>Two women were out for a Saturday stroll with their dogs. One had a Doberman and the other had a Chihuahua . As they walked down the street, the one with the Doberman said to her friend, "Let's go over to that bar for a drink."

>The lady with the Chihuahua said, "We can't go in there. We've got the dogs with us."
>The one with the Doberman said, "Just watch, and do as I do." As they walked towards the bar the one with the Doberman put on a pair of dark glasses and started to walk in.

>The bouncer at the door said, "Sorry, lady, no pets allowed."
>The woman with the Doberman said, "You don't understand. This is my seeing-eye dog."
>The bouncer said, "A Doberman is your seeing eye dog?"
>The woman said, "Yes, they're using them now. They're very good."
>The bouncer said, "OK, come on in."
>
>The lady with the Chihuahua thought convincing the bouncer that a Chihuahua was a seeing-eye dog may be a bit more difficult, but thought, "What the heck," so she put on her dark glasses and started to walk in.
>
>Once again the bouncer said, "Sorry, lady, no pets allowed."
>The woman said, "You don't understand. This is my seeing-eye dog."
>The bouncer said, "A Chihuahua?"
>The woman with the Chihuahua said, "A Chihuahua? They gave me a %^&$#$* Chihuahua???"

Very good. :-)

BTW, in the UK we call them "Blind Dogs". It may sound a bit strange to you but, otoh, what the heck else is an eye for but for seeing
