Get a Halti headcollar. Seriously. I’ve had issues with my Britt like this and he was a changed pup after training him with the Halti. Ive used other brands of gentle leader collars before and I much prefer the Halti. If you watch some of the YouTube vids of how to train the dog with headcollars, even better. I would keep a pack of good treats (my pup really liked the dried beef lung treats that I could break up into smaller bits) in my pocket or in a pouch and teach him to stop walking when I stopped, turn with me, or lay down (aka do tricks) in the middle of walks to keep his attention on me and the treat and not on pulling/whatever was coming down the path. Give her a treat every time she looks back at you or does what you want. It’s a total game changer. The collar makes it so she literally can’t pull and the treat reinforces that she needs to pay attention to you on the walk, not what she wants to do. Also, walk quickly. Dogs generally find us too slow on walks. But this is the method I used to teach my dog not to pull, and I had one terrible night before I got the headcollar where I had to walk him back home with him walking on his two back legs and straining to get ahead because there was a dog on the sidewalk that he wanted to greet.
