Training
Black Russian Terrier
- s, which can trigger defensive aggression. The ideal approach is **firm, fair, and consistent leadership**. You must be the one who initiates and ends activities. They are "pushy" and will test boundaries constantly [cite: 1, 22].
Bullmastiff
- ** Positive reinforcement is the only viable path. Harsh corrections often cause this breed to shut down or become defensive.
Bullmastiff Considerations
This is a genetically rooted trait in many Bullmastiffs. While they may coexist peacefully with dogs of the opposite sex, placing two males or two females together often results in severe conflict once they reach social maturity (18–24 months). This aggression is rarely "cured" through training; it is managed.
Bred to track and hold poachers silently without human direction, the Bullmastiff is an independent problem solver. They do not have the "will to please" of a Golden Retriever. If a command does not make sense to them, they will simply ignore it. This is often misinterpreted as stupidity; it is actually a refusal to perform rote tasks without high-value motivation.
While independent in thought, they are physically clingy. They will lean their 120-pound bodies against you, sit on your feet, and follow you from room to room. This constant physical presence can be overwhelming for owners who value personal space.
