Cavalier King Charles Spaniel vs Irish Wolfhound

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.

Despite their calm demeanor indoors, these are powerful hunters. Their prey drive is triggered by movement. A squirrel, cat, or small dog running across a field can trigger an explosive chase response that is nearly impossible to stop with verbal commands once engaged. They are generally with small running animals unless raised with them, and even then, instinct can override training.

Wolfhounds are deeply bonding "velcro" dogs. They do not thrive in isolation and can suffer severe separation anxiety if left alone for long periods. This can manifest in destructive chewing, which, given their jaw size, can destroy drywall, furniture, and doors in minutes.

Between 6 and 18 months, a Wolfhound is essentially a 100lb+ puppy with poor coordination and high energy. They can be mouthy and destructive. Their counter-surfing ability is unmatched; they can reach the back of kitchen counters without lifting their paws off the floor.
