There are several steps you can take to get your dog to stop pulling on the leash. First, make sure you're using dog treats, whether during walking or leash training. Second, make sure the collar or harness isn't too tight and the leash isn't too short that it is pulling on your dogs. Third, be sure you're using the right equipment. Sometimes, your pooch may get distracted by squirrels during walks and starts pulling on the leash. If this is the case, turn them away from distraction. If this is regarding regular dog walks since you have trained your pooch to walk on the leash, it may be a good idea to use a retractable dog leash because it gives your dog more space and room to walk and explore.
