Joke

A man takes his Rottweiler to the vet. 'My dog is cross-eyed, is there anything you can do for him?'
'Well,' said the vet, 'let's have a look at him'
So he picks the dog up and examines his eyes, then he checks his teeth. Finally, he says, 'I'm going to have to put him down.' 'What - because he's cross-eyed?'
'No, because he's really heavy'
