I have a very sweet chihuahua female(2 hers old), I never see this kind the dog sweet like that.
But my Tati that is her name, she is very sweet. My husband and I treat her just like a we treat our daughter.
She is our little baby!
She can not set at the table with us but, she sleep at the bad with us and, some time, my daughter (10 years old) fight for have her in her bed.
