Just to note, have been told this is not a study limited to UK breeders, but is open to international participants (Dr Rusbridge titles it an international study for her blog post. So anyone interested in participating internationally should contact researchers.
So far there is the ability to do the measurements in the UK (so irish breeders could travel); Australia and at least some of Europe. There would be hope to get someone also in North America I would suspect.
