Seeing Eye Dog

I want you to meet Milo and Eddie. Eddie is a Black Lab and Milo is a crossbreed terrier. They are best friends and spend all their time together. But the cool part is that Milo is Eddies seeing eye dog. Well it is not official but ever since Eddie's eye sight started to diminish Milo has acted as his eyes in the world. That is what being a best friend is all about...
