It's easy to tell apart male and female Old Danish Pointers. The former are powerful and solidly built, the latter lighter, livelier, and more impulsive.
About the Old Danish Pointer
Old Danish Pointers are members of a calm breed of steady character, with plenty of determination and courage. These medium-sized, rectangular dogs are strongly built.
The origin of the breed can be traced back to around 1710 when a man named Morten Bak, through eight generations, was crossing gypsy dogs with local farm dogs and in this way established a pure breed of piebald white and brown dogs called Bakhounds or Old Danish Pointing Dogs.
