This harness allows for adjustment around the chest to fit your dog's breed. The back buckle is easy to put on and take off, and won't hinder movement during daily walks, dog park visits, or activities like agility training. Reflective material is used on the edges, making it ideal for nighttime walks. The material is lightweight, durable, non-allergenic, water-resistant, quick-drying, and easy to care for. 【Material】Natural rubber, PVC 【Country of Origin】Italy 【Color】Red 【Size】1 I used this during my puppy's early months, but I'm selling it now that I've bought a new one. I purchased it about six months ago, but only used it for about two months. The condition is good, with no noticeable stains or scratches, but please understand that it is not brand new.
