Fear Issues?

[Karen, Jasper and Jackdoodle]

On the subject of behavioral problems, is anyone else here dealing with undesirable behaviors caused by fear issues? Things like barking, lunging, cowering, urinating, etc. because of fear of strangers, noises, etc.?
I have been working with Jack since I got him in January of 2006 on some of these, and recently was asked for ideas to help the foster mom of an extremely fear-aggressive dog. It is hard sometimes to have a dog whose psychological/behavioral problems cause him to act out in ways that others (not knowing his history) view with disapproval. I am wondering if anyone else here has a "special-needs" dog with some of these issues, and if so, what has worked for you in dealing with them?

You are 100% correct....I didn't understand what was meant by the term "socializing". I thought I had done really well making sure she had/has plenty of play dates, family outings, etc. but see now I never really walked her through many scenarios we face. However, she is a city gal so she is fairly comfortable with city sounds and situations....it is hard to tell what will trigger her, and what triggers her one day may not the next. She will be 3 soon, and for the most part I think she is happy. Thanks for your feedback!
