How big does a Grand Basset Griffon Vendeen get when fully grown?

Published October 30, 2026

The short answer

A fully grown Grand Basset Griffon Vendeen stands about 15.5 to 18 inches at the shoulder and weighs roughly 40 to 45 pounds, because despite the basset name it is a long-legged, full-sized scent hound rather than a dwarf breed. Males and females are closer in size than in many breeds, and the rough coat and long body make the dog look rangier than the scale reports. Plan for a medium-large hound's strength on the leash, not a small dog's. A KinsLe Pet Pass keeps your GBGV's verified identity, weight, and your contact details on one card, handy for hunt clubs, boarding, and vet visits alike.

Not a dwarf: GBGV size explained

A fully grown Grand Basset Griffon Vendeen stands 15.5 to 18 inches at the shoulder and weighs about 40 to 45 pounds. The word basset misleads people, because in this breed it refers to a lower-slung style of hound, not to the short-legged dwarfism of the Basset Hound; the GBGV is a long-legged, rough-coated French scent hound built to hunt all day over rough ground in the Vendee. Males and females differ less than in most breeds, with males only slightly taller and heavier.

Long, low-ish, and stronger than expected

A Grand Basset Griffon Vendeen's body is longer than its height, carried on straight, well-boned legs, with a deep chest and a famously harsh double coat. That construction produces a dog who pulls on leash like a much heavier animal and can hold his ground physically in a way that surprises owners expecting a dog barely knee-high. The shaggy outline hides the muscling, so, as with other coated breeds, condition is judged by hand and scale rather than silhouette. Forty-five pounds of determined scent hound is a medium-large dog in every practical sense.

When a GBGV reaches full size

Grand Basset Griffon Vendeens grow steadily, reaching near-adult height by about ten to twelve months and filling out through the chest and shoulders by 18 months to two years. Hound adolescents are notoriously ribby-looking at certain stages, and the breed's metabolism and exercise levels make lean normal rather than concerning in a young dog. Overfeeding to smooth out the adolescent outline produces a genuinely overweight adult on a long back, which is exactly the combination to avoid. Track weight monthly through the second year so the fill-out is muscle, not fat sneaking under the coat.

Daily life with a 40-pound scent hound

The GBGV's size fits standard medium-large crates and cars, but the breed's real spatial demand is a securely fenced yard, because a hunting hound of this build can dig, climb, and commit to a scent trail with athletic seriousness. Indoors, adults are companionable and less boisterous than their hunting energy suggests, provided the exercise and nose work are genuinely delivered. The beard and rough coat import a remarkable quantity of water and debris, so the dog's footprint in a house is bigger than 45 pounds implies. Voice is also part of the package, since a pack hound's bay carries, which matters more in dense housing than the dog's dimensions do.

Choosing a GBGV and judging adult size

The breed's narrow weight range makes adult size predictable, and breeders should quote both parents' weights readily. Distinguish carefully from the Petit Basset Griffon Vendeen, the smaller cousin at roughly half the weight, because the two breeds are confused constantly in listings and occasionally in rescue paperwork. If you are adopting, confirm which breed, or which mix, you are actually looking at before planning equipment around a number. A mismatched assumption here is the difference between planning for 20 pounds and living with 45.

One card with the dog's true details

A breed this often mistaken for its smaller cousin benefits from documentation that states plainly what the dog is and what he weighs. A KinsLe Pet Pass records your Grand Basset Griffon Vendeen's verified identity, measured weight, and your contact details in one place, so kennels, hunt organizers, and clinics deal with the actual dog on file rather than a guess based on a confusing name.
