Have you looked at the Keeshond?
They were originally bred to be "companion" & watch dogs for Dutch barge captains.
They were never bred to be guard or attack dogs or to herd - but to be watch dogs. They are very alert & will bark to let their owners know when someone approaches. However, they are also excellent w/ children & are often used as therapy dogs. (One was used as a therapy dog for the 9/11 rescue workers at Ground Zero.)
They're medium-sized dogs & kinda look a little like overgrown Pomeranians & are the most biddable (not as stubborn) of the spitz dogs.
We have a Keeshond, & his bark is that of a much bigger dog, and he barks whenever anyone that he doesn't know approaches our house. He actually has a very scary bark! (We also have an alarm.) We have a bay window in our living room, & that's one of his favorite places. He likes to stand alert at the window - almost like he's standing at the prow of a ship the way his ancestors did. At night, he *has* to sleep in the hallway outside our bedrooms. We don't make him sleep there, & he normally starts out at the foot of our bed. However, at some point, he gets up & goes into the hallway. It's like instinctively he needs to be where he can see all our bedrooms & keep a watch out all night.
Keeshonden typically train relatively easy. Ours house-trained very quickly! Even w/ all their hair, they only really shed twice a year. Their coat is kept natural, & they only need bathing about once a month. They don't have a doggy odor, & frequent bathing actually hurts their coat. They need to be brushed about once a week. They are also quickly out of the puppy, "chewing everything in sight" stage. They are relatively healthy & have a life span expectancy of 12-15 years.
We love our Maks!
