Niko's a very playful happy little handful of a dog but I wouldnt have it any other way. The first night home with getting no sleep, we tryed every trick in the book we finally found one that worked, putting the clock by his bed & letting him fall asleep to the ticking. He is such a sweet boy and we Love him so much. We also renamed him Niko. I cant believe he's already a year & 5 months, time flys. He has grown to be a great dog with a loving personality.
