Australian Cattle Dog vs German Shorthaired Pointer

This dog was bred to nip the heels of running cattle all day, and a bored, under-exercised Cattle Dog will redirect that instinct onto joggers, bicycles, other pets, and children's ankles — it is not a mellow companion breed no matter how it looks in photos.

This is an all-day hunting athlete, not a jogging companion — a GSP that only gets a 20-minute walk instead of serious daily exercise and a job to do will reliably become anxious, destructive, or both, and that mismatch is one of the most common reasons the breed ends up in rescue.
