There are a few ways to teach a loose leash walk.
1) Be a tree.Give a happy "let's walk" & step off. As soon as he pulls, you stop. Plant yourself & wait. It may take awhile, but eventually the dog will want to kow why you aren't moving & will either come back to you, or turn his head to look at you. mark that moment..either with a clicker, or a word (i use Yes!) Treat the dog, then take a few steps. Repeat, repeat, repeat. It can take an hour to go 50 feet...that is fine. Dog learns pull=no walk. Leash is slack=we walk.
2) Teach dog to target your hand (or a stick if he is short). Say "touch", dog touches target..click/treat. Once he is reliable, fade the target & simply click/treat for walking nicely for 2 steps, then 3, then 4 & so on.
Any method you choose must be done consistently, by everyone who walks the dog. It will not happen overnight, but it will happen.
A great book for beginners to positive training is "The Power of Positive Dog Training" by Pat Miller
