For Disc Dogs, performing a multiple (several discs thrown in rapid fire succession usually at a short distance and in front of the handler) can be a challenge. Multiples often lack a convincing catch, and this lack of commitment to possessing the disc can make the skill look like rapid fire misses instead of rapid fire catches.
While it is true that dogs do not generalize as well as humans, generalization may be enhanced through training. And the dog surely won’t be able to generalize unless they practice. Generalizing the spot behavior is critical to being able to use the skill successfully in our daily interactions. We need to be able to put our dogs in many different spots, as it is not practical to always have ‘your’ Spot with us.
