Cairn Terrier Considerations
This breed possesses a (see Section 15). They were bred to bolt, chase, and kill vermin in rock piles (cairns). This means they cannot be trusted with hamsters, gerbils, rabbits, or birds. This is not a training issue; it is a genetic feature.
Cairns are vigilant watchdogs. They will announce every delivery truck, squirrel, and passerby. In shared housing (apartments/condos), this can lead to noise complaints if not managed early.
Their large front paws and strong nails are designed for excavation. A bored Cairn left alone in a yard will landscape it, often digging under fences to pursue prey.
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.
