train him with either punishin him, or with food!!!!! and make him smart!

get a better dog

You should never punish a dog, it'll just make him worse. Use positive reinforcement. Hold a treat in your hand, spray the hose(my dog loves this for some reason),tell him he's going "bye bye". And when he listens tell him he's a good boy, give him that treat. Training a dog takes LOTS of patience, but if you stick with it you'll be rewarded in the end.

Your dog needs to associate his name with something good so when you call him he will come. Just randomly call his name and give him a treat several times a day. Just don't ever punish him for coming to you or chase him.

What about the invisible fence thing? I've heard those work.

I have the same problem. He's pretty good at it too. Looks real innocent and then all of a sudden he's gone. The only way I can stop him from doing it is to tie him up when I put him outside. I do that for about a week, making sure I take him for walks. He pouts quite a bit but that cures him temporarily. It works for quite awhile but it doesn't seem to be a permanent solution. Sooner or later the neighbours dog entices him back over there and then I have to start over again.

I would say, don't let him off the leash. I had one dog who would not go out of the yard or out of eyesight range of me and another dog that simply could not be trusted, so this dog always went out on a leash.

Why is he going to the neighbor's? Do you know? Maybe they've got some groovy cat food sitting out or they're feeding him table scraps. Sometimes if a neighbor is nice, they don't want to run your dog out of their yard for fear of appearing rude or nasty, but that is exactly what you need for them to do. Try talking to them & getting them to help you. They might not like your dog coming over & will welcome the "permission" to run him off.

If you discipline him or put him in a pen as soon as he does come back then he will associate coming back to you with punishment. Make it irresistable to come to you. treats, belly rub, a ride in the car, day by your side in the house. Keep him on a lead. Or get a fenced in yard. There is obviously something enjoyable at your neighbors. A chat with them to find out what could help.

Fence your yard.

If you house trained with punishments, yelling, and other negative things, you have a bit to over come as the dog may associate coming with unhappy events! If on the other hand you successfully house trained using positive reinforcements, you are off to a good start in your foundation/relationship for training MORE USEFUL THINGS! First ASSUME he is going to bolt and take action to secure him with his lead held by YOU. Teach him to sit or lay down and STAY, using positive reinforcement such as treats (really good ones...make it worth his while to listen, learn and DO the correct behaviors! I use human beef jerky..basic, plain cut into small bits 1 inch or smaller for a "jackpot" reward) or use his most favorite toy in the world...what ever you offer has to be at least equal or BETTER THAN what he wants to do that is "wrong." At the same time you are teaching him these commands and behaviors you teach him to COME. Make coming to you the most wonderful thing in the world...MAJOR REWARDS...you have to practice every day...even several times a day is good, for about 10 to 30 minutes...depending upon his interest and ability to focus. If he only focuses for 10 minutes to start pushing him won't improve the situation. But as he begins to LEARN...his joy in doing it will increase the time he is ABLE to do it correctly! ONLY practice and train in a SAFE SPACE, a fenced in space or in the house. Start with as few distractions as possible...you can add those later once he shows that he's "got it!" Lastly, NEVER put your ego as a trainer above your dog's safety. If it appears he can do the behaviors MOST of the time, but simply cannot manage to come to the recall 100%...don't trust him loose outside in an unfenced area. All my personal dogs have worked 100% on the mark off lead...EXCEPT for my current GSD/Husky girl, Hannah. She has that high Husky DRIVE to run off, and throw me a look over her shoulder.."come on yourself, catch up!" She may never be 100% reliable off lead in open space. Too bad, I'm not willing to put her at risk to try and prove that I can train dogs! Safety first, responsible dog owner second, fun for everyone! (you can buy a 15 to 25 foot lead to let them "play" and still be safe!)

look, unless you have lots of time and patience,you would be better off to try to find someone who wants him.take it from someone who knows,this situation can cuse hard feelings that can last forever.
