Drag leads are anything but a drag -- think of them as stress prevention tools for both you and your dog. When your dog or puppy is attached to the line, you can let him romp and play while still maintaining control. Use it to easily interrupt problem behaviors like jumping and chasing, or soothe a frightened dog both calmly and quickly. This leash comes with its very own ebook (found on whendogstalk.com) that informs you how to teach an off-lead come and solve common behavior problems -- all while giving your dog the freedom he desires! It's 25' feet of pure magic!
