Bolognese Considerations
This is not a breed that tolerates isolation. The Bolognese was bred exclusively for companionship for centuries. They do not have a "working" mode that allows them to be independent. If left alone for more than 3-4 hours regularly, they are highly prone to severe separation anxiety, which manifests as destructive chewing, house soiling, and distress vocalization.
Unlike the gregarious Bichon Frise, the Bolognese tends to be more serious, reserved, and shy with strangers. Without early, positive socialization, this reserve can turn into fearfulness. Furthermore, owners often baby them due to their size, leading to "Small Dog Syndrome" where the dog becomes neurotic, demanding, or snappy.
Like many toy breeds, the Bolognese can be difficult to house train. Their small bladders and a tendency to be sneaky about accidents require patience and consistency. They may regress during adolescence or if the weather is poor.
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.
