My 9 months old black lab and I are attending training classes since he got all the necessary vaccines. The trainer uses mostly positive training methods, with some aversive ones which I just try to ignore. But lately she has been pushing me to get a halti for my biy, since he is pulling a lot more in the presence of other dogs. He is in peek adolescence and we had to take quite a few steps back in training which I don't mind. We went back to basics with basic commands, recall and heel work. I'm just quite annoyed with my trainer for pushing the halti on me and am reconsidering if i should continue attending classes at this time. Does anyone have an opinion or any advice as to how to continue with training? Thanks to all.
