my pup,Nimz who will be my traveling companion when the time comes ..is not very socialized...any suggestions to help become friendlier to other dogs..he has only been with his brothers up to this point but as they will be staying with my brother here....I want to be able to have him with me in many social situations I may come across without worrying about him...he is young ,yet just 18months and is being neutered next month...I ,of course do not have the funds to take him to obedience school (he does know the basics well)and there are no dog parks close by.<br>how can I teach him to be friendlier but still protective enough of "home" when we are not around other people.....Or am I just worrying for nothing?
