Heya! I'm struggling with training my 7 month old lab, Rocky. The only command he knows is 'SIT'. He jumps a lot and does not listen. I am worried that he might end up hurting someone as a result of jumping. Because of work, I struggle to train him on a daily basis. I read that in order to stop him from jumping, I should walk away and ignore his actions but this hasn't stopped him. He also tends to 'playfully' bite when I try to hold him or pat him. Please help! Thanks
