Dog overprotective after stay at a friends place

[dizzydizzy]

My dog would not bark much at strangers and at noises outside. After a stay at a friends place he has started barking a lot at strangers and at any noise and has started behaving very protectively of me. He went from our suburb and quiet house to a downtown and over active neighborhood for a week and started behaving this way after a couple of dyas. He even became protective of my friend as well in the last few days of his stay there . How do i get him calm down and be less protective of me.?

Thanks

This seems to be the case. He probably has changed his role in the household since he came back. I will try your suggestions.
Thanks so much!

Well, he got taken out of his usual routines, and out of his territory, and into a new territory with more noise, more going on, and it probably over-stimulated him.

When you say 'protective of you' do you mean he is clinging to you and growling or something when anyone comes near? Or something like that?
You might have to pull the 'Pack Leader' card out, and start to use some gentle discipline. All the signs are that he's trying to dominate the situation, probably caused by his insecurity. As soon as he sees you are back as Pack Leader again, his insecurity should mellow.
Small signs show a dog who is leader. Various things.
1)Only have him up on your lap on your terms, not his. When YOU feel like it -not him. Don't confuse him by wavering. Stick to the moves you make and be consistent. Make him sit down below you on the floor by gently but firmly 'blocking' him if he tries to get up on to the sofa, for example. Don't follow this straight away by saying "you're a good dog -okay then you can come up now and cuddle me" because that will send mixed messages. Wait until later before you invite him to sit next to you. If he shows any 'protective' signs, get him straight back down on the floor and keep him there.
2) If anyone calls at the door, don't let him rush to the door first. Before you answer, give him firm instruction to 'sit and stay' then answer the door, but keep instructing him to stay back. But keep your voice steady calm and firm. Don't get upset, or annoyed or raise your voice when you do this.  
3) Only give affection when he is relaxed, not when he is hyper in any way.
4) If you go through a doorway or a gateway with him, keep him behind you and make a point of going through that doorway ahead of him. (I used to laugh at this particular discipline, thinking it would make no difference to a dog WHO walked through first, but after seeing the marked effect it had on putting them in their right place, and thus starting to calm them down, I changed my thoughts about it) It shows him in body-language, that you make the decisions, you are the leader. Basically let him see in gentle but assertive and firm ways that you are in charge.

It won't do him any harm to give him a 'pack leader' top-up. It could be that while at your friend's house he didn't get as much normal discipline as he would have got at home, and the routines were different. He's nervy and 'on guard' right now. As soon as he falls back into the certain knowledge that you are in charge again, he won't have to worry so much!
