Bella and Sasha's mom says: Sasha and Bella are sisters. Dependant to each other. Opposite of each other, personality wise. Bella is calm, sweet, flower in the wall, loves to cuddle, and Sasha is demanding, independant, a social butterfly. Bella is half Pekingese and half Chihuahua. That is why she is a little bigger than the average Chi-chi. Sasha is a full longhaired Chi-chi. There are two kinds of Chi-chi. But most know only the Taco Bell Chi-chi. There are smoothhaired, which is the Taco Bell Chi-chi, and longhaired Chi-chis like Sasha.
