The Shar-Pei breed originated from China more than 2,000 years ago. Why are they so wrinkly? | National Geographic

We are working on perfecting the heel command with Shar Pei named Blu. By stacking multiple training sessions back-to-back, the heel is becoming more effortless for the dog. The trainer, Josh, is carefully building the foundation and the dog is retaining the information well. They are also practicing the dog's ability to ignore distractions while heeling. Finally, they test the dog's ability to perform a down command outside of the training environment. | Julie's K9 Academy - Dog Training
