While riding his horse one day, a cowboy met an Indian also
riding along.  The Indian had a dog and a sheep following him.
The Cowboy and Indian began a conversation:

Cowboy: "Hey, cool dog you have there - mind if I speak to him?"

Indian: "Dog no talk."

Cowboy: "Hey dog, how's it going?"

Dog: "Doin' alright."

Indian: (look of shock)

Cowboy: "Is this Indian your owner?" (pointing at the Indian)

Dog: "Yep"

Cowboy: "How does he treat you?"

Dog: "Real good. He walks me twice a day, feeds me great food,
and takes me to the lake once a week to play."

Indian: (look of total disbelief)

Cowboy: "Mind if I talk to your horse?"

Indian: "Horse no talk."

Cowboy: "Hey, horse, how's it going?"

Horse: "Cool."

Indian: (extreme look of shock)

Cowboy: "Is this your owner?" (again pointing at the Indian)

Horse: "Yep."

Cowboy: "How's he treat you?"

Horse: "Pretty good, thanks for asking. He rides me regularly,
brushes me down often, and keeps me in a shed to protect me."

Indian: (total look of utter amazement)

Cowboy: "Mind if I talk to your sheep?"

Indian: "Sheep is a liar."
