Can we talk harnesses please all? Specifically those that can help with pulling? Oreo is nearly a year old and i still have issues with the pulling. I've looked into Perfect Fit and Mekuti which i've read from training sites are recommended but they are a bit expensive. Can anyone recommend any other harnesses? I had also thought of a head collar but i can't see Oreo (my cocker spaniel) coping with that well Thanks in advance for any advice.
