Scientific studies show that diabetes in Miniature Schnauzer populations was noted at an average of 34 out of 10,000 in the United Kingdom, 13 out of 10,000 in Sweden, and it was 19 out of 10,000 in the USA and Canada, with numbers increasing to 64 of 10,000 between 1970 and 1999. It seems to be a disease that is on the rise in Miniature Schnauzers.
