Can't take dog for walk

Question:
 I have a 1 year old dog that is half pit and half ? and can't take him anywhere. He jumps our fence so I have him on a chain inside his pen. He won't bite but scares the neighbors to death. When I put him on his leash to walk him, he drags me everywhere. Most of the time I end up running to try to stay up with him. By the time he gets thru dragging me around the block, my whole body hurts. I have tried everything to stop this behavior. Nothing works. I need help so that he doesn't have to stay in the pen all the time. Any advice would be appreciated.
Answer:
 I have used this method without needing chokes or prongs and with EXTREME effectiveness with Pits, Am Bulls, etc. Using it currently on a Rottie and a Rottie cross. Also for the fence, SIX FOOT is needed for a pit. Sounds like you have a four foot as well as a yard the dog finds boring. Anyhow, check this link for ther Art of Loose Lead Walking: http://www.petpeoplesplace.com/Care/Dogs/003/27.htm This on dominance issues and how we idiots can cause our dogs to react more... http://www.westwinddogtraining.com/Articles_Etc/Training/Dominance/dominance.html And read this on leash lunging, desensitizing and tolerance building (from my class manual). "A big complaint of dog owners is that their dogs or even puppies lunge at things while out on walks. Regardless of the size of dog you have, lunging needs to be stopped. Part of having a well-mannered companion is having one that has solid leash manners at all points in time. I have watched dogs actually drag children into busy streets. Therefore for safety reasons, no child should ever walk a dog without a responsible adult present. There is just too much that can happen. If your dog lunges at things while walking, he needs to build up self-control or even self-confidence in how to behave. This is going to mean YOU need to teach him that. Along with teaching walking on a loose lead, we have to teach dogs to tolerate things around them. You are going to have to watch your dog closely and learn what body language he exhibits before he starts lunging. It will vary dog to dog. Some may be very overt while others may only give a flick of an ear or a change in stance. This is where owner observation and understanding of the individual dog owned is vital. Every dog has a threshold between not lunging and lunging – this is the point where the dog is still voice responsive and shows interest in you and the thing he may lunge at but has not started and actual lunge. It is vital that this threshold not be broken. As soon as a lunge starts, you have lost control of the exercise and need to start again. Punishing this is futile, builds stress and anxiety and since it is your fault for not watching the dog closely enough and backing off before the lunge, not fair. It can also encourage the dog to lunge more for a few reasons including you are being not fun or even mean or since you are reacting negatively to the thing, it may be a threat. Remember, you are the one teaching tolerance and building up that threshold. You need to reduce stress levels in the dog; punishing does not do this. Have the dog walking with you under control. When you see something the dog may wish to lunge at, start to gain the dog’s attention. As long as the dog will focus on you and work with you, start to slowly approach the thing. Watch the dog carefully, when he starts paying more attention to the thing and less to you but is not lunging yet STOP! Get the dog eve more interested in you, do some fun training and gain full attention for a few moments, praise and walk away. Next time try and get a bit closer. Always stop the exercise when the dog is paying attention to you and things are fun. Eventually, you should be able to walk close to the thing and the dog not lunge. Note: If you have to walk past something you know will cause a lunge, shorten the leash up tight to you (do not hang the dog, but give the dog no extra slack either). Start getting the dog to focus on you by using silly voices, treats, toys, etc and walk past QUICKLY without stopping. The dog is not ready for this level of closeness yet, his tolerance is not built up enough and you need to get in and out as fast and as positively as possible."
Answer:
 Thank you ever so much for your advice. I will try this as soon as I take him out again. Tammy
