| My opinion is that you should consider yourself lucky that he is friendly with people! Keep him that way, don't hide him and make him unused to people.
To keep robbers out, how about a house alarm system? And you could add teaching him to bark if the house alarm or smoke detector goes off. If you want to do actual protection training, if you post your location, maybe someone will know a good trainer in that place. But beware of bad trainers and systems.
I give my dogs raw meat bones because I think it is good for them, but not to make them protective.
You probably need to not let him offleash at park if he is aggressive with other dogs. It will only cause both of you trouble. Is there a safe place where he can get exercise alone or only with carefully selected playmates who he can get along with? (Usually they do best with opposite gender dogs) |
