My next dog will be purchased here in The Netherlands, and sometime next year I will be going back to the states for a few months with it in tow. Sofie I guess you can say was imported, but I purchased her while living in the states and brought her along.
In Westies, I haven't seen anything extremely impressive here (then again I don't go to a lot of shows), so I will probably stick to the states IF I ever get another one.
I have no qualms with importing, there are some breeds I would stick with in the states, and others that I would go looking elsewhere.
