Obviously I know a lot depends on size etc but does anyone find certain breeds age in mobility terms such as arthiritis etc than others?

Bigger breeds tend to age quicker (ie a three year old dobe, acts a lot older than a 3 year old min pin - well at least most days!)

I find min pins grey out quicker than my spaniel did though!  To see grey hair on a 5 year old min pin is normal almost, but I didnt see grey hair on Joy until she was 11!!!  

yes, the giant breeds all tend to age a lot faster. that being said they also have a shorter old age

tio, my bullmastiff, has a grey 'soul-patch' and he's just hit 3. kizzy, our older girl is 6 and is really grizzled but she went grey at about 10 weeks, shes just a bit odd lol

my vet told me he thinks of gaint large breeds more as 1 human year to 10 dog years.
not as 1 human year to 7 dog years like most breeds.
As they do tend to have a shorter life span then other breeds.
Ave life span at the moment in Newfs is around 10 years so he's proberly on the mark with that thinking.

My black staffie cross started going grey around the muzzle at about the age of three, hes now nearly six and has also started to get grey eyebrows to go with his distinguished beard! ;-) :-P

My five year old pug started going grey at the age of two, she now looks much older than her years, bless her :-)

People are always really surprised when I tell them how old my Samoyed is (she's 9) as she does look really young - but Sammies dont seem to age like other breeds do. She had some mobility problems when we got her but they were down to her weight problems - she's fine now.

I think it is well known that Jack Russells are amongst the most long lived.  We had one ( a rescue) called Kit and he  lived to be 20 years old!

Blimey, not mine or any of the Dobes I have ever met - they are known for being immature clowns all their lives that never lose thier bounce!

I know quite a lot of greys that seem old before their time in looks and personality but often just because they are so laid back.  Also if they have raced this can really age them.  I often see labs that seem older than their age aswell but this is usually over weight and under-exercised dogs.  A lot of giant breeds age more quickly and have shorter life spans, A lot of Danes look quite old by the times they are four or five :-(

Our oldest dogue is almost 7 and he's definitely slowed down recently. He's in good health, a recent check up finds him so, but he acts older than his chronological age. It's just a large breed thing I think.

Our schipperkes are well known for their long lives and pubety ie from 10mths to about 9 yrs  then they get old about 10 mins before they die aged anywhere from 15 - 21 yrs.    Some bloodlines show their maturity earlier than others my American bloodline male was going grey under his chin about 8 yrs old whilst our European line didn't show grey until 11. 

Friend has a 15 yr old who got past her out the gate and trotted down the street ignoring her all the way took 3 folk to catch the old b, vets says he's deaf we don't agree coz he can still hear a crsip packet from 50 paces gets on the picnic bench shoulders all the youngsters off and stands like a dream!

People always think my oldest girl, because she is a little smaller is the puppy.  dogs with black muzzles often get a bit of grey as early as a year, but I do not view this as a sign of ageing.

For me ageing is the deterioration in mobility and body systems, and to some extent behaviour, but this is related to these.

So I notice the first signs of less muscle mass, less wasteful exercise etc not before 10 years in my breed.  I expect to see my lot taking their usual exercise etc until they die, but once they reach say 10 they will not rush around and use themselves up the way the youngsters do.

Certainly until two years old they are puppies, reaching full social and physical maturity at around four, are in their prime I would say until about 8, though veterans winning over younger dogs is common in the show ring and in Norway dogs would normally be hunting to at least 10.

> certain breeds age in mobility

My 16 year old toy poodle can still do a standing jump to my shoulder.

Jean thats brilliant, maybe the jumping is a Toy Poodle thing, as one of my best pals has a Toy Poodle and she jumps up to her shoulder, she's such a live wire and its really amusing to watch her, she does non-stop jumping and it looks like she's bouncing on a trampoline :-D

Having had giant breeds for years, I always notice a difference around 4/5 years of age.  Seem to start ageing quicker then!  (know the feeling)
