The EzyDog Neo collar is made from soft neoprene, the same material used in wetsuits, and reinforced with nylon webbing for extra strength. This material is easy to clean, quick to dry, and waterproof. It is also non-porous, which significantly reduces the odor that traditional collars often retain. The collar is further reinforced with EzyDog's proprietary soft touch nylon webbing for added strength and durability. Like all EzyDog collars, the D-Ring is made from stainless steel to prevent rusting. The Neo collar also features a hook and loop adjustment, a quick-release buckle, a separate ID attachment, and reflective piping for enhanced visibility and safety during nighttime. It's a safe and comfortable choice that your dog is guaranteed to like.
