NO PULL DOG HARNESS DESIGN: This dog harness features a no pull design, and for dogs with a habit of rushing forward, the front D-ring can correct pulling behavior. Buckle the leash on the front D-ring, and when the dog is rushing fiercely, pulling the leash can make it turn in your direction, gradually changing the habit of rushing forward. The D-ring on the back can also be buckled with the leash, perfect for daily walks, running, training, travel, and mountain climbing. DOG HARNESS WITH HANDLE: This dog vest harness comes with a wide handle on the back, which allows you to control the dog closely in emergency situations, such as when the dog is trying to pounce on someone, chasing other animals, or crossing the road. The flexible strap of our dog harness can prevent the dog from choking when pulled by humans, making the force evenly distributed.
