Annie, Sam's dog

Sammy and Janet bought these  Chihuahua dogs 2 years past this august. Sam sold his soon after they got them that left Annie , Janet's dog.
That dog is now Sam's dog, she follows along behind him every step he takes. She sleeps in his bed and eats what ever he eats.
Sammy talks to her like she is human. I heard this conversation awhile ago. Sammy said NO,NO I told you not to do that and you went out and did it anyway! I ask what did she do? she had went and rolled in the fresh chicken manure after SAM moved the brooder.
She is pretty smart, see how she has her ears pulled down? that is how she does every time I look at her, she doesn't like me! wonder why?
