Grand Bleu de Gascogne
A large, noble French scenthound with a distinctive blue-mottled coat and deep voice. Gentle and sociable, but a slow, dedicated tracker needing space and exercise.
Grand Bleu de Gascogne scorecard
Overview
The Grand Bleu de Gascogne is a large, noble French scenthound from the Gascony region of south-western France, instantly recognisable by its distinctive blue-mottled coat — a black-and-white ticked pattern that gives a blue-grey impression — and its long, drooping ears. Standing roughly 62–72 cm and weighing around 32–35 kg, it is one of the oldest and most influential of the French scenthounds, a dignified dog built for stamina and a slow, methodical hunt.
The breed is recognised by the Fédération Cynologique Internationale (FCI) and has contributed to the bloodlines of many other hounds, including American coonhounds. It is rare in the UK and is not a Kennel Club breed here. Gentle, sociable and deep-voiced, the Grand Bleu is a classic pack hound whose needs and character are firmly those of a working scenthound.
Good to know — a Grand Bleu de Gascogne needs plenty of space and better with some experience. Every dog is an individual, so meet a few and chat to a good breeder or rescue before deciding.

History & origins
The Grand Bleu de Gascogne is an ancient breed, with roots tracing back centuries in the Gascony region, where it was developed to hunt large game and later hare and other quarry by scent. It is regarded as one of the foundational French scenthounds and has influenced numerous related breeds across Europe and North America.
Traditionally hunted in packs, the Grand Bleu was prized not for speed but for its exceptional nose, persistence and deep, sonorous voice, which allowed hunters to follow the progress of a chase by ear. That heritage as a slow, determined and vocal tracker remains central to the breed's identity today.
Temperament & family fit
The Grand Bleu de Gascogne is typically gentle, calm and sociable, with the amiable, cooperative temperament of a pack hound. It is usually good-natured with people and very sociable with other dogs, reflecting generations of communal hunting, and it tends to be affectionate and tolerant within its family.
Alongside that gentle nature, however, sits a powerful scent drive and a deep, far-carrying bay. These are independent, nose-led dogs that can become single-minded on a trail, and their voice is a defining feature of the breed. They are happiest with company and a sense of purpose rather than long hours alone.
- Families with children of all ages
- Owners ready for consistent training
- Active homes with plenty of space
Training & intelligence
As a pack scenthound bred to work independently and follow a scent over long distances, the Grand Bleu is not naturally obedient in the way a companion breed is. Reward-based, patient and consistent training gives the best results, but recall in the presence of scent is a persistent challenge, and many owners rely on secure areas and long lines for off-lead exercise.
Early, thorough socialisation helps the breed settle into family life, and channelling its instincts into scent work or tracking is far more rewarding than expecting precise obedience from a dog bred to think for itself.
- Start socialisation & handling early
- Reward-based methods only — no harsh corrections
- Channel energy into training games & enrichment
Exercise needs
A healthy adult Grand Bleu de Gascogne typically needs 90 minutes to 2 hours a day (roughly 90–120 minutes), split across walks, play and a little training. Higher-energy dogs also need their brains tired — sniffy walks, training games and puzzle feeding go a long way. Puppies, seniors and dogs with health conditions need adjusted amounts — check with your vet.
Grooming & coat
Grooming needs are low. The short, dense coat requires only occasional brushing to remove loose hair and keep it in good condition. The main routine concern is the long, pendulous ears, which trap moisture and debris and should be checked and cleaned regularly to prevent infection, along with standard nail trimming and dental care.
- Brush occasionally to remove loose hair
- Bathe every few weeks or as needed
- Check ears, nails and teeth weekly
Feeding a Grand Bleu de Gascogne
Feed a complete, good-quality diet suited to the dog's large size, age and activity level, divided into two meals a day and adjusted to maintain a lean, well-muscled body. As a large, deep-chested hound, it is wise to keep the dog from becoming overweight and to avoid strenuous exercise immediately before and after meals.
A large breed
An adult Grand Bleu de Gascogne typically weighs 32–35 kg, so a healthy Grand Bleu de Gascogne eats a fair amount compared with other breeds. Every feeding guide on a bag is written per kilo of body weight, not per breed — start there, then adjust to the dog in front of you.
Life stage
A large breed is usually done growing at 15–18 months, which is roughly when a puppy food has finished its job. With a typical lifespan of 10–12 years, there is a long adult stretch in the middle; switch to a senior food when your vet thinks it is worth it rather than on a birthday.
A high-energy dog eats like one
Grand Bleu de Gascognes sit at the top end for energy, and a dog working through an hour and a half of real exercise a day burns through the feeding guide faster than a dog on a short stroll. Feed to the dog's condition, not to the middle of the range on the bag.
Joint support is worth looking for
Their size and frame put more load through the joints than a smaller dog carries, so a food with joint support on the label is worth reading for — and keeping them lean does more for their joints than any supplement.
Weight matters more than usual here
A long back or a heavy frame makes every extra kilo count twice. Weigh portions rather than eyeballing a scoop, and reduce the food rather than the walks if the waist starts to disappear.
How much should a Grand Bleu de Gascogne weigh?
Adult 32–35 kgfully grown at 15–18 months
| Age | Stage | Typical weight | Of adult size |
|---|---|---|---|
| 8 weeks | Just home | 3.7–4 kg | 11% |
| 3 months | Young puppy | 5.9–6.5 kg | 19% |
| 6 months | Growing fast | 11.9–13 kg | 37% |
| 12 months | Adolescent | 23.8–26 kg | 74% |
| 15–18 months | Fully grown | 32–35 kg | 100% |
A guide, from the same rule of thumb our puppy growth predictor uses — each age is that share of the way to maturity for a large breed. Puppies grow fastest early, so a real puppy usually sits a little above the middle rows. Weigh yours and ask your vet if the number worries you.

The Grand Bleu de Gascogne is generally regarded as a hardy, robust breed, but as an uncommon hound there is limited large-scale, breed-specific health and longevity data, and a typical lifespan of around 10–12 years should be treated as a general estimate. Where breeders maintain working lines, the emphasis has long been on soundness and function.
As a large, deep-chested, drop-eared hound, the breed shares the general health considerations of its type: bloat is a serious risk to understand, the long ears need regular care to prevent infection, and keeping the dog lean protects the joints. The conditions below reflect those typical of large scenthounds rather than disorders proven to be unusually frequent in this particular breed.
Common health conditions to be aware of
- Ear infections (otitis) — long, pendulous ears retain moisture and require regular checking and cleaning.
- Gastric dilatation-volvulus (bloat) — a life-threatening emergency in deep-chested dogs; recognise the signs and act quickly.
- Hip dysplasia — a developmental joint disorder common in large breeds; keep the dog lean to reduce strain.
- Eye conditions such as entropion — inward-rolling eyelids can occur in loose-skinned hounds and may need veterinary attention.
- Musculoskeletal injuries — an occupational risk for a hard-working tracking hound.
- Obesity — a danger if exercise is reduced, contributing to joint and metabolic problems.
These reflect typical, size- and coat-related risks for dogs like the Grand Bleu de Gascogne; individual breeds carry their own predispositions. Always buy from health-tested parents and speak to your vet — this isn't a diagnosis.

Bringing home a Grand Bleu de Gascogne puppy
Puppies need controlled exercise (a rough guide is five minutes per month of age, twice a day) to protect growing joints, little-and-often meals of a complete puppy food, early socialisation, and a calm routine for toilet training and sleep. Book first vaccinations, microchipping and a vet check early.
New puppy checklist →Caring for a senior Grand Bleu de Gascogne
As they age, watch weight, joints and teeth, switch to a senior diet if your vet advises, keep exercise gentle but regular, and consider orthopaedic bedding and ramps. Twice-yearly vet checks help catch issues early — larger breeds age sooner, so start senior care from around 6–7 years.

Frequently asked questions
How big does a Grand Bleu de Gascogne get?
This is a large, noble French scenthound. Adults typically stand around 62 to 72 cm at the shoulder and weigh roughly 32 to 35 kg. It is instantly recognisable by its distinctive blue-mottled coat, a black-and-white ticked pattern giving a blue-grey impression, and its long, drooping ears. The build is dignified and made for stamina over a slow, methodical hunt.
What is the lifespan of a Grand Bleu de Gascogne?
A typical lifespan of around 10 to 12 years is commonly cited, in line with similar large scenthounds. The breed is generally regarded as hardy and robust, but as an uncommon hound there is limited large-scale, breed-specific longevity data, so this should be treated as a general estimate. Keeping the dog lean helps protect its joints over time.
What is the temperament of the Grand Bleu de Gascogne?
It is typically gentle, calm and sociable, with the amiable, cooperative temperament of a pack hound. It is usually good-natured with people, very sociable with other dogs, and affectionate within its family. Alongside that gentle nature sits a powerful scent drive and a deep, far-carrying bay, and it can become single-minded once on a trail.
How much exercise does a Grand Bleu de Gascogne need?
This is an active, high-stamina hound needing substantial daily exercise, well over an hour of varied activity. It particularly benefits from the chance to follow scent and run in safe, enclosed areas. A bored or under-exercised Grand Bleu is prone to frustration and noise, so it suits active, outdoor-minded owners with access to plenty of space rather than a quiet urban home.
Is the Grand Bleu de Gascogne easy to train?
As a pack scenthound bred to work independently and follow a scent over long distances, it is not naturally obedient like a companion breed. Reward-based, patient and consistent training works best, but recall around scent is a persistent challenge, so many owners rely on secure areas and long lines. Early socialisation and channelling its instincts into scent work pay off most.
Is the Grand Bleu de Gascogne good with children and other dogs?
It is generally affectionate and tolerant within its family and very sociable with other dogs, reflecting generations of communal hunting. As with any large, energetic hound, interactions with young children should be supervised. Its deep, carrying bay and need for company mean it does best in an active household where it is not left alone for long.
Does the Grand Bleu de Gascogne need much grooming?
Grooming needs are low. The short, dense coat requires only occasional brushing to remove loose hair and keep it in good condition. The main routine concern is the long, pendulous ears, which trap moisture and debris and should be checked and cleaned regularly to prevent infection, along with standard nail trimming and dental care.
What health issues affect the Grand Bleu de Gascogne?
It is generally regarded as a hardy, robust breed, though detailed breed-specific data is limited. As a large, deep-chested, drop-eared hound, the main considerations are typical of its type: bloat is a serious risk to understand, the long ears need regular care to prevent infection, and keeping the dog lean protects the joints. Discuss preventive care with your vet.
Are Grand Bleu de Gascognes good with children?
Good with children. As a general guide, Grand Bleu de Gascognes tend to be patient and tolerant. Whatever the breed, always supervise dogs and young children and teach kids to interact gently.
How much exercise does a Grand Bleu de Gascogne need?
As a healthy adult, a typical Grand Bleu de Gascogne needs 90 minutes to 2 hours of exercise a day (90–120 minutes), split across walks plus play. Higher-energy dogs also need mental stimulation — sniffing, training games and puzzle feeders — to stay settled. Puppies, seniors and dogs with health conditions need less — ask your vet.
Do Grand Bleu de Gascognes shed a lot?
Moderate shedding. Coat upkeep is wash-and-go — a quick brush now and then is usually enough.
Are Grand Bleu de Gascognes easy to train and good for first-time owners?
Better with some experience. Grand Bleu de Gascognes are best for owners ready to commit to consistent training and plenty of activity. Reward-based training and early socialisation help any dog.
Do Grand Bleu de Gascognes bark a lot?
Vocal / alert barker. They can be quite vocal, so early training and enough exercise and stimulation help keep barking in check.
Are Grand Bleu de Gascognes good with other dogs?
Very sociable with other dogs. Early, positive socialisation with other dogs from a young age makes a big difference.
Do Grand Bleu de Gascognes suit flats or smaller homes?
Needs plenty of space. A Grand Bleu de Gascogne really needs plenty of space and a lot of daily activity — not ideal for a small flat.
