Great Dane vs Great Pyrenees

Great Danes are profoundly social animals, often described as "Velcro dogs." They do not tolerate isolation well. Left alone for long periods, their anxiety can manifest in destructive chewing or digging. Given their size, a panicked Dane can destroy a door frame or a sofa in minutes.

While generally calm indoors, young Danes experience bursts of frenetic energy known as "zoomies." In a small space, a 100lb puppy moving at high speed is a physical hazard to furniture, children, and themselves.

Between 6 and 18 months, Danes are essentially giant puppies. They may not realize their own strength, leading to accidental knocking over of children or elderly family members. Leash manners are critical; a pulling Dane cannot be physically overpowered by most owners.

The #1 complaint from suburban owners. Pyrs are genetically hardwired to patrol and bark at night - they were bred to ward off wolves and bears. This instinct cannot be trained out, only managed. Expect deep, booming barks at 2 AM when a leaf blows across the driveway.

Great Pyrenees do not believe in property lines. Without a secure 5-6 foot physical fence, they will expand their territory to include the entire neighborhood. They are notorious escape artists and will take the shock from invisible fences to pursue threats.

Adult Pyrs often exhibit severe aggression toward dogs of the same sex, particularly females. This usually manifests around social maturity (18-24 months). Opposite-sex pairs are generally recommended.

Pyrs are not dumb - they are independent. When called, they evaluate whether coming is more important than what they are currently doing (usually guarding). If they decide it isn't, they will ignore you completely.
