Jodi...I hope this answers your question:
All of our dogs have different personalities. Some are absolute angels, while others need a little more looking after. I guess it really depends on how you bring a Klee Kai up. Just like any other dog, if you start from the begining telling your pup what is right and what's wrong you won't have a problem with training...but if you wait, you will deffinetly incounter problems. I personally think an AKK would be a great dog for children, they love to sit in a child's lap and cuddle with them...but then they are suckers for belly rubs!
Our smallest Klee Kai is 7 pounds, our biggest is 22, so I guess you could say they are a small breed.
