I've had her for 3 years now, and she hasn't grown out of her puppy size. My family and I think she was a runt. She was real sick when we got her, but thankfully we got her better. Rosie's only 10 pounds, so I always joke that she's part chihuahua. She so little that I have to watch where I walk and sit, because she tends to blend in with her surroundings. It's funny seeing her in the bed pillows or my sister's stuffed animals, because it's so reminiscent(sp) of E.T. She thinks she's such an attack/guard dog, but it'd be so easy for a robber etc to kick her away. Whenever she's scared, she runs to me, which is cute. She's one of my favorite dogs that I had ever.
