Cane Corso vs Keeshond

Even well-socialized Corsos often develop intolerance for dogs of the same sex upon reaching social maturity (18-24 months). This is a breed trait, not a training failure.

Unlike breeds that welcome intruders, a Cane Corso is naturally suspicious. Without extensive socialization, this escalates to fear-based aggression or liability-inducing reactivity.

This is a guard dog, not a watchdog. They will physically block or confront threats. Requires an owner who can call the dog off instantly.

Resource guarding (food/toys) is a known trait that must be managed early before it becomes dangerous with a 50kg+ dog.

This is not a dog for a household where everyone is gone 8-10 hours a day. Keeshonds were bred as barge dogs, living in tight quarters with their captains 24/7. They are genetically wired to be with their people constantly. Isolation distress is common; a Keeshond left alone for long periods may bark incessantly, become destructive, or develop neurotic behaviors.

The Keeshond is a watchdog, not a guard dog. Their historical job was to alert the barge captain to anything unusual. In a modern home, "unusual" can mean a delivery truck, a neighbor walking by, or a leaf blowing across the patio. They are vocal and "talkative." While they are rarely aggressive, their piercing bark can be a nuisance in apartments with thin walls if not managed early.

The shedding is not a myth. They "blow coat" (shed their entire undercoat) once or twice a year, resulting in trash bags full of fur. Even outside of shedding season, their double coat requires weekly line-brushing (brushing down to the skin) to prevent painful matting. This is a significant time commitment.
