I was raised with Keeshonden! They are the only breed of dog that I will ever own.

Growing up, my mother showed them (conformation) and bred them. One of our dogs was amazing. He was ranked #2 in the country at one point.
Over the years, we probably had 15 or so. With the exception of one dog, they were all wonderful. (We found out that the one exception had been abused as a puppy.

) The other dogs were so great! They are incredibly family-friendly and loyal. They were always great with us kids. No problems at all.
I agree with the poster who said that they dump their coats twice a year, but otherwise aren't that hard to take care of. They do NOT have to brushed every day. I would imagine that their coats could get pretty matted if they were primarily outside dogs (not that I'd ever advocate that anyway), but otherwise we typically brushed our dogs about once a week. Their coats don't tend to have a "doggy" smell which is really nice too.
They are known as "alarm" dogs (they originally were used as a watchdog of sorts on barges in Holland). So, they will "sound the alarm" (bark) if anyone comes to the door or comes too close to your house, etc. They definitely see the duty of "protecting the family". But they are all bark and no bite.
I lost my 14 year old Kees last year.

She was so wonderful and we all miss her terribly. She was already 7 years old when my first child was born and 10 when my 2nd one was born. She was nothing but wonderful with my children.

She watched over them and loved them. She never once so much as growled at them even when they were toddlers and got a fist of her fur.

We are still heartbroken over losing her and I am far from ready for another dog. It breaks my heart when we lose them. It is almost too painful for me.
I definitely agree with the others to find a reputable breeder. I wouldn't buy one any other way. A good breeder breeds for temperament and health. So, you at least have a good idea that the puppies are starting out on a good footing. You are lucky to live where you do. There are lots of excellent breeders in your region. I know that Ohio has several. Like a PP said, a reputable breeder will require you to have your puppy spayed or neutered if you aren't planning to show it.
Good luck to you! I'm excited for you. Kees puppies are absolutely adorable little furballs. They are little stinkers, but so intelligent. I found them to be extremely easy to train.

Our last dog was trained so quickly using the bell method.
