Me, the Mrs & the dog (& Cavvy Spaniel) walking down the street, dog on short lead. A bloke & his kid were coming the other way & he said to his kid, ‘don’t touch that dog, you might catch a nasty disease’
The Mrs didn’t hear him & I didn’t dare tell her!

I don’t get it.

How do you know his kid owned a dog?

You might want to say to your dog loudly “don’t let the small human touch you, you might get zombie syndrome”. 🙄

Don’t see how that’s sarcastic, it’s a parent using the fear factor of disease to keep his child away from your dog. Maybe misleading information to child, but other than that?

Don’t sniff that bloke you might catch stupid.

Try a return of “Don’t bite that one, it doesn’t look healthy.”

I would have said “my dog’s got no nose”, and waited to hear what his response was.

“Nice dog”.

🙄
