If a dog is hip scored at coming up to 3 yrs old are the results likely to be worse than if it was done at a year?

Only if the hips are not brilliant.

If the hips are good to start with then there will be very few arthritic changes due to age.

Litter brother and sister that I bred sis Hip Scored around 18 months,a and brother not until over 5, his score was almost identical to hers in every way (break down of the features), just one point difference.

Yes, agree, good hips remain good, poor hips will develop some calcium deposit. Had a bitch scored at 7 and she was still within the breed norm.

In my country of origin you were not allowed to get hips scored until the dog is two years old so I would imagine 3 years old should not have much of a difference.
If anything it will give more true picture of the status of the hips and what can be expected in the future.

They also say scoring at 1 year old can have negative effect as the dog is not fully grown(giant breeds).
I know of dogs that have been scored at 18 months (youngest you can now score) and the hips have been "loose", re-scored at 3 years and the results have been better as the dog has matured and fully grown. Of course if the looseness does not tighten the results will be worse as the hip will have wear quicker than a normal hip would.

My current girl was scored at 2.5 years (due to having an serious accident at 15 months) and her score came back 0/4...
4 being on the side that took all the pressure after her accident.

Thanks, that's pretty much what I thought :-)

Is that just in your breed Noora? I know of a bitch x rayed on 20th of July this year, a day after her 1st birthday.

I don't think Noora's talking about the UK. Here it's from 12 months, and can only be done once; they cannot be rescored later.

Yep, not talking about UK sorry should have said this...
In UK you can only submit one set of xrays for scoring but in Finland you can get a new set done so can get official scoring for a young dog and same dog few years later if you feel the hips might have changed (only the latest score will be official, wether it is better or worse)

I like this idea.  It may provide useful information for breeders, but it also answers the question for owners who might wonder if a rescore may be better.

Does anyone know why this isn't the case in the UK or if this has ever been officially asked for?

Had one of my girls hipscored at 6.  From 6 months she was able to jump almost 6 foot in the air and nothing I did would stop her bouncing.  Her hipscore came back 6/4 total 10.  Just hoping my mental pup at the moment has a good hipscore as she dives on and off everything.

I had my 2 litter sisters hip scored at 12 months old and they were quite low score. Their other litter sister was done at 5 years old, and she had an even lower score than the other two :)
