I have a 1 year old toy poodle mix pup. Before I ask the question, I will tell you a little about her. I got her when she was 7 weeks old, from my best friend. She is potty trained, and knows several commands. She is mostly well behaved, except two things. One, is that whenever she hears a little noise or someone knocks and the door, or something, she starts barking like crazy. She wont stop until she finds out what the noise is. And two, is that if she accidently gets out of the fenced yard she runs and runs and wont listen to me. It is really hard to get her. But in the house and in the fenced yard she follows me EVERYWHERE. how do I fix these problems?
