This is a great video with training tips on how to get your dog to stop pulling on the leash. I would have loved to see this woman use a medium or larger breed dog, but the message is still clear with the tiny dog that is pulling ahead.
Pulling is easily corrected once your little one establishes a relationship with you when you are on the other side of the leash. Is your pup at your heels in the house, but then drags you around town once you get to the street?It is important your dog keep a connection with you by glancing up, feeling when you have stopped or turned around, and not getting to far ahead (tense leash). Once a connection is established, some light training can change tho whole dynamic of your daily walk!
Enjoy!
