Is the Dogue de Bordeaux Hypoallergenic? Maximum Drool, Maximum Allergen

No. The Dogue de Bordeaux scores 2.0 out of 10 — tied for the lowest possible score in the 99-breed set. Its AKC 5/5 drool rating means maximum saliva-borne Can f 1 deposition on all surfaces continuously, and its 99-to-110-plus-pound giant body amplifies total dander output above what a moderate-shedding smaller dog would produce. The short coat provides no allergen protection. Even people with mild dog allergy are very likely to experience significant symptoms living with a Dogue, and those with moderate-to-severe sensitivity should understand that this is among the hardest companion dogs to tolerate.

Two factors simultaneously reach their minimum in the scoring model. First, the AKC 5/5 drool rating drives the saliva-spread score to its floor (1 out of 10) — Can f 1 is a salivary protein (Polovic et al., Allergy, 2013), and maximum drool means continuous maximum allergen deposition from this route. Second, the combination of a 4/5 shedding rate and a giant body (99-110+ lb) clamps the dander score at the minimum (1 out of 10) after the giant-body penalty is applied. These two floor scores, combined with the universal low allergen-production score, produce the 2.0 composite.

Yes. The AKC 5/5 rating is the absolute maximum, and research confirms that dog saliva is an important allergen source independent of skin and hair (Polovic et al., Allergy, 2013). The Dogue's jowly lips collect and fling saliva with activity, meals, drinking, and excitement. When a jowly dog shakes its head, fine saliva aerosol is released directly into the air at face level — a particularly efficient inhalation exposure route. Every drool deposit on hard floors, furniture, and clothing is a concentrated Can f 1 source that persists until physically cleaned. For an allergic person, contact with drool-contaminated surfaces can trigger acute symptoms within minutes.

The Dogue de Bordeaux scores 2.0 out of 10, tied with the St. Bernard for the lowest score in the 99-breed set. The score blends five factors: allergen production at 40 percent (low for all dogs), shedding at 20 percent (poor — AKC 4/5), dander at 15 percent (minimum — giant-body penalty applied to high shedding), saliva spread at 15 percent (minimum — AKC 5/5 drool), and groomability at 10 percent (above average — short coat responds to bathing). The two minimum scores on dander and saliva, combined with the universal production floor, produce the 2.0 composite.

It can for a specific subset of allergic people. Intact males produce Can f 5, a prostatic kallikrein not present in females or neutered males (Mattsson et al., JACI, 2009). About 35 percent of dog-sensitized patients have IgE to Can f 5, and some react to it as a primary sensitizer. For those individuals, a neutered male or female Dogue de Bordeaux produces less of one allergen. However, given this breed's overwhelming saliva-based Can f 1 burden from maximum drool, reducing Can f 5 is a secondary benefit at best. Component-resolved blood testing confirms which proteins are driving symptoms.

They are identical in composite score at 2.0 — tied at the floor of the 99-breed set. Both are AKC 5/5 droolers with giant bodies reaching the same worst-case score via slightly different routes. The Dogue has a short single coat and higher shedding (4/5), while the St. Bernard has a double coat and moderate shedding (3/5). In practice, the allergen burden for an owner is essentially indistinguishable, and both represent the same honest challenge to an allergy sufferer.

You can reduce them, but probably not to a comfortable level for a moderately-to-severely allergic person without medical treatment. The approach must address both routes simultaneously. For drool: wipe the muzzle after every meal, drink, and play session; keep washable mats at resting spots; mop hard floors daily in dog-use areas; launder drool-contacted fabrics weekly. For airborne dander: multiple HEPA purifiers running continuously in every main room, bathing the dog every 1 to 2 weeks, hard flooring throughout, and an absolute dog-free bedroom. Daily antihistamines and nasal corticosteroids should be part of the baseline management alongside environmental controls.

Can f 1 is a stable lipocalin protein that persists in household dust for months, sometimes more than a year in heavily contaminated rooms. For a maximum-drool giant breed, the allergen enters through two particularly persistent routes: fine airborne dander particles settling into every surface, and concentrated saliva deposits drying on hard floors, furniture, and walls at muzzle height. The dried saliva residue is especially persistent and becomes airborne when disturbed by foot traffic or cleaning. Decontaminating a home that has housed a Dogue for years requires deep cleaning of carpet (if any), ductwork, upholstery, and drool-affected wall surfaces.

Potentially, but with honest expectations. Smith and Coop (Ann Allergy Asthma Immunol, 2016) found no clearly reproducible clinical evidence of effectiveness across 40 years of dog AIT studies — a weaker evidence base than for cat allergy, which has well-documented controlled-trial support. Immunotherapy remains the only disease-modifying option for allergy, retraining the immune system over a three-to-five-year course rather than just suppressing symptoms. Given the Dogue's extreme allergen burden, immunotherapy is an important complement to environmental management and medication — but realistic expectations about outcomes are essential.
