PRA cases by sari

Announcement from the Swedish FCR pages:

As many of you know by now several cases of PRA has been diagnosed in dogs with one and the same owner in the Netherlands. It could be as many as 5-6 cases during appr.8 years, most of them during the last 5 years.

Some questions have come to mind regarding this:

• Could it be an acquired form of PRA?
• Why only males?
• Why such a concentration of cases with one owner?
• Why only imported dogs (Switzerland and Sweden)?
• Why no cases in littermates/parents (so far)?
• Why not in combinations which are very much the same as the PRA cases or are similar?

These questions have caused us to consider that these dogs do not suffer from the “classic inherited” form of PRA as so far no littermates, progeny or parents have been diagnosed. Neither has this happened in lines with similar pedigrees or combinations of lines from those diagnosed. Far from all are examined but so far none of the littermates have got the diagnosis PRA.

We are considering inheritance, environment, parasites, toxicity or any other plausible cause.

A great number of experts in Sweden as well as abroad are involved in this and are very helpful regarding these thoughts.
