I tell my blind dog to get ready to tell the world you are blind and he knows we're going for a walk or a stroller ride! He LOVES this on his body. The mesh material breaths well and if fits perfect! He feels much more secure in it and when it's on him, he knows it's park time! The leash it comes with keeps him close to me and it gives him a great deal of confidence! He trusts walks MUCH more since I bought this....And this is my second! It's been quite the asset in re-training him!  My only wish is MAKE IT IN MORE COLORS!!! WHITE GETS DIRTY!! Give a blind dog owner some choices!
