Rottweilers are one of the most popular dog breeds in the world. They are powerful dogs with strong jaws, primarily meant to protect. They generally don't like strangers and other dogs and if they think their owners are in danger, they can be very dangerous. Rottweilers are now used as search and rescue dogs, as guide dogs for the blind, as guard dogs or police dogs, and in other roles. Rottweilers are a powerful breed with well-developed genetic herding and guarding instincts. Potentially dangerous behaviour in Rottweilers usually results from irresponsible ownership, abuse, neglect, or lack of socialisation and training. Origin: Germany; Weight: 85-110 lbs; Height: 23-27 inches.
