Our velociraptor is about 20 months. Like Paul said, when she is engaged upon a task, she is well over 100% focused. When there is no task at hand, she needs one. I wish we had cattle. We do have a rigid plastic ball, about 12-14 inches in diameter. That ball lives a hard life.
Mercifully, the velociraptor has something close to a 24-hour bladder. She drinks water like a fish, but doesn't need to go outside when I get up, or even when I finish my coffee and start the work day around 8. She's going to be a really good dog. She's trying really hard.
