He could be suffering from separation anixety. When I am at home my dog does his own thing but when I go out for the day he follows my husband everywhere. The same hold true, if we are in the car. It is great until we slow down or stop, then he is jumping all over, crying and barking. Their fear of being left alone just takes over. Thats why many dogs destroy things while there owners are absent. Maybe you can reassure him by making him stay in a room by himself for a few minutes at a time, and then returning and praising him for staying there. Reward him with treats, this works for many dogs. You could also try crate training. You could leave him alone ,in his crate for short periods until he gets used to the idea that you will always return. Some people have had success with audio tapes. They put them on when they are absent so the dog feels more relaxed about being left alone. There is always the possibility of medication. My mother had to medicate her dog once only because he was making himself ill with pacing. The medication helped him control the urge to pace. It is best to consult a vet about your dogs behavior. They will be able to give you professional advice.

Your dog unfortunately thinks he's boss. We hired a dog trainer and he said that in doggy world the first one through the door is the leader. Put your dog on a leash and practice walking through doors- when he goes to run in front of you jerk him back with the leash until he gets that YOU are boss and YOU go first. Same with the stairs, practice that YOU take the steps first not him. If he drags you around on the leash when you take him for a walk this is also him being the boss. When he starts to lead jerk back on the leash to get his attention. You can also try abruptly changing directions so the dog has no choice but to follow you. Our dog did exactly what yours did and after doing what I advised above, he doesn't intercept our moves or butt in through the doors- but he DOES still follow us around the house. I think that's just some pack dog habit. I was able to teach him to "go lay down" if he is too in my business but for the most part he's still my shadow. Every dog's different you just gotta work with the personality they have. Good luck!

I think that dogs only follow you around the house as though they have no boundaries because the owners of these dogs do not give them any. When you treat a dog as though it is a person and not an animal then it is going to think that it is in fact a person. When you get to the stage that your dog cannot ever be left alone it has gone way too far, and some serious training is in order. We have 2 kelpies and one blue heeler cross, and they are amazing dogs. They love us to bits, but they also live outside. We always walk them, take them away to parks etc. They don't however follow us everywhere, as they are properly trained and looked after. Clearly these dogs that follow you everywhere are not looked after properly or given enough attention, or it is the opposite and they are fed from the table and never disciplined, making them think they are human. Either way that is not correct behaviour
