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.
Cavalier King Charles Spaniel Considerations
This is a "Velcro dog" in the truest sense. They were bred to warm laps in drafty castles and have not lost this biological imperative. They cannot be left alone for standard workdays (8+ hours). Isolation leads to profound distress, destructive chewing, and incessant whining or barking.
While they are toys, they are still spaniels. They retain a prey drive that can be triggered by birds, squirrels, or butterflies. This "arrested" predatory sequence means they may suddenly bolt into traffic if not leashed, despite generally good recall.
