Red ONLY here, picture description are the same product but the product is Red ONLY!! SIZE M: Chest Girth is 17.3"-23.4", and the width of this dog harness is 0.75". Please measure your dog’s size carefully before purchasing. Our training vests can be adjusted in length under the chest to fit your dog's size, allowing your dog to be more flexible and comfortable when walking and running. NO PULL DESIGN: There are 2 metal D-rings on the back of the escape-proof dog harness for leash connection, which can evenly distribute the pressure during daily walking or training, and reduce the risk of choking. PERSONALIZED ID TAG: You can write your dog's name and your number on this ID tag, so this would be helpful to find your dog if it gets unfortunately lost. Of course, you can remove the ID tag and replace it with any little accessories you like instead. SizeDURABLE MATERIALS: The heavy-duty step-in dog harness is made of superior nylon material with reinforced stitching. It will not break even during high-intensity outdoor sports or training, and the lightweight and the breathable feature will not make the harness a burden even in summer. SAFER AT NIGHT: We use reflective threads to make the harness for dogs easier to be spotted when walking at night. The reflective dog harness allows drivers enough time to react to avoid danger and tragedy.
