The Rottweiler is a double-coated breed, with a medium length outer coat and a soft downy undercoat. They do shed their undercoats twice a year, in spring and winter. Rottweilers will bark to announce the arrival of people on the property, they generally don't bark without reason. Opinions vary on this topic. I recommend a female, especially for first-time owners.
Males are stronger, more powerful and dominant, and therefore somewhat harder to train and control.
