I have a 9 month old puppy who weighs 125lbs. While I love him so much and I want to enjoy him I am finding it difficult because he does not listen and is constantly jumping on me or trying to play bite my arm. While he has never be "aggressive" towards me I can not help but to be intimidated by him because of his size. When we go on our dily walk he will try to bite the leash and will jump around me and try to get the leash out of my hand. He seems to listen more to my husband more than anyone. I have two sons under the age of 13 and it is not that I am fearful now of him hurting them on purpose it is the fear of what if I can not get this under control and something ever did happen to them or myself while my husband is working. I am new to this forum and I really am just looking for any sort of training guidance or recommendations so that I can love my furry baby more than I already. I am planning on getting him in to some puppy training in hopes it will train me to train him but if any one has suggestions on here I would be happy to hear them.Thanks,The Mother of a very large Mastiff Puppy http://www.mastiff-forum.com/images/smilies/pray.gif
