Seeing Eye Dog

My brother-in-law, the Vet, has a new joke to tell to random strangers that he meets. He bought a book of clean jokes, and claims that most of them are not funny at all. This one was cute, so I will share it with you here:

There were two buddies - one with a German Shepherd and the other with a Chihuahua. The guy with the German Shepherd says to his friend, "Let's go over to that restaurant and get something to eat." The guy with the Chihuahua says, "We can't go in there. We've got dogs with us." The guy with the German Shepherd says, "Just follow my lead."

They walk over to the restaurant. The guy with the German Shepherd puts on a pair of dark glasses and he walks in. The waiter says, "Sorry, sir, no pets allowed." The man with the German Shepherd says, "You don't understand. This is my seeing-eye dog." The waiter apologizes, saying "Come on in."

The guy with the Chihuahua figures, "What the heck," so he puts on a pair of dark glasses and walks in. Once again the waiter says, "Sorry, sir, no pets allowed." The guy with the Chihuahua says, "You don't understand. This is my seeing-eye dog." The waiter says, "A Chihuahua?" The guy with the Chihuahua says, "A Chihuahua??? You mean to tell me, that they gave me a Chihuahua?!"
