My name is Obiwan!

Obiwan is about 5 years old and comes from a very loving family, where he has always been around children and noise. But has most recently been becoming more irritated by the children and becoming a bit snappy with them.
We think he would do best with an adult couple who have experience with animals, with minimal noise and hubbub around their home.
He is a terrier, which means he does have a very large voice and likes to let the world know when there are visitors, people walking by, etc... So full disclosure:he is a little barker.
