Hi everyone I’m new here and I have just recently adopted my first dog. He is a 5 month old lab/pit bull mix and he is really coming out of his shell! He is very playful but he has started “play” bitting and he does not know his own strength, he could easily break skin. I feel like he is testing my limits and being an angsty teen. I have him outside before I head to work during my lunch break and basically until we go to bed around 9 but he still seems so full of energy. Any and all training tips would be much appreciated!!!
