Aloha,
We had 5, 2 passed. Now we have 3, 1 male and 2 females. One female is 16 months old, Terrible Twos, AKA Destructo dog. All are smart, all have attitude.
They keep the "bad people" in the area honest. They alert at all times of day and night. We think that's why one bad guy (Convicted felon with a record)complained about their barking. Friends said the dogs were chasing away his drug customers and girls working for him in the area.
How smart:

Read the part called "rituals of annoyance" and other things they can do.
Also called "velcro dog" they will stick with you where ever you go and will get in your way. They will kill you with their love(lick you to death).
Smarter than a lot of people, Always Alert, never cheat one, he'll remember it.
Never a dull moment with one. Always fun to watch when they go to "Battle Stations", like watching a cavalry movie when the 2 alphas come charging around the corner at full gallop side by side.
If you have kids, they do NOT like it when other kids get rough with "their" kids. They have been know to bite the "other" kids. Watch out when other kids are around. These dogs take their protection job very seriously.
We have fenced in yard, we do NOT lock our doors at night, this is why:
