[quote=gsicard]4. Does this dog have rules, boundaries and discipline in the home? Behavior?[/quote] Lets try this one again but first please understand that you are not being judged here. There are many knowledgeable members here and many Neo owners also. Fully understanding your situation will enable us to help you. Most of the large Mastiffs and Guardians tend to be boisterous puppies unless they are shown the rules early on. Many owners make the mistake of accepting goofy behavior from a puppy and then are surprised a few months later when the no longer cute puppy is a challenging adolescent. Behaviors not corrected early are somewhat more difficult to correct later - difficult but not impossible. If you do intend to keep the pup (and fiancée :oops: ) you may follows Frank's suggestion and seek out a trainer who is familiar with the Neo or Mastiff breeds. It is always best to start out with absolute rules of behavior and boundaries in the house and then to relax those as the dog matures and can make better judgment. One absolute I would not put up with is any of my dogs showing aggression towards me or other family members in the house. The correction would be swift, painful and memorable. I also do not allow running, playing or boisterous behavior inside the house. All dogs MUST be calm inside the house. The house is my domain. Dogs stay downstairs, off the furniture, out of formal rooms and basically can be in the living room area only. The rules are set and they know it. Breaking the rules results in punishment and banishment to some other place (outside, kennel, garage). Your dog needs some urgent help because it is at the stage when the temperament is being constructed and firmly implanted. You must be careful not to crush her spirit and make her fearful but must also give her some rules before you have to give her up. I don't think she will outgrow the behavior unless it is corrected in her head first. By posting here and asking - you are on the right track and I hope you are able to get the proper help. Your are to be commended for asking as most Neo owners would not have the nerve to ask for help for fear of the Neo community descending on them. Good luck.
