Hello, new here and a new rottie mum to Sabbath. He is a 4 month old German rottie, and he's rotten as hell. I'm not sure if it's just the pup in him or he is just freaking mean..! He treats my kids and I like a chew toy. I tell my kids dont let him do that, to get a toy and play with him. Other then that he's amazing and smart , super smart. I don't want a aggressive dog at all , PLEASE HELP...!
