That's why Betti is so cute to me. I read somewhere that domestic dogs have been genetically modified to maintain a puppyish nature and characteristic s because this appeals to humans. Betti still looks like a pup and she is two years old now. Everyone always asks if she is about a year old. She is also a small rottie. I tell people that and they just laugh, but she is only about 23 inches at the tallest point of her shoulder blade, and that is when she is standing very straight. When she curls up into a ball she is so tiny she fits on my pillow, and often lies there. And those are regular-sized pillows, too, - not the square Euro pillows or long Queen or King-sized. When she's in a ball like that I can just wrap my arms around her and squeeze and I'm only 4'11". Nonetheless, she grunts and is so warm and soft and I love that.
