The comfortable shape distributes the pulling pressure on your pet\'s chest to reduce the stress and burden on their neck. Large sizes (M L size) add a snap design to prevent adult pets from breaking free, and small sizes (XS S) do not require a snap, enabling better care for small cats and dogs. 360-degree wrap-around reflective strip to enhance pet visibility in the early morning or evening. Fastener tape design on the back and adjustable clips provide a comfortable environment. The aesthetically pleasing and comfortable leash is also comfortable to hold for a long time and is very resistant to pulling. Two colors and four sizes are available to meet your different needs, whether it is an adult dog or cat or a young one, there is a suitable chest and back.
