I just got a 1 1/2yr old female yorkie and the main problem that I am having is that my dog is aggressive towards other animals. She attacks my cats, barks at my horses and my pot bellie pig. I have told her no in a stern voice and and had to grab her by the scruff of the neck to hold her back. How can I get her to stop being aggressive.

She is a very affection it and loving and very well behaved most of the time, but i love my cats to be around me alot of the times and she will not let them. What can I do to stop this behavior?
