Simply put, high-value dog-training treats are snacks your dog will go nuts over. Some dog trainers suggest using a low-, medium-, and high-value tier system for treat training. High-value treats are useful when teaching a dog a new task, or when you need to get its attention in a distracting environment like a training class or at the dog park. Pieces of chicken and beef count as high-value treats. Medium-value treats like jerky and soft chews, as well as low value treats like bits of dog kibble have their place in training, too.
