This page includes an interactive dog years calculator: https://dogyears.info/korthals-griffon-dog-years. ## How long do Korthals Griffons live? This site does not publish a breed-specific UK median lifespan for the Korthals Griffon. Individual dogs vary. The calculator converts the years a dog has already lived. It is not a forecast of how long they will live. A 2024 Dogs Trust study of UK dogs found that larger dogs tended to have shorter lives than smaller ones, and flat-faced breeds shorter lives than dogs with a typical head shape. That pattern is not a lifespan figure for this breed. [Signs your dog is a senior](https://dogyears.info/signs-your-dog-is-a-senior) covers what to watch for as a dog gets older. Source: [Dogs Trust, longevity of UK dog breeds (2024)](https://www.dogstrust.org.uk/about-us/research-expertise/longevity-dog-breeds), reporting McMillan et al., [Scientific Reports](https://doi.org/10.1038/s41598-023-50458-w). ## Korthals Griffon age in human years | Dog years | Human years | Life stage | | --- | --- | --- | | 1 | 15 | Adolescent | | 2 | 24 | Adult | | 3 | 28 | Adult | | 4 | 32 | Adult | | 5 | 36 | Senior begins | | 7 | 50 | Senior | | 8 | 55 | Senior | | 10 | 66 | Senior | | 12 | 77 | Geriatric | | 13 | 82 | Geriatric | Figures based on The Royal Kennel Club's published large-breed guidance, as tabulated by Purina UK. The same numbers power the widget above and the [main calculator with Korthals Griffon selected at 5 years](https://dogyears.info/?b=Korthals%20Griffon&a=5). Want an exact figure including months? Use a decimal age in the widget (for example 7.5) or open the full calculator. The Korthals Griffon is classified by The Royal Kennel Club as a large breed, typically weighing 23–27 kg as an adult. Developed in the 1870s by Dutch breeder Eduard Korthals, this shaggy, wire-coated gundog is a versatile all-rounder, equally happy pointing, retrieving, and tracking across varied terrain. This site does not publish a breed-specific UK median lifespan for the Korthals Griffon. Individual dogs vary, and a size-band chart is not a life-expectancy forecast. Use the large-breed numbers to convert the years you already have — not to predict the years still to come. A 7-year-old Korthals Griffon is about 50 in human years on the Royal Kennel Club large-breed table; a 7-year-old small breed is still in middle age on the small-breed table. See [small vs large breed ageing](https://dogyears.info/small-vs-large-breed-ageing) for why size changes the maths. ## Worked examples using this site's calculator These are the same Royal Kennel Club large-breed figures the homepage uses — not a separate formula. The classic ×7 rule is shown only as a comparison; it is the rule this site exists to replace. More on that in [Is the ×7 rule real?](https://dogyears.info/dog-years-x7-rule-explained) | Your Korthals Griffon | RKC human years | ×7 rule | What that stage usually means | | --- | --- | --- | --- | | 3 years | 28 | 21 | Adult — ×7 understates the early years | | 5 years | 36 | 35 | Senior begins on the large-breed table | | 7 years | 50 | 49 | Solidly senior; ×7 is briefly close | | 10 years | 66 | 70 | ×7 starts to overstate | Open the [full calculator at 5 years, Korthals Griffon already selected](https://dogyears.info/?b=Korthals%20Griffon&a=5), or pick another age on this page. Birth-date entry, named results, and the share card live on the homepage, not in this widget. ## What this means for your Korthals Griffon Hip dysplasia is worth screening for given the breed's active working build, though the Korthals Griffon is generally considered hardy given its versatile working heritage. Eyelid conditions such as entropion are also occasionally reported. The wiry, weatherproof coat needs periodic hand-stripping rather than regular clipping to maintain its texture throughout your dog's life. None of that is a diagnosis, and this page is not a substitute for your vet. The useful takeaway is practical: twice-yearly check-ups from around 5 dog years, a monthly look at body condition, and catching sudden changes early. That is the unglamorous version of healthy ageing. ## When is a Korthals Griffon considered a senior? Under The Royal Kennel Club's size-adjusted guidance, large breeds like the Korthals Griffon are generally considered senior from around **5 dog years** old. 5 dog years maps to about 36 human years on the large-breed table. By 7 (about 50), many owners notice a slower rise from the bed and a shorter stride on the second walk. Gradual change is common; sudden lameness, rapid weight loss, or a new lump is the point to read [when to take your senior dog to the vet](https://dogyears.info/when-to-take-senior-dog-to-vet) rather than wait for the next routine slot. Insurers do not have to use the same "senior from 5" line. A 5-year-old Korthals Griffon is already in the senior life stage on this site, but a given UK insurer may still treat that dog as mid-life for a new quote — or may already apply a higher excess. If you are weighing cover, read [pet insurance for older dogs](https://dogyears.info/pet-insurance-for-older-dogs) alongside this chart rather than assuming the two clocks match. ## How Korthals Griffons compare with other large UK favourites On this site Korthals Griffons share the large band with [German Wirehaired Pointer](https://dogyears.info/german-wirehaired-pointer-dog-years) and [Italian Spinone](https://dogyears.info/italian-spinone-dog-years), so the year-by-year human-years numbers are the same. We only repeat a Dogs Trust median where this site already publishes one. If you have two of those breeds at home, the [breed comparison tool](https://dogyears.info/compare?a=Korthals+Griffon&b=German+Wirehaired+Pointer) puts the ageing tables next to each other. It will not invent a different curve than the size-band maths already on each page. ## Common questions ### How long do Korthals Griffons live? This site does not publish a breed-specific UK median lifespan for the Korthals Griffon. Individual dogs vary. The calculator converts the years a dog has already lived. It is not a forecast of how long they will live. A 2024 Dogs Trust study of UK dogs found that larger dogs tended to have shorter lives than smaller ones, and flat-faced breeds shorter lives than dogs with a typical head shape. That pattern is not a lifespan figure for this breed. [Signs your dog is a senior](https://dogyears.info/signs-your-dog-is-a-senior) covers what to watch for as a dog gets older. Source: [Dogs Trust, longevity of UK dog breeds (2024)](https://www.dogstrust.org.uk/about-us/research-expertise/longevity-dog-breeds), reporting McMillan et al., [Scientific Reports](https://doi.org/10.1038/s41598-023-50458-w). ### How old is a 5-year-old Korthals Griffon in human years? About 36, using The Royal Kennel Club's large-breed guidance as tabulated by Purina UK. That is also the point this site treats as the start of the senior stage for Korthals Griffons. The ×7 rule would say 35 — close at some ages, then it drifts. ### Why does a Korthals Griffon count as senior earlier than a small dog? Large breeds reach old age faster than small ones on the Royal Kennel Club tables this site uses. Small breeds are generally treated as senior from around 10 dog years; Korthals Griffons from around 5. It is a size-band guideline for care and check-ups, not a switch that flips overnight. See [dog life stages explained](https://dogyears.info/dog-life-stages-explained). ### Can I pre-fill the main calculator with Korthals Griffon? Yes. The homepage applies a shared link when an age is present, so use [Korthals Griffon at 5 years](https://dogyears.info/?b=Korthals%20Griffon&a=5) or [7 years](https://dogyears.info/?b=Korthals%20Griffon&a=7), then change the age if you need a different figure. The widget on this page is the same large-breed maths in a shorter form. ### Get the exact figure, to the month Opens the homepage calculator with Korthals Griffon selected at 5 years — the start of the senior stage on the large-breed table.
