Boerboel Considerations
This is a primary failure mode. Many Boerboels, particularly males, will not tolerate another dog of the same sex in their household once they reach sexual maturity (18-24 months). This aggression is often sudden and severe.
Unlike a Golden Retriever who welcomes burglars, a Boerboel is naturally suspicious. Without extensive, ongoing socialization, this suspicion can escalate to fear-aggression or liability-inducing protective behavior.
Their dominant nature makes them prone to guarding food, toys, or even their owners. This requires an experienced handler who understands how to manage resource guarding without confrontation.
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.
