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.
Saint Bernard Considerations
Despite their size, Saints are profoundly needy. They do not tolerate isolation well and can develop destructive separation anxiety. A 160lb dog with anxiety can destroy drywall, doors, and furniture in minutes.
While benevolent, they are not blindly obedient like a Golden Retriever. They possess a slow-burning stubbornness; if a Saint Bernard decides not to move, you cannot physically force them. This requires patience and psychological motivation rather than physical correction.
Between 8 and 24 months, they are essentially giant, clumsy puppies. They can unintentionally knock over children, grandparents, and furniture. Leash manners must be solidified before they reach full weight, or they will become dangerous to walk.
