Bichon Frise vs Great Dane

Bred for centuries solely to be companions - genetically wired to be with humans constantly. Cannot tolerate being alone for more than 2-4 hours. Isolation causes destructive chewing, self-mutilation (licking paws raw), and relentless barking.

Notoriously difficult to house train - small bladder and stubborn streak. Many owners report accidents well into adulthood. Expect 6-12 months to be reliable, compared to 3-4 months for most breeds.

Professional grooming required every 4-6 weeks at $50-100 per visit ($650-1,200 annually). Hair grows continuously and mats easily. Skipping leads to painful matting requiring shave-down.

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.
