On this page you can find plenty of information about great danes. Many infos are links to the website of the Association for Healthy Great Danes which I founded in 2018 together with other breed enthusiasts.
Life Expectancy and Frequent Causes of Death
The average life expectancy of the great dane is only around 6,5 years, while the most frequent causes of death are cancer, stomach torsion and heart diseases
The look of the great dane has changed immensely in parts of Europe in the last 30 years. The breed has deliberately been changed into a long-legged Mastino. This destructive hypertype trend has to be stopped.
