10 Best Medium Sized Hypoallergenic Dogs for Allergy Sufferers
Discover the 10 best medium sized hypoallergenic dogs ranked by allergy-friendliness, temperament, and care needs.
If you're sneezing your way through dog park visits but refuse to give up on the dream of a mid-sized canine companion, you're not alone. Roughly 10–20% of the U.S. population is allergic to dogs, according to the American Academy of Allergy, Asthma & Immunology. The good news? Several medium sized hypoallergenic dogs produce fewer allergenic proteins, making cohabitation far more comfortable — though never completely reaction-free.
This guide ranks 10 medium-sized breeds (roughly 20–60 lb / 9–27 kg) that are widely recognized for low-allergen coats. We'll cover why each breed qualifies, how they compare head-to-head, and how to pick the right one for your household.
How We Selected These Breeds: Our Criteria
Selection Criteria for This List
- Size class: Adult weight between 20–60 lb (9–27 kg) — the "medium" sweet spot that fits apartments and houses alike.
- Coat type: Hair-like coats (not fur) that shed minimally, or curly/wavy coats that trap dander close to the skin.
- Allergen protein profile: Breeds that produce lower levels of Can f 1 and Can f 2 — the primary allergenic proteins found in dog saliva and dander, as identified in peer-reviewed allergy research.
- Temperament & trainability: Breeds suitable for family life, not just low-allergen novelties.
- Availability: Breeds you can realistically find through responsible breeders or breed-specific rescues in North America.
Note: No dog is 100% hypoallergenic. Individual dogs within a breed vary in allergen output. Always spend time with a specific dog before committing.
The 10 Best Medium Sized Hypoallergenic Dogs, Ranked
We've organized these breeds from most allergy-friendly to moderately so, factoring in coat type, shedding behavior, dander production, and real-world owner reports. Each entry includes the breed's size class, standout trait, and a brief profile tailored to allergy-conscious owners.
1. Soft Coated Wheaten Terrier
Size: 35–45 lb (16–20 kg) | Height: 17–19 in (43–48 cm)
Key Allergy Trait: Single-layer, hair-like coat that sheds very minimally and produces low dander dispersal.
The Wheaten is Ireland's lesser-known terrier gem. Its silky, slightly wavy coat traps loose hair rather than releasing it into the environment, which means fewer airborne allergens. They're spirited, affectionate, and famously good with children — a rarity among terriers. Expect moderate grooming: a thorough brushing 3–4 times per week and a professional trim every 6–8 weeks ($50–$75 per session). Their "forever young" temperament means they stay playful well into their senior years (lifespan: 12–14 years).
Why it made the list: Consistently cited by allergists as one of the best-tolerated breeds for sensitive individuals, with a coat that genuinely minimizes environmental allergen spread.
2. Portuguese Water Dog
Size: 35–60 lb (16–27 kg) | Height: 17–23 in (43–58 cm)
Key Allergy Trait: Curly or wavy waterproof coat that sheds almost imperceptibly; low dander output.
Made famous by the Obama family's dogs Bo and Sunny, the Portuguese Water Dog (PWD) was bred to work alongside fishermen — retrieving nets, herding fish, and carrying messages between boats. That working heritage translates to a smart, biddable dog that thrives on having a job. Their tight curls trap dander efficiently, and regular grooming (brushing 2–3x/week, professional clips every 6–8 weeks) keeps allergen levels low. They excel at agility, obedience, and water sports. Lifespan: 11–13 years.
Why it made the list: The PWD's hypoallergenic reputation is backed by real-world allergy-sufferer success stories and a coat structure that genuinely limits allergen dispersal.
3. Schnauzer (Standard)
Size: 30–50 lb (14–23 kg) | Height: 17.5–19.5 in (44–50 cm)
Key Allergy Trait: Wiry double coat with minimal shedding; the outer coat traps loose undercoat hair.
The Standard Schnauzer is the original schnauzer — not a miniaturized or giant version, but the medium-sized prototype from 15th-century Germany. Their wiry, low-shedding coat requires hand-stripping or clipping every 5–8 weeks. They're alert, loyal, and more physically robust than many similarly sized breeds. Standard Schnauzers are excellent watchdogs without being aggressive, and they bond intensely with their families. Lifespan: 13–16 years — one of the longest-lived medium breeds.
Why it made the list: The wiry coat structure is fundamentally different from shedding breeds — loose hair gets caught in the topcoat rather than floating into your environment.
4. Lagotto Romagnolo
Size: 24–35 lb (11–16 kg) | Height: 16–19 in (41–48 cm)
Key Allergy Trait: Dense, curly, wool-like coat that sheds extremely minimally; considered one of the most allergy-friendly purebreds.
Italy's truffle-hunting specialist is a relative newcomer to the U.S. market but is gaining devoted followers. The Lagotto's tight, lamb-like curls are often compared to Poodle coats but with a slightly different texture that many allergy sufferers report tolerating even better. They're intelligent, eager to please, and excel at scent work. Their moderate energy level (45–60 minutes of exercise daily) fits well with active families. Purchase price tends to run $2,500–$4,000 from responsible breeders due to limited U.S. availability. Lifespan: 15–17 years.
Why it made the list: Exceptionally low shedding and dander output, combined with a calm household temperament, make this a top pick for allergy-sensitive homes.
5. Irish Water Spaniel
Size: 45–68 lb (20–31 kg) | Height: 21–24 in (53–61 cm)
Key Allergy Trait: Tight, liver-colored curls with a naturally low-shedding coat; minimal dander dispersal.
The tallest of the spaniels, the Irish Water Spaniel (IWS) is a versatile sporting dog with a clownish personality. Their distinctive "rat tail" and topknot of loose curls make them instantly recognizable. The curly coat sheds very little, though it requires brushing 2–3 times weekly and professional grooming every 6–8 weeks. They're highly trainable but can be stubborn — positive reinforcement methods work best. IWS thrive with active owners who enjoy hiking, swimming, or field sports. Lifespan: 12–14 years.
Why it made the list: The IWS coat structure is remarkably similar to Poodle curls, trapping allergens close to the skin rather than releasing them.
6. Kerry Blue Terrier
Size: 33–40 lb (15–18 kg) | Height: 17.5–19.5 in (44–50 cm)
Key Allergy Trait: Soft, wavy, single-layer coat that sheds minimally; puppies are born black and gradually "clear" to blue-gray.
Ireland's national terrier is a striking dog with a coat that's often described as feeling like human hair. The Kerry Blue's minimal shedding makes it a strong candidate for allergy sufferers, though the coat requires significant upkeep — daily brushing during the first year and professional grooming every 4–6 weeks throughout life. They're spirited, intelligent, and loyal, though they can be dog-selective and benefit from early socialization. Lifespan: 12–15 years.
Why it made the list: A genuinely low-shedding terrier with a coat that many allergy sufferers tolerate well, paired with a versatile temperament.
7. Bedlington Terrier
Size: 17–23 lb (8–10 kg) | Height: 15–17.5 in (38–44 cm)
Key Allergy Trait: Unique linty, curly coat that sheds very little; coat texture traps dander effectively.
With their distinctive lamb-like appearance and arched back, Bedlington Terriers are unmistakable. Originating from northeast England, they were originally bred to hunt vermin and otters. Their coat — a mix of soft and wiry hair — sheds minimally and requires brushing 2–3 times per week with professional trimming every 6–8 weeks. They're gentler and less intense than many terriers, making them suitable for quieter households. Lifespan: 11–16 years.
Why it made the list: The unusual coat texture is exceptionally low-shedding, and their calmer terrier temperament suits allergy sufferers who want a less high-strung companion.
8. Barbet
Size: 35–65 lb (16–29 kg) | Height: 19–24.5 in (48–62 cm)
Key Allergy Trait: Long, curly, woolly coat with minimal shedding; hair grows continuously and traps dander.
France's ancient water dog is a precursor to the Poodle and remains relatively rare outside Europe. The Barbet's curly coat is low-shedding but high-maintenance — expect to brush daily or every other day to prevent matting, with professional grooming every 6–8 weeks ($60–$90 per session). They're calm, friendly, and highly trainable, with a softer temperament than many sporting breeds. Their moderate energy (45–60 minutes of daily exercise) and gentle nature make them excellent family dogs. Purchase price: $2,500–$4,500. Lifespan: 12–14 years.
Why it made the list: A genuinely low-allergen coat combined with an easy-going temperament that suits families with allergy-sensitive members.
9. Poodle (Miniature & Medium/Moyen)
Size: Miniature 10–15 lb (4.5–7 kg); Moyen/Medium 20–35 lb (9–16 kg) | Height: 10–15 in (25–38 cm) for Miniature; 15–20 in (38–51 cm) for Moyen
Key Allergy Trait: The gold standard of hypoallergenic coats — tight curls that trap dander and shed almost nothing.
The Poodle needs little introduction: consistently ranked among the most intelligent dog breeds, highly trainable, and available in multiple sizes. The Moyen (or "medium") Poodle fills the gap between Miniature and Standard, landing squarely in the medium-sized category that many families prefer. Their coat is the benchmark against which other "hypoallergenic" breeds are measured. Grooming is non-negotiable: professional clips every 4–6 weeks ($50–$85) and brushing every 1–2 days. Lifespan: 12–15 years.
Why it made the list: The Poodle's coat is the reference point for hypoallergenic dogs. Including the Moyen size ensures a true medium-sized option.
10. Spanish Water Dog
Size: 30–50 lb (14–23 kg) | Height: 15.75–19.75 in (40–50 cm)
Key Allergy Trait: Distinctive corded coat that sheds minimally; curls form natural cords that trap loose hair and dander.
Spain's versatile herding and water dog has a coat unlike any other on this list — it naturally forms into cords (similar to a Puli, but in a medium-sized dog). The cords trap shed hair and dander internally, meaning very little allergen escapes into the environment. However, coat maintenance is specialized: cords must be separated by hand regularly, and the coat is typically shaved once or twice per year. They're energetic, intelligent, and best suited to active owners. Lifespan: 12–15 years.
Why it made the list: The corded coat is a unique allergen-management system, though it requires owners willing to learn specialized grooming techniques.

Honorable Mentions & Breeds That Don't Qualify
Honorable Mentions
Miniature Poodle (10–15 lb): While technically below our medium-size threshold, many Miniature Poodles push toward 15–18 lb and may suit owners looking for a smaller medium dog. Their hypoallergenic credentials are unmatched.
American Hairless Terrier (12–16 lb): No coat means virtually no dander dispersal, but they fall below our weight range. Worth considering if size flexibility exists.
Coton de Tulear (9–15 lb): Cottony, low-shedding coat and exceptional temperament, but too small for the medium category.
Breeds Often Mislabeled as Hypoallergenic (Avoid for Allergy Sufferers)
Labradoodle / Goldendoodle (medium-sized variants): These designer crosses are frequently marketed as hypoallergenic, but coat type is unpredictable. An F1 Labradoodle (first-generation cross) has a 50/50 chance of inheriting a shedding coat from the Labrador or Golden Retriever parent. Only multigenerational (multigen) or F1B backcrosses consistently produce low-shedding coats — and even then, individual variation is significant. If you're set on a Doodle, insist on meeting the specific dog and spending at least 30 minutes in close contact before purchasing.
Maltese (4–7 lb): Hypoallergenic coat, but far below the medium-size range. Also prone to tear staining and dental issues that require extra care.
Shih Tzu (9–16 lb): Low-shedding but too small for this category, and their brachycephalic (flat-faced) structure creates respiratory concerns that add veterinary costs.
Managing Allergens at Home: Beyond the Breed
Even the most hypoallergenic breed will produce some allergens. According to the AAAAI, environmental management is just as important as breed selection. Here are evidence-based strategies:
- HEPA air purifiers: Place units in rooms where your dog spends the most time. Models like the Coway AP-1512HH ($200–$250) or Levoit Core 300 ($100–$130) capture particles as small as 0.3 microns — well below the size of Can f 1 allergen particles (approximately 2.5 microns).
- Bathing schedule: Bathe your dog every 2–4 weeks using a gentle, veterinary-formulated shampoo. Studies show that weekly bathing can reduce airborne Can f 1 levels by up to 84%, though this effect diminishes within days.
- Bedroom exclusion: Keep your dog out of the bedroom, especially off bedding. This single change can significantly reduce nighttime allergy symptoms.
- Washable surfaces: Replace carpeting with hard flooring where possible. If carpet is unavoidable, vacuum with a HEPA-filter vacuum (e.g., Shark Navigator Lift-Away, $150–$200) at least twice weekly.
- Grooming protocol: Have a non-allergic household member handle brushing, ideally outdoors. Wipe your dog's coat with a damp microfiber cloth after outdoor play to remove pollen and environmental allergens that can compound reactions.
Frequently Asked Questions
Are medium sized hypoallergenic dogs truly allergy-free?
No. The term "hypoallergenic" means less likely to trigger an allergic reaction, not allergy-free. Dog allergies are caused by proteins (primarily Can f 1 and Can f 2) found in saliva, dander, and urine. Even hairless breeds produce these proteins. The breeds on this list produce or disperse fewer allergens, but individual reactions vary. Always spend extended time with a specific dog before committing to ownership.
Why is the Soft Coated Wheaten Terrier ranked #1 over the Poodle?
While the Poodle's coat is technically the lowest-shedding, the Wheaten earns the top spot for the combination of its allergy-friendly coat, moderate exercise needs, exceptional family temperament, and slightly lower grooming costs. Poodles also require more frequent professional grooming (every 4–6 weeks vs. every 6–8 weeks for Wheatens), which adds up over the dog's lifetime. For allergy sufferers prioritizing a balanced family dog over competitive obedience or agility, the Wheaten often provides a better overall fit.
Can I test my allergy to a specific breed before buying?
Yes, and you should. Ask the breeder if you can spend 30–60 minutes with the specific puppy or adult dog in an enclosed space. Some allergists offer component-resolved diagnostics (CRD) that test your reaction to specific Can f proteins, which can help predict tolerance. You can also ask breeders to send you a sample of the dog's hair and dander (collected from brushing) to test at home by placing it near your sleeping area for a few nights.
How much do medium sized hypoallergenic dogs cost?
Purchase prices from responsible breeders typically range from $1,500 to $4,500 depending on breed rarity and location. The Standard Schnauzer tends to be the most affordable ($1,500–$2,500), while the Lagotto Romagnolo and Barbet command higher prices ($2,500–$4,500) due to limited U.S. availability. Annual care costs (food, grooming, veterinary, insurance) typically run $2,000–$3,500 per year. Factor in grooming specifically: budget $400–$900 annually for professional grooming, which is non-negotiable for these coat types.
Do mixed-breed dogs count as hypoallergenic?
Only if you can verify the coat type. Mixed breeds with Poodle, Bichon, or other low-shedding ancestry may inherit the allergy-friendly coat, but there's no guarantee. "Doodle" mixes (Labradoodle, Goldendoodle, Sheepadoodle) are especially unpredictable in F1 generations. If you're adopting a mixed breed, assess the coat directly: hair-like texture, minimal shedding when brushed, and curls or waves are positive indicators. Regardless of breed, consult your allergist before bringing any dog into a household with known dog allergies.
What should I do if my allergies flare up after bringing a dog home?
First, consult your allergist — they may adjust your medication or recommend immunotherapy (allergy shots), which can build tolerance over 1–3 years. At home, increase HEPA filtration, bathe the dog more frequently, and enforce bedroom exclusion. In severe cases where symptoms are unmanageable despite intervention, rehoming through a breed-specific rescue may be necessary — responsible breeders typically include a take-back clause in their contracts for this scenario.

If you have severe allergies, consult both your allergist and a veterinarian before selecting a dog breed. Always purchase from responsible breeders who perform health testing (OFA, CHIC, or equivalent) or adopt from reputable breed-specific rescues.
