Only American lines have cardiomyopathy / only UK lines have aortic stenosis so aren my dogs safe?
• If only it were that simple! Unfortunately this is simply not true. My own experience of cardiomyopathy in New Zealand was from purely British lines back many generations. The problems may have a higher incidence or higher awareness in particular countries but all boxers started from a common gene pool and the genes for these life threatening problems are all countries.
