I mean, have you ever seen anyone successfully loose leash walk their dog using a retractable leash? I observed a man yesterday at our local pet food center trying to control his medium sized dog while another customer was walking their very petite pups. Guess what he was using? A retractable leash, that malfunctioned, the dog was able to get far enough away from the owner that he lost control and the dog went right after those little puppies. Luckily, the dog just wanted to say hello, and those two little pooches knew exactly how to take care of themselves! This scenario could have turned out pretty bad.
Or maybe, you have an older dog that walks you instead of you walking him. He pulls you all over the place, chases the neighborhood cat into the thorn bush up the street that you are now well acquainted with, and it seems like any time you pull back on the leash, Fido increases his speed! You decide he’s getting too big or too strong for you and before you know it, you are in traction at the chiropractor and your beloved pup is getting fat on the couch!
