Start with a group obedience class, work toward getting his CGC. If he still has issues work one-on-one with a professional. You are lacking a lot of training experience, this will help.

I tried a professional one-on-one trainer once. It didn't really help him. I have taught him more on not pulling than I did with the trainer.

I don't want to sound cocky, but I don't know what a trainer would do.

maybe try a different trainer then? they can be pretty different

i agree with try a different trainer but if you insist on doing it yourself remember that being outside is a greater reward than anything you've been able to come up with, so you need to use that in your favor

You sound cocky. Also, you're wrong.

A vibration collar.

I wouldn't get too upset. This is exactly how 95% of dogs act.

You're taking him from a low stimulation area that's completely under your control, so he's a bit bored and everything you do interests him, including listening to commands. To a high stimulation area where there is a million different smells and noises. There's always going to be an issue of keeping his attention.

The best solution is just keep training him on the lead while you're walking. It takes time and patience. Also don't worry about the marking, that will be hard to stop.

Thanks for all the replies.

I'm going to call some places on obedience classes, and I am going to re-train him on our walks.
