The kind of behavior you describe sometimes happens when a dog feels they are "in charge." The best thing you can do for your little dog is to teach her some obedience commands like sit, stay, come, and down. They are simple but important components to keeping your dog well balanced and secure.
Right now she is feeling that she needs to guard you and protect you. I'm not sure why this has happened but apparently she doesn't feel like you are the protector of the house.
Some good positive reinforcement while teaching her these things will cause her to realize that you are in charge and not her. There are classes you can attend. Sometimes they are not the greatest thing for a dog that is already aggressive toward other animals and people. Maybe you can find a good book or videos if you are not experienced at training. Most of this kind of work needs to be practiced on a regular basis at home anyway.
There is also a website called "dog star daily" where you can learn some good training tips. They also deal with problems people face with their pets. They do have some videos also. |
