ACD are still relatively rare im my country, but the one i met were very fixated on one person, they all had a high ability to focus themself on one task, which is awesome if is training but annoying if it something else.
they were were all very attentive and extremely intelligent.
from the personality they seemed more "directly challenging" and more involved than BCs for example...less sensitive but very capable of standing their ground in a group of dogs. I like how direct they are, but this of course can also have their down sides.
they seemed like you need to be very consistent for them not to test you and since they very active you need to be willing to exercise them mentally and physically so they don't get bored.
