Hi! Our family dog recently moved from my parents house in a small village to my house in the city. He is calm and very obedient in the house, but our walks are not very pleasant. He lunges and barks at other dogs and sometimes people, and I suspect that he is either frightened or frustrated because he wants to greet them. Or maybe both! I want to help him feel safe and protected when we're outside, and be in control so that he doesn't hurt himself or traumatize other dogs. I'm training his impulse control and ability to listen in low-stimulus environments to make sure he can keep his focus on me, but I'm uncomfortable to take this big (and STRONG) boy on longer walks as his focus gets lost even in the garden if a dog walks by. His pulling reaction is very unpredictable and he seems to og from relaxed to overly excited in less than a second. To make matters worse, my father has used a choke collar on him to keep him. I'm very opposed to this, but he can easily escape regular collars. I want to get a harness so that he doesn't hurt his neck, preferably a non-pull harness that will decrease his pulling strenght. It that a good idea? I realise, of couse, that he'll need time to get used to his surroundings, but I'm afraid that his reactivity will get worse. So, does anyone have any tips on how to deal with this? My first thought is (like I mentioned) that I should get a new harness that doesn't cause him further discomfort in his reactive episodes, and train with him in the garden only until he can deal with dogs passing our house before we try longer walks. I hope you can help!
