We all know that before even considering breeding Staffords should be eye tested as there can be a problem with HC/PHPV.
Before I go any further I am only raising this point for debate and I am not saying these tests are not required.
I have a list from the KC of all dogs eye tested.
OK a total of 2356 dogs were tested and only 27 were affected by either of the above.
I was just wondering at what level the decision is made that it is a problem in the breed.
Just thought it might be an interesting subject as Hip Scoring has been discussed.
For example one dog tested unaffected but he went on to sire 4 of the ones affected on this list.
So if your dogs are tested and clear it does not mean that offspring will not be affected???
It will be interesting to hear anyones opinions - not just on staffies by any breeds where any data is known.

Staffie
were only 27 affected because of the eye testing methods in the past meaning that it has helped address the problem if you see what I mean ?
Or have the figures through the last few years remained constant ?
I guess what i am trying to say is that have the figures got better throughout the last few years

The list I have has data going back to 1985 - not too sure when scheme was first introduced??
Earliest affected test result was 1993:
1 in 1993
1 in 1994
5 in 1995
2 in 1996
1 in 1997
4 in 1998
3 in 1999
4 in 2000
4 in 2001
2 in 2002
Earliest DOB of affected dog 1991 latest DOB 2001.

Hi Staffie

I have researched PHPV in Dobermanns which I understand is only slightly different to Staffies but in Dobes (and humans) two (apparently) clears can produce affected pups (babies).

Do you know how many SBT's have been registered/bred from since 1985 ( I don't think all the affected were published to start with, just the clears). Unless you can find a sire or dam where ALL the offspring have been tested the figures do not give a true picture.

In the UK I think we have had 5 affected Dobes reported with this disease that were picked up under the scheme. I know of more that were taken to the vet with eye problems but were not reported under the scheme. In Finland where most, if not all litters are tested the incidence of the disease is around 20% (I only pick on Finland because they test and tell and I have their results)

Oh, I did not know that only the unaffected were published back then. Glad the affected are published now though :-)
I just expected there would have been more affected but I guess your post explains why?
I do know there was one well used stud dogs on there that had produced two affected pups with different bitches one bitch also tested clear but the other bitch was not tested.
The above happened to another well used stud dog too.
But I suppose when you think of the pups produced by these two dogs the ratio of unaffected to affected is so much higher.
Still does all seem very confusing though. :-)

Thanks for that link I found it very interesting and informative.
I do have 3 dogs that need to be tested before breeding and wondered if you knew anywhere in North Linc that does the testing. We had our others tested at a local show but need to get them done sooner rather than later

Hi as to eyetesting someone i know has tested hers for years and never had any problems but a recent litter she has there is one that is affected and sadly will go blind she has all her pups checked at 8 weeks Ive been told that it dosent make much difference having your dog tested because it can come from nowhere but for piece of mind i think its best to have them done
