Hi Zahed. Cases like this are difficult to comment on, because although I can say that the behaviour you describe is more common in entire male dogs than neutered ones, in any individual case it’s impossible to be so certain. I would in fact neuter, and you will hopefully be surprised by how little things change. Unfortunately, that will probably also be true for the behaviour of concern, but it’s worth trying given the potential consequences of it worsening. I would strongly suggest you simultaneously engage your wife in the training program if it all possible so that your dog also begins to see her as a leader together with the hormonal change.
