Collie/Labrador Retriever Mix: Temperament, Size, and Care Guide

If you've ever watched a Rough Collie glide across a field and then seen a Labrador Retriever barrel joyfully into a lake, you might wonder what happens when you combine the two. The Collie/Labrador Retriever mix — sometimes called a "Collidor" or "Labracollie" — is a designer cross that blends the Collie's sensitivity and herding instinct with the Labrador's outgoing, retrieve-anything-that-moves enthusiasm. The result can be a spectacular family dog, but like all mixed breeds, individual puppies can land anywhere on a wide spectrum of traits.

This guide breaks down what prospective owners actually need to know: realistic size ranges, the coat types you might get, temperament scenarios (both the dream and the challenge), health screenings to demand from breeders, and the real costs involved in 2026. We'll also debunk the hybrid vigor myth so you can make a clear-eyed decision.

The Parent Breeds: What Goes Into a Collie/Labrador Retriever Mix

Before predicting what a mixed puppy might become, it helps to understand the two purebreds behind it. Both breeds are well-documented by the AKC Collie breed standard and the AKC Labrador Retriever standard, giving us solid baseline data.

Parent Breed Comparison

Trait	Rough/Smooth Collie	Labrador Retriever
Weight range	50–75 lb (23–34 kg)	55–80 lb (25–36 kg)
Height at shoulder	22–26 in (56–66 cm)	21.5–24.5 in (55–62 cm)
Original function	Herding (sheep, cattle)	Retrieving (waterfowl, fishing nets)
Coat type	Long double coat (Rough) or short dense coat (Smooth)	Short, dense, water-resistant double coat
Shedding	Heavy seasonal blow-out; moderate year-round	Moderate year-round; seasonal surge
Energy level	Moderate to high; bursts of speed	High; sustained endurance
Trainability	High; sensitive to tone, soft correction	Very high; food-motivated, resilient
Typical lifespan	12–14 years	11–13 years
Known health concerns	Collie eye anomaly (CEA), MDR1 drug sensitivity, dermatomyositis	Hip/elbow dysplasia, exercise-induced collapse (EIC), obesity

Both breeds are biddable and people-oriented, which is why the cross tends to produce dogs that bond closely with their families. But the Collie's herding instinct (nipping, circling, staring) and the Lab's mouthy, high-retrieval drive can show up in unpredictable combinations in mixed puppies.

Understanding Generations: F1, F1B, F2, and Multigen

Unlike Poodle-based designer breeds (Goldendoodles, Labradoodles), the Collie/Labrador Retriever mix does not have a large multigen breeding community. Most available puppies will be F1 crosses from breeders who paired a registered Collie with a registered Labrador. This means you should expect significant puppy-to-puppy variation even within the same litter.

Size, Build, and Physical Variability

Because both parent breeds occupy a similar weight class, the Collie/Labrador Retriever mix tends to be a medium-to-large dog. However, the exact build depends on which parent's frame the puppy inherits.

Expected Size Range for Collie/Labrador Retriever Mix

Measurement	Low End (Lab-leaning)	High End (Collie-leaning)
Adult weight	50 lb (23 kg)	80 lb (36 kg)
Height at shoulder	21 in (53 cm)	26 in (66 cm)
Body style	Stockier, broader chest, shorter muzzle	Leaner, narrower frame, longer snout
Time to full size	12–15 months	14–18 months

Practical note: If you're adopting a puppy and want to estimate adult weight, a common formula is to double the puppy's weight at 16 weeks. For mixed breeds with this much variability, add a ±10 lb (4.5 kg) margin of error. A 20 lb (9 kg) Collie/Lab puppy at 16 weeks could mature anywhere from 30 to 50 lb (14–23 kg), though most will land in the 40–50 lb range given the parent breed averages.

Coat Types, Shedding, and the Hypoallergenic Question

Let's address the most common question upfront: No, the Collie/Labrador Retriever mix is not hypoallergenic. Neither parent breed is low-shedding. Both have double coats that blow seasonally, and this cross will shed regardless of which coat type it inherits.

The coat possibilities break down into three general categories:

• Lab-leaning coat (most common in F1): Short, dense, water-resistant outer coat with a soft undercoat. Moderate year-round shedding with two heavy seasonal sheds (spring and fall). Easy to maintain with weekly brushing using a rubber curry brush or deshedding tool like the Furminator for short hair.
• Collie-leaning coat: Longer outer coat with a thick, woolly undercoat. The full Rough Collie coat may not appear, but you'll often see feathering on the legs, a ruff around the neck, and a plumed tail. Requires brushing 3–4 times per week with a slicker brush and undercoat rake. Expect significant shedding during coat blows.
• Intermediate coat: Medium-length hair that's longer than a Lab's but shorter than a full Rough Collie's. Often seen as a "wavy" or "fluffy" Lab coat. This is the most common outcome in F1 crosses and requires brushing 2–3 times per week.

Smooth Collie genetics can also enter the mix. If the Collie parent is a Smooth Collie (short-coated variety), puppies are far more likely to have Lab-like coats. Ask the breeder which Collie variety was used.

Temperament: Best-Case and Challenging Scenarios

Both Collies and Labradors are renowned family dogs, but their working styles produce very different behavioral tendencies. A Collie/Labrador Retriever mix can inherit any combination of these traits.

Key temperament variables to prepare for:

• Herding instinct: May show up as nipping at heels, circling, or trying to "gather" children and other pets. Typically emerges between 4–8 months of age. Redirect with toy-carrying alternatives and reward calm behavior around moving targets.
• Retrieval drive: Most Collie/Lab mixes will want to carry objects. Channel this into fetch, nosework, and carrying a backpack on walks rather than letting it become destructive chewing.
• Sensitivity vs. resilience: Collies tend to shut down with harsh corrections, while Labs tend to bounce back. Your mix could land anywhere on this spectrum. Default to force-free, positive reinforcement methods — reward-based training works excellently with both parent breeds.
• Vocalization: Collies are more vocal than Labs (barking at stimuli, "talking"). If your mix inherits this trait, expect alert barking that needs training management, especially in apartments or close-neighborhood settings.
• Separation tolerance: Both breeds are prone to separation distress when under-exercised and under-stimulated. Plan for crate training, enrichment toys (Kong, puzzle feeders), and gradual alone-time conditioning from puppyhood.

Health Considerations: Hybrid Vigor vs. Reality

One of the most persistent myths in the designer dog world is that mixed breeds automatically enjoy "hybrid vigor" — the idea that crossing two breeds eliminates inherited health problems. The reality is more nuanced.

Hybrid vigor (heterosis) is a real genetic phenomenon, but it primarily applies to traits controlled by many genes with additive effects — things like overall fertility and general vitality. For single-gene or few-gene inherited disorders, a mixed-breed puppy can absolutely inherit conditions from either parent breed. According to research published in the Journal of Veterinary Internal Medicine, mixed-breed dogs do show a modest reduction in some inherited disorder rates, but they are not immune.

Here are the specific conditions you should screen for in a Collie/Labrador Retriever mix:

Health Conditions to Screen For

Condition	Inherited From	Prevalence	Screening Test
Collie Eye Anomaly (CEA)	Collie parent	Estimated 70–90% of Rough Collies are carriers or affected	CERF/OFA ophthalmologist exam; DNA test available
MDR1 drug sensitivity	Collie parent	~75% of Collies carry the mutation	Washington State University MDR1 DNA test
Hip dysplasia	Both parents	~12% of Labs, ~6% of Collies per OFA data	OFA or PennHIP radiographic evaluation
Elbow dysplasia	Labrador parent	~12% of Labs per OFA data	OFA elbow radiographs
Exercise-Induced Collapse (EIC)	Labrador parent	~5–6% of Labs affected; ~30% carriers	DNA test (University of Minnesota)
Progressive Retinal Atrophy (PRA)	Both parents	Variable; DNA tests available for prcd-PRA	CERF exam + DNA panel
Gastric dilatation-volvulus (bloat)	Risk from both (deep-chested breeds)	Lifetime risk ~5–6% in large, deep-chested dogs	No screening test; preventive gastropexy may be discussed with your vet

What responsible breeders should provide: OFA hip and elbow scores for both parents, CERF eye clearance, EIC DNA test results for the Lab parent, MDR1 DNA test results for the Collie parent, and a documented health guarantee. If a breeder cannot produce these clearances, walk away.

Grooming, Exercise, and Daily Care

Grooming by Coat Type

• Short coat (Lab-leaning): Brush weekly with a rubber curry brush. Bathe every 6–8 weeks or as needed. Check and clean ears weekly (Labs are prone to ear infections due to floppy ears trapping moisture). Budget ~$30–$50 per professional grooming session if you opt for occasional deshedding treatments.
• Medium/long coat (Collie-leaning): Brush 3–4 times per week with a slicker brush and undercoat rake. During seasonal coat blows (typically spring and fall, lasting 2–4 weeks), daily brushing is necessary to prevent matting. Professional grooming every 8–10 weeks runs $60–$90 per session depending on your region.
• Nails, teeth, ears: Trim nails every 2–3 weeks (or when you hear clicking on hard floors). Brush teeth 3–5 times per week using a veterinary-formulated enzymatic toothpaste. Both breeds are susceptible to periodontal disease by age 3 if dental care is neglected.

Exercise Requirements

Plan for 60–90 minutes of structured physical activity daily, plus mental enrichment. This is not a dog that thrives on a 15-minute leash walk around the block.

• Physical exercise: Hiking, swimming (most inherit the Lab's love of water), fetch, bike-joring, or off-leash running in secure areas. Aim for at least 30 minutes of sustained aerobic activity.
• Mental stimulation: Puzzle feeders, scent work, trick training sessions (10–15 minutes, 2–3 times daily), herding balls, or structured games like hide-and-seek with toys.
• Puppies under 18 months: Limit forced exercise (running alongside bikes, long jogs) to protect developing growth plates. Free play and short walks are safer. A good rule: 5 minutes of structured walk per month of age, twice daily.

Breeder vs. Rescue Availability

The Collie/Labrador Retriever mix is not among the most common designer crosses. You won't find the volume of breeders that exist for Labradoodles or Goldendoodles. This means:

• Breeder route: Expect waitlists of 2–6 months. Seek breeders who health-test both parent breeds (not just "vet-checked" — ask for OFA numbers you can verify at ofa.org). Reputable breeders will have a take-back clause in their contract and will ask you as many questions as you ask them.
• Rescue route: Collie and Lab mixes appear regularly in shelters and breed-specific rescues. Check Petfinder, the Collie Rescue Foundation, and Lab-specific rescues like Labradors & Friends. Adult dogs from rescue let you see the fully developed temperament and size — a significant advantage with variable mixed breeds.

Who This Mix Suits Best

Frequently Asked Questions

What two breeds make up the Collie/Labrador Retriever mix?

This cross combines a Collie (typically the Rough Collie, though Smooth Collies are sometimes used) with a Labrador Retriever. Both are AKC-recognized breeds with well-documented standards. The mix is not recognized as a breed by the AKC but may be registered with designer breed registries like the ACHC or IDCR.

How big will a Collie/Labrador Retriever mix get?

Most adults fall between 50–80 lb (23–36 kg) and stand 21–26 inches (53–66 cm) at the shoulder. Because both parent breeds are similar in size, there's less extreme variability than you'd see in a cross between, say, a Great Dane and a Beagle. However, the exact build — stocky vs. lean — depends on which parent's frame the puppy inherits.

What will the temperament be like?

Expect an intelligent, people-oriented dog that forms strong family bonds. The specific blend of herding instinct (Collie) and retrieval drive (Lab) varies per individual. Some are calm, biddable companions; others are high-drive working dogs that need jobs. Early socialization (ideally starting at 8–12 weeks) and consistent positive reinforcement training are the strongest predictors of a well-adjusted adult dog.

Is this mix hypoallergenic or low-shedding?

No. Neither the Collie nor the Labrador Retriever carries low-shedding or hypoallergenic coat genetics. All Collie/Lab mixes will shed — the question is how much and how often. Short-coated individuals shed moderately year-round; longer-coated individuals shed heavily during seasonal coat blows. If you need a low-shedding dog due to allergies, this is not the right cross for you.

What health issues might this mix inherit?

The primary concerns are Collie Eye Anomaly, MDR1 drug sensitivity, hip and elbow dysplasia, Exercise-Induced Collapse, and bloat (GDV). Responsible breeders screen both parent breeds for these conditions. Even with health-tested parents, mixed-breed puppies can inherit recessive conditions — hybrid vigor reduces risk modestly but does not eliminate it. Always consult your veterinarian for a breed-appropriate health monitoring plan.

How much does a Collie/Labrador Retriever mix cost?

From a breeder, expect to pay $600–$1,800 for a puppy, depending on the breeder's reputation, health testing, and your region. Adoption through a rescue typically costs $150–$500. First-year total ownership costs (including veterinary care, food, supplies, and training) typically range from $3,100 to $7,600.

Are Collie/Labrador Retriever mixes good with children?

Generally yes — both parent breeds are known for being good with kids. The main caveat is herding behavior: some Collie/Lab mixes will nip at running children's heels or try to "herd" them. This is manageable with training and supervision but means the mix is best suited for families with children old enough to understand how to interact calmly with dogs, or families committed to redirecting the behavior consistently.
