My brother recently acquired a dog from his neighbor. He is we think a bermese mountain dog mix possible with rottie or akita, or both lol he is 1 yr old and has been tethered all his life. drake ended up hung up on his fence so my brother went and got him and has had him for 2 days now. Drake has not one mean bone in his body, and his jumping (which was hard to deal with because of his sheer size) is no more (he's been around 3 well behaved dogs, i think that's why he decided he has no need to jump). However, walking him is another story. He seems to have it embedded in his mind that once a leash is on, he pulls and that's what you do when a leash is on. How can we break such a large, determined dog of this bad habit? He is not neutered and I suppose that could be part of the problem but is there anything we can do while he is not neutered? I've never trained a dog like this to walk on a leash, so I don't know where to start.
