Is the Neapolitan Mastiff Hypoallergenic? Heavy Drool, Heavy Dander, Heavy Burden
No. The Neapolitan Mastiff is not hypoallergenic. It scores 2.0 out of 10 on the Hypoallergenic Score because its heavy drool (AKC 5/5) and moderate shedding (AKC 3/5) combine with a massive 150-pound frame to produce a very high total allergen load. The loose, wrinkled skin traps moisture and dander, and the breed's constant drool deposits saliva-borne Can f 1 on every surface it contacts.

Dog breedKey facts
The AKC rates the Neapolitan Mastiff a 3 out of 5 shedder, a 5 out of 5 drooler, and a 2 out of 5 for grooming ease.
The major dog allergen Can f 1 is produced in every dog's salivary and sebaceous glands regardless of coat type or breed.
The ACAAI states that studies have not shown any dog can be hypoallergenic.
Hypoallergenic-marketed dog breeds carried more Can f 1 in their hair (2.26 vs 0.77 µg/g) than ordinary breeds in direct measurement studies.
Can f 1 was detectable in 94.2% of 173 single-dog homes regardless of breed or shedding classification.
The Neapolitan Mastiff is one of the most challenging breeds for an allergic owner. The heavy drool deposits Can f 1 directly on every surface, and the massive frame produces substantial dander. Even with aggressive environmental controls, most allergic individuals will struggle. This is a breed where the honest medical advice is often to choose a different dog.
How we got to this score
The Curex Hypoallergenic Score isn't a gut call. It's a weighted sum of five measurable factors — here's exactly how this breed scored on each.
A massive Italian guardian breed whose heavy drool (AKC 5/5) and moderate shedding (AKC 3/5) combine with a 150-pound frame to produce a uniquely high allergen load. The loose, wrinkled skin traps moisture and dander, and the constant drool deposits saliva-borne Can f 1 on every surface the dog contacts.
No dog breed is 100% hypoallergenic — every dog produces Can f 1; breeds differ only in how much allergen they shed into your home and how easily you can keep it out of your air.

How the Curex Hypoallergenic Score works
The Curex Hypoallergenic Score rates a breed from 1 to 10, where 10 means the lowest realistic allergen burden for an allergic household. It is a transparent editorial rubric built from documented published sources — not a lab measurement of any specific Mastiff. Each score derives from AKC breed-trait ratings (shedding, drooling, and grooming on a 1-to-5 scale) combined with established allergen-biology evidence on Can f 1 and Can f 5. Five factors are weighted. Allergen production carries 40 percent because how much Can f 1 a dog makes is the biggest symptom driver and the factor owners can least control — every dog produces it in skin, saliva, and sebum regardless of breed. Shedding is 20 percent because loose, allergen-coated hair and dander are the primary delivery vehicles. Dander adds 15 percent: a massive dog at 150 pounds disperses far more total dander than a small dog at the same proportional shed rate. Saliva spread is 15 percent and carries special weight for this breed — the AKC 5/5 drool rating means constant, heavy saliva deposition. Groomability carries the final 10 percent. Each factor is scored 1 to 10 and multiplied by its weight; the weighted sum is rounded to the nearest half point. The score reflects exposure potential, not personal sensitivity — two people can live with the same Mastiff and react very differently.
| Factor | Weight | A 10/10 means |
|---|---|---|
| Allergen production | 40% | All dogs produce Can f 1 in saliva, dander, and sebum regardless of coat type (Vredegoor 2012; ACAAI). |
| Shedding | 20% | AKC rates the Neapolitan Mastiff 3 out of 5 — moderate shed from a short, dense coat; a 150-pound frame makes total dander output very high. |
| Dander | 15% | Massive body surface area combined with moderate shed rate produces high total dander; loose wrinkled skin traps and releases dander continuously. |
| Saliva spread | 15% | AKC drooling 5 out of 5 — constant, heavy drool deposits saliva-borne Can f 1 on floors, furniture, walls, and people throughout the day. |
| Groomability | 10% | AKC grooming 2 out of 5; the short coat is easy to brush but the massive size and wrinkled skin make thorough bathing and drying physically demanding. |
Each factor is scored 1–10 (10 = lowest allergen burden), then weighted and summed to a single 1–10 score. Every breed is scored on the same model, so the rankings form one consistent dataset.
Heavy drool, heavy dander: the Mastiff's dual allergen burden
The protein driving most dog allergies is Can f 1, a small lipocalin produced in salivary and sebaceous skin glands — not in the hair itself. The ACAAI states that studies have not shown any dog can be hypoallergenic. Around 50 to 75 percent of dog-allergic patients show IgE reactivity to Can f 1 (Thermo Fisher Phadia), making it the standard marker for household dog exposure. The Neapolitan Mastiff is a giant breed at 110 to 150 pounds with a short, dense coat and loose, wrinkled skin. The coat is not the primary problem — the drool is. The AKC rates the Neapolitan Mastiff a 5 out of 5 drooler, meaning constant, heavy saliva production. Since Can f 1 is abundant in saliva, the Mastiff deposits allergen directly onto floors, furniture, walls, and people throughout the day. The loose facial skin and jowls act as a reservoir, trapping moisture and dander that release continuously. At 150 pounds, the Mastiff has the largest body surface area of any breed in this bundle. Even at a moderate shed rate (AKC 3/5), that massive surface area produces substantial total dander. The short, dense coat allows dander to flake off freely into the air rather than being trapped in an undercoat. The combination of heavy drool, large body, and moderate shed creates a uniquely high and persistent allergen load. Vredegoor et al. (JACI 2012) found that hypoallergenic-marketed breeds carried higher Can f 1 in their hair (2.26 vs 0.77 µg/g). Nicholas et al. (Am J Rhinol Allergy 2011) found detectable Can f 1 in 94.2 percent of 173 single-dog homes with no breed-based difference. The Mastiff's allergen profile is distinct from the Dogue de Bordeaux in this bundle — both are heavy droolers, but the Mastiff's larger frame and higher shed rate make it the more challenging of the two.
“Short-haired or non-shedding breeds are safe because there’s less hair.”
The allergen is a microscopic protein in dander, saliva and skin oils. Hair is just the carrier.
Where the allergen comes from
Overall load for this breed: High
- DanderHigh
Moderate shed (3/5) from a massive 150-pound frame; loose wrinkled skin traps and releases dander continuously.
- SalivaHigh
AKC drooling 5/5 — constant, heavy drool is the primary allergen vector, depositing Can f 1 on every surface the dog contacts.
- Skin/sebumHigh
Sebaceous oils carry Can f 1; the loose skin folds trap moisture and dander, creating a persistent reservoir.
- UrineLow
Minor route; intact males also produce Can f 5, a prostatic kallikrein, that falls sharply after neutering.
What the Mastiff's heavy drool and massive frame mean for allergen exposure
Hypoallergenic potential is about how much allergen-laden material a dog spreads and how easily you can interrupt that spread. Higher scores mean friendlier for allergies. The Neapolitan Mastiff is among the most challenging breeds for allergy sufferers because it combines the two worst allergen vectors — heavy drool and substantial dander — on the largest possible frame. The short coat is easy to brush, but that is the only favorable trait.
Shedding
ModerateAKC 3/5 shedder; the moderate rate applied to a 150-pound frame produces high total dander output.
Dander
HighMassive body surface area and loose wrinkled skin create a high and persistent dander reservoir.
Drooling
HighAKC 5/5 drooler — constant, heavy saliva production deposits Can f 1 on every surface the dog contacts.
Grooming needs
ModerateAKC grooming 2/5; the short coat is easy to brush but the massive size and wrinkled skin make thorough bathing physically demanding.
Coat type
ModerateShort dense single coat; dander flakes freely into the air rather than being trapped in an undercoat.
A higher allergy-friendliness score means the trait contributes less allergen to your home. Levels reflect each trait’s relative contribution to exposure — not grooming convenience.
Confirm it’s really a pet allergy.
Symptoms blamed on a pet are often pollen, dust mites, or mold. A simple at-home test from Curex measures your specific IgE to dog and cat allergens — so you treat the right trigger instead of guessing.
Take the allergy quizWhat it really costs an allergic owner
The Neapolitan Mastiff is among the most expensive breeds for an allergic owner. The heavy drool (AKC 5/5) requires constant surface management — drool cleanup supplies, washable furniture covers, and frequent floor mopping. The massive 150-pound frame means larger HEPA units, more shampoo for bathing, and higher cleaning product costs. The short coat eliminates professional grooming bills, but the size and wrinkled skin make home bathing a physically demanding task that may require professional help. The overall added cost for an allergic Mastiff owner is among the highest in this bundle, exceeded only by breeds with both heavy drool and heavy shedding. The most cost-effective first step is confirming the allergen trigger before spending on renovations.
HEPA air purifier(s)
$300-$600 upfront, $80-$150/yr filtersMultiple large-room HEPA units are needed — the massive frame and moderate shed produce substantial airborne dander that requires continuous filtration.
Drool surface management supplies
$40-$80/monthConstant heavy drool requires washable furniture covers, daily floor mopping, and drool towels at every door. The 5/5 drool rating makes this the largest recurring cost.
Dog bathing and allergen-removal supplies
$40-$100/month (supplies or professional)Bathing a 150-pound Mastiff every one to two weeks is physically demanding and may require professional grooming. Dog washing cuts airborne Can f 1 by roughly 61 percent for several days (Hodson et al., JACI 1999).
Allergy-friendly flooring
$2,000-$7,000 one-timeHard flooring throughout is essential — carpet under a heavy drooler and moderate shedder becomes a permanent allergen reservoir that cannot be adequately cleaned.
HVAC and vacuum upgrades
$200-$600 + $80-$150/yrHigh-MERV HVAC filters and a sealed HEPA vacuum; change filters monthly. The heavy drool adds a moisture component that may require more frequent HVAC maintenance.
Antihistamines and nasal sprays
$80-$300/yrDaily OTC antihistamines and a steroid nasal spray for baseline symptom control; likely needed at higher doses than for lower-allergen breeds.
Allergist evaluation and treatment
Varies; often partly insuredComponent-resolved IgE testing and possible immunotherapy address the underlying sensitization; the disease-modifying option when environmental controls fall short.
Ranges are rough estimates for budgeting only and vary by region, home size, and how reactive you are.
Who the Neapolitan Mastiff realistically suits
The Neapolitan Mastiff is a massive, dignified, and protective guardian breed bred for property defense in Italy. It is a low-energy indoor dog that spends most of its day lying on floors and furniture, distributing Can f 1 from dander and heavy drool throughout the home continuously. Suitability for an allergic owner is extremely limited — this is one of the most challenging breeds for allergy sufferers. The heavy drool creates a unique management burden that goes beyond dander control. Saliva-borne Can f 1 is deposited on floors, walls, furniture, and people throughout the day. The breed's massive size means it cannot be easily confined to one area of the home. For most allergic individuals, the Neapolitan Mastiff is not a realistic choice without intensive medical intervention.
Mild allergy
Even people with mild, well-controlled dog allergy will find the Neapolitan Mastiff challenging. The constant heavy drool deposits Can f 1 on every surface, and the massive frame produces substantial dander. A strict management plan would require HEPA purifiers in every room, hard flooring throughout, daily drool surface cleaning, and regular bathing of the dog — a physically demanding task at 150 pounds. Most mildly allergic owners will still experience symptoms.
Moderate to severe allergy
Not workable without immunotherapy and likely not workable even then. The sustained allergen load from heavy drool and substantial dander on a massive frame creates an environment that is extremely difficult to manage with environmental controls alone. Most allergists would advise against this breed for anyone with moderate-to-severe dog allergy or allergic asthma.
Kids & asthma
Extra caution — the Neapolitan Mastiff is generally not recommended for households with asthmatic or eczema-prone children. The constant heavy drool and high dander load create a persistently high-allergen indoor environment. Early-life pet exposure has mixed evidence and is not a reliable route to building immunity in already-allergic children. A pediatric allergist assessment should precede any adoption decision.
Can you build tolerance? (immunotherapy for pet allergy)
Environmental controls reduce Can f 1 in your home but do not change how your immune system responds to it. Allergen immunotherapy is the one treatment that can. By delivering gradually increasing, controlled doses of dog allergen through subcutaneous shots (SCIT) or sublingual drops (SLIT), immunotherapy retrains the immune response away from the IgE-mediated pathway toward tolerance. It is the only treatment regarded as disease-modifying: benefits can persist after the course ends, unlike antihistamines and nasal sprays that only work while you take them. For dog allergy specifically, honest expectation-setting is essential. Cat-allergy immunotherapy has solid randomized controlled trial evidence — Varney et al. (Clin Exp Allergy 1997) found symptoms dropped from 61.6 to 17.1 in actively treated patients, and Alvarez-Cuesta et al. (Allergy 2007) reported a 62 percent reduction with sublingual therapy. Dog-allergy immunotherapy is much weaker. A 2016 review in Annals of Allergy, Asthma & Immunology by Smith and Coop concluded that studies over 40 years "failed to demonstrate any clearly reproducible clinical evidence" of effectiveness. Dog extracts are less standardized, and dogs have multiple relevant allergens including the male-dog-specific Can f 5. A typical AIT course runs three to five years, with gradual improvement over months. It is not a cure or a guarantee. For people with confirmed dog allergy not controlled by avoidance and medication, immunotherapy is the most rational next step under allergist supervision.
If you are allergic and want to keep your Mastiff, Curex connects you with allergist-supervised immunotherapy for pet allergy aimed at reducing your sensitivity over a multi-year course. Keep expectations realistic: dog immunotherapy is far less proven than cat immunotherapy and offers no guarantee of relief. Take the quiz to find out whether you are a candidate.
Immunotherapy may provide long-term relief but is not a guaranteed cure; outcomes vary and treatment is prescribed after a board-certified allergist review.
How to live with a Neapolitan Mastiff if you are allergic
If you share your home with a Neapolitan Mastiff and experience allergy symptoms, the first step is to confirm the trigger. Many people assume their symptoms are from dust or pollen because the dog's short coat looks low-maintenance. Do not assume — confirm it with Curex at-home allergy testing, which measures your IgE to Can f 1, the major dog allergen, so you treat the actual trigger. The quiz is a good starting point. Once the Mastiff is confirmed as your trigger, the management plan must address both the heavy drool and the substantial dander. The drool is the primary vector — saliva-borne Can f 1 is deposited on every surface the dog contacts. The dander is secondary but substantial given the massive frame. Unlike breeds with seasonal shedding, the Mastiff's allergen load is constant year-round, requiring consistent daily management.
- 01
Confirm the allergen trigger
Test for Can f 1 and Can f 5 specifically. Can f 5 from an intact male Mastiff may be part of your sensitization — component-resolved testing clarifies whether sex selection could reduce exposure without other changes.
- 02
Enforce a strict pet-free bedroom
Keep the Mastiff out of the bedroom and off the bed; wash bedding weekly in hot water above 130°F. The heavy drool and dander from a 150-pound dog contaminate every surface — protecting the bedroom gives you eight hours of lower-allergen air per night.
- 03
Manage drool surfaces continuously
Wipe down floors, walls, and furniture the Mastiff contacts multiple times daily. Keep drool towels at every door. Use washable furniture covers. The 5/5 drool rating means saliva-borne Can f 1 is deposited constantly — surface management is the most critical daily task.
- 04
Run HEPA air purifiers continuously
Place correctly sized HEPA units in every room the dog occupies. The short dense coat allows dander to flake freely into the air, and the massive frame produces substantial airborne particles. Continuous filtration is essential.
- 05
Bathe the dog every one to two weeks
Regular bathing reduces surface Can f 1 significantly; airborne levels fall roughly 61 percent for several days following a wash (Hodson et al., JACI 1999). A 150-pound Mastiff may require professional grooming for bathing — factor this into the cost and schedule.
- 06
Replace carpet with hard flooring
Carpet under a heavy drooler and moderate shedder becomes a permanent allergen reservoir. Hard floors can be damp-mopped to remove both settled dander and dried drool residue. This is the most impactful one-time structural investment for allergen control.
How it stacks up against other breeds
Scored on the same five-factor model, the Neapolitan Mastiff lands at 2.0 — in the Not hypoallergenic band — because its heavy drool (AKC 5/5) and moderate shedding (AKC 3/5) combine with a massive 150-pound frame to produce a uniquely high allergen load. The Dogue de Bordeaux, a similar heavy-drooling breed, reaches 2.5 by having a slightly smaller frame and lower shed rate. The Bloodhound, another heavy drooler, also scores 2.0 with a similar profile. No dog reaches a true 10 on this model.

Frequently asked questions
Are Neapolitan Mastiffs good for allergy sufferers?
No. Neapolitan Mastiffs score 2.0 out of 10 on the Hypoallergenic Score, placing them in the Not hypoallergenic band and among the most challenging breeds for allergy sufferers. The heavy drool (AKC 5/5) deposits saliva-borne Can f 1 on every surface, and the massive 150-pound frame produces substantial dander even at a moderate shed rate (AKC 3/5). The ACAAI states that studies have not shown any dog can be hypoallergenic. Most allergic individuals will find this breed unmanageable without intensive medical intervention.
Do Neapolitan Mastiffs shed a lot?
Moderately, year-round. The AKC rates the Neapolitan Mastiff a 3 out of 5 shedder — middle of the scale. The short, dense coat sheds steadily without dramatic seasonal blows. For allergy purposes, the moderate shed rate applied to a 150-pound frame produces high total dander output. The loose, wrinkled skin traps dander and releases it continuously, making the allergen load higher than the shed rating alone suggests.
Why is the Neapolitan Mastiff so bad for allergies despite having a short coat?
Because the short coat is not the problem — the heavy drool is. The AKC rates the Neapolitan Mastiff a 5 out of 5 drooler, meaning constant, heavy saliva production. Since Can f 1 — the major dog allergen — is abundant in saliva, the Mastiff deposits allergen directly on floors, furniture, walls, and people throughout the day. The massive 150-pound frame also produces substantial dander even at a moderate shed rate. The short coat reduces grooming bills; it does not reduce allergen output.
What hypoallergenic score does the Neapolitan Mastiff get?
The Neapolitan Mastiff scores 2.0 out of 10, placing it in the Not hypoallergenic band. The five-factor breakdown: allergen production 2/10 (40% weight; near-constant for all dogs), shedding 2/10 (20% weight; AKC 3/5 on a massive frame), dander 2/10 (15% weight; large body and loose skin), saliva spread 1/10 (15% weight; AKC 5/5 heavy drool), and groomability 3/10 (10% weight; easy short coat but physically demanding to bathe). The 1/10 saliva spread score is the lowest possible and reflects the constant heavy drool.
Does neutering a male Neapolitan Mastiff reduce dog allergies?
For a minority of dog-allergic people, yes. Intact male dogs produce Can f 5, a prostatic kallikrein, in addition to Can f 1. Around 30 percent of dog-allergic patients are sensitized to Can f 5, and some react to it exclusively. Neutering eliminates the Can f 5 source, which can meaningfully reduce symptoms for monosensitized patients. For the majority sensitized to Can f 1 — present in every dog regardless of sex or neuter status — neutering makes no practical difference. Given the Mastiff's heavy drool, Can f 1 dominates the allergen profile regardless.
How does the Neapolitan Mastiff compare to the Dogue de Bordeaux for allergies?
Both are heavy-drooling giant breeds with similar profiles, but the Dogue de Bordeaux is slightly less challenging. The Dogue de Bordeaux scores 2.5 versus the Mastiff's 2.0 because it has a smaller frame (100 to 110 pounds versus 150 pounds) and a lower shed rate (AKC 2/5 versus 3/5). Both have the same AKC 5/5 drool rating. In practice, the Mastiff's larger body and higher shed rate produce more total dander, making it the more difficult of the two for allergy sufferers.
Is the Neapolitan Mastiff better for allergies than the Labrador Retriever?
No — they are comparably challenging for different reasons. The Labrador Retriever scores 2.0 with a dense double coat and heavy shed (AKC 4/5) but low drool (AKC 1/5). The Neapolitan Mastiff also scores 2.0 with moderate shed (3/5) but heavy drool (5/5). The Lab's allergen burden comes from airborne dander; the Mastiff's comes from both airborne dander and surface-deposited saliva. For most allergic individuals, the Mastiff's heavy drool makes it the more difficult of the two to manage.
Can I reduce allergens from a Neapolitan Mastiff at home?
Partially, but it is extremely challenging. The most effective measures are: keep the dog out of the bedroom, run HEPA air purifiers in every room, replace carpet with hard flooring that can be damp-mopped, and bathe the dog every one to two weeks. The heavy drool requires constant surface management — wipe down floors, walls, and furniture multiple times daily. Dog washing cuts airborne Can f 1 by roughly 61 percent for several days (Hodson et al., JACI 1999), but bathing a 150-pound Mastiff is physically demanding. Even with all measures, most allergic individuals will still experience symptoms.
How does the Neapolitan Mastiff allergen profile differ from the Bloodhound?
Both are heavy droolers (AKC 5/5) with large frames and moderate shed rates, scoring 2.0 on the Hypoallergenic Score. The differentiators are frame size and coat type. The Bloodhound is slightly smaller at 80 to 110 pounds with a short, dense coat. The Neapolitan Mastiff is larger at 110 to 150 pounds with a short, dense coat and loose, wrinkled skin that traps dander. The Mastiff's wrinkled skin creates a persistent dander reservoir that the Bloodhound's smoother skin does not. Both are among the most challenging breeds for allergy sufferers.
Can immunotherapy help me keep a Neapolitan Mastiff if I am allergic?
For some people, yes — with honest expectations for dog allergy. Allergen immunotherapy gradually retrains the immune system over a three-to-five-year course and is the only disease-modifying treatment. Cat-allergy immunotherapy has solid randomized trial support; dog-allergy immunotherapy is considerably weaker — a 2016 review in Annals of Allergy, Asthma & Immunology concluded that four decades of studies failed to produce clearly reproducible clinical evidence of effectiveness. Dog extracts are less standardized and the multi-allergen complexity of dog sensitization complicates treatment. Even with immunotherapy, the Mastiff's heavy drool and high dander load may still trigger symptoms. Immunotherapy is not a cure, but for people with confirmed dog allergy not controlled by avoidance and medication, it is the rational next step under allergist supervision.
