Alfie Couture Designer Pet Accessory - Mon Dog Collar and Leash Set Please note that this listing is for size: Medium. Collar is 0.5" wide and best fits pets with neck size 10.75" to 12.25". Leash is 46" in length x 0.5" wide. How to measure your dog's neck size: measure around the neck close to the shoulder and allow room for a comfortable fit. Sizing for each dog is unique. Similar to our clothing and accessory, medium size from one designer is not the same for another. For example our 9-pound yorkie model usually fits either one of three sizes (i.e. XS, S, M) depending on the designer. We highly recommend you measure your pet precisely with a flexible tape measure to ensure the best fit. Contact us if you have question. We are happy to help. Crystal encrusted buckle for the collar. Sewn in loop handle for added comfort and control. Comes complete with a matching leash. Feature a sturdy D-ring for easy leash attachment and a beautiful puffed paw charm. Perfect for everyday walk and weekend party, or just making your pet look its best.
