How the breeds were chosen

We chose the breeds with the greatest height at the withers or weight in the breed standard (FCI or, where noted, AKC), as shown in the physical table on each breed’s page. The values are for males; females are usually smaller. Large dogs usually live less long than small ones and need space and food to match.
