I need help leash training my two beagles Bo and Luke (they're over there <--- in my avatar). They both pull like crazy until they get tired, then Luke continues to pull. They stop when I stop and won't try to run when I'm not walking, but as soon as I start walking, they pull. Because of this, I put them on an EXTREMELY short leash (about two feet) when we walk, which means they are ALWAYS at the length of the leash. Luke pulls so much that he is constricting his airway, but he doesn't seem to care about that. I would imagine I need to take them out one at a time so that they don't get distracted (though, really, they don't really pay much attention to each other) and so I can control them easier. I have also heard that a muzzle leash/collar will help to control them until they get used to doing what I want them to do. I understand I have to change something, just let me know what I have to change.
