Mt 55 pound spoo get very excited when he sees people or dogs, deer, etc. He lunges, bolts, pulls and my joints are wearing out trying to contain him. I took him to teenage puppy school and by the fourth class he could sit, social distance, with the other three dogs, but he was by far the most crazy to be with everyone else, I’ve had a trainer come to the house, and I have completed an on line boot camp for reactivity. My question is, since he is sooooo social, should I be taking him to daycare to play? My trainer is all about making sure I am the most important thing in his life, but I need something to relieve his over excitement So we can leave the house on a leash without either one of us getting hurt. I’m wondering about a harness, or maybe some encouragement that he will outgrow this as long as I am consistent with the training?
