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.
West Highland White Terrier Considerations
This is a true working terrier. They possess a high level of self-esteem and independence. Unlike a Golden Retriever that asks, "What can I do for you?", a Westie asks, "What's in it for me?".
Westies are vocal watchdogs. They will bark at doorbells, squirrels, leaves blowing in the wind, and delivery trucks. This is not a "quiet" apartment dog; their bark is piercing and persistent.
They were bred to kill vermin. They cannot be trusted with hamsters, rabbits, guinea pigs, or birds. This is a genetic kill-switch, not a training issue.
Westies generally do not tolerate rough handling. They are known to snap if pestered, pulled, or startled, making them a risky choice for families with toddlers who lack boundaries.
