average | High End |
|---|---|---|---|
| Puppy Purchase (from breeder) | $500 | $800–$1,200 | $1,500+ |
| Adoption/Rescue Fee | $150 | $250–$400 | $500 |
| First-Year Veterinary Costs | $600 | $900–$1,200 | $1,800+ |
| Annual Food (quality kibble) | $480 | $600–$800 | $1,000+ |
| Pet Insurance (annual premium) | $400 | $600–$800 | $1,200 |
| Training (group classes) | $150 | $250–$400 | $800+ (private sessions) |
Breeder vs. rescue: Boradors appear in breed-specific rescues (Lab rescues and Aussie rescues) more often than you might expect, particularly when owners underestimate the exercise requirements. Check Petfinder and local breed rescues before committing to a breeder. If you go the breeder route, insist on seeing OFA hip/elbow certifications for both parents, MDR1 and PRA DNA test results, and a contract with a health guarantee and take-back clause. Avoid any breeder who can't produce these documents or who has multiple litters available simultaneously — these are red flags for backyard breeding operations.
Who Is the Black Lab Australian Shepherd Mix Right For?
After years of seeing these dogs in homes and hearing from owners at every experience level, here's my honest assessment of who thrives with a Borador — and who should look elsewhere.
✓ Great Fit For:
- Active families who hike, run, or spend time outdoors daily
- Homes with a securely fenced yard (minimum 4-foot fence — Aussies can climb, and Labs can dig under)
- Owners with prior experience handling high-energy working breeds
- Families interested in dog sports: agility, dock diving, flyball, obedience trials
- Households with older children (8+) who can participate in training and exercise
- People who work from home or can arrange midday exercise — these dogs don't do well crated for 8+ hours
✗ Poor Fit For:
- Apartment dwellers without reliable access to outdoor space
- First-time dog owners unfamiliar with herding/retrieving drives
- Families with toddlers — the nipping/herding risk is real and requires experienced management
- People who work long hours away from home without a dog walker or daycare plan
- Anyone wanting a low-maintenance, low-shedding companion
- Sedentary households — this dog will develop behavioral problems without 60–90 minutes of daily structured activity
The black Lab Australian Shepherd mix is a dog that rewards investment. Put in the training hours, the exercise commitment, and the socialization work during those critical early months, and you'll have a deeply loyal, capable, and joyful companion. Skip those steps, and you'll have an anxious, destructive dog that's too much for most households to manage. Be honest with yourself about your lifestyle before committing.
Frequently Asked Questions
What two breeds make up the black Lab Australian Shepherd mix?
A purebred Labrador Retriever (specifically a black-coated Lab) and a purebred Australian Shepherd. The result is a first-generation (F1) crossbreed sometimes called a Borador. Some breeders produce F1B or multigen versions, but F1 is most common.
How big will a black Lab Australian Shepherd mix get?
Most adults weigh between 50 and 70 lb (23–32 kg) and stand 19–23 inches (48–58 cm) at the shoulder. However, the full range spans 40–80 lb (18–36 kg) depending on which parent's genes are more dominant. Males are typically larger.
What will the temperament be like?
Expect a highly intelligent, high-energy dog that bonds closely with its family. The Lab side contributes friendliness and eagerness to please; the Aussie side adds alertness, independence, and herding instincts. Individual temperament varies significantly — some are social butterflies, others are one-family dogs who are aloof with strangers.
Is the black Lab Australian Shepherd mix hypoallergenic or low-shedding?
No. Both parent breeds are moderate-to-heavy shedders with double coats. Expect year-round shedding with intense seasonal coat blows in spring and fall. This mix is not suitable for allergy sufferers.
What health issues might this mix inherit?
The most significant shared risks are hip dysplasia, elbow dysplasia, progressive retinal atrophy (PRA), idiopathic epilepsy, and the MDR1 drug sensitivity gene (from the Aussie side). Responsible breeders screen for all testable conditions. Ask for OFA certifications and DNA test results before purchasing a puppy.
How much does a black Lab Australian Shepherd mix cost?
From a breeder, expect to pay $800–$1,500 for a puppy from health-tested parents. Adoption through a breed rescue typically costs $150–$500. First-year total ownership costs (including vet care, food, supplies, and training) typically run $2,000–$3,500.
Do Boradors get along with cats and other dogs?
With proper socialization during the 8–16 week critical window, many Boradors coexist well with other pets. However, the Aussie herding instinct can manifest as chasing or nipping cats, and the Lab's prey drive may trigger chasing small animals. Always supervise initial introductions and use positive reinforcement to reward calm behavior around other species.
How much exercise does a black Lab Australian Shepherd mix need?
Plan for a minimum of 60–90 minutes of structured exercise daily — and that's a floor, not a ceiling. This should include a mix of physical activity (running, fetch, swimming) and mental stimulation (training sessions, puzzle toys, scent work). A tired Borador is a well-behaved Borador. A bored one will find its own entertainment, usually at the expense of your belongings.
