Kathy - I'm sure that Geoff Sampson wouldn't lie. He is a well respected Kennel Club Specialist and is prominent in canine health issues.
Of course as you say it could be an instance of breeders keeping quiet - how would we know either way? It would be really difficult however, to keep it quiet here as there are relatively few breeders in our small country and as you can imagine rumour is rife!!
When Dr Gonto came over to give his excellent talk on Fanconi here, Geoff was also present and spoke on Canine Genetics. He did have some questions to privately raise with Dr Gonto.
At that time Dr Gonto said that he had a few cases in the UK on his protocol.
I actually asked him why the Fanconi Syndrome instances were in proportion low here compared to USA and he said perhaps it was because of our low gene pool.
Of course since his visit the gene pool has been increased by the import of several overseas Basenjis for one thing, and the linked marker test has become available.
In my opinion it is difficult to get breeders to talk about all health issues here. One of our reasons in inviting Dr Gonto here was to widen our knowledge of Fanconi. Our Breed Council had surplus funds and it was my suggestion that we put on a Health Seminar but this resulted in only Dr Gonto's and Dr Sampson's talk. There was little interest in a general health seminar and as it turned out this was not such a good idea as the take-up on the Fanconi one was relatively low.
Any way we're getting away from the thread a little.
I must say I agree with all that has been said and it is advisable imo to keep away from breeders who don't test whatever their reasoning.
