Jacob Morgan explains how repetitive ball throwing can heighten a dog's arousal and prey drive instead of tiring them out. He argues owners should judge activities by the mental state they create, not just physical exhaustion.

If all the dog is doing is chasing the ball, grabbing it, running back, staring at you like a crackhead, and waiting for the next throw, that can become more like an obsession than a healthy fulfillment. Their body gets tired, but their brain gets more switched on. They practice explosive movement, they practice fixation, they practice scanning for the next throw, they practice going from 0 to 100 over and over again. Then later on a normal walk, that same dog is sharp, twitchy, and ready to chase the next bit of movement. Bike goes past, a dog moves, a child runs, a bird takes off, a car passes, and the owner says, 'I don't understand, I tired them out before we came here.' But tired is not always calm. That is one of the most important things reactive dog owners need to understand. A dog can be physically tired and still mentally frantic. A dog can be exhausted and still unable to settle. A dog can have loads of exercise and still be in the wrong state. So the better question is not just, 'How can I tire my dog out?' The question is, 'What state does this activity create in my dog? After chucking the ball, does your dog look softer, calmer, clearer? Are they easily able to settle, or do they look more intense, more demanding, more restless, and more easily triggered? That tells you a lot. For some dogs, especially dogs with strong prey drive or those who already struggle with arousal, endless ball throwing can just pour fuel on, onto already burning fire.
