Dog Pox

Little Elijah finished reading his book about dogs to me. "Wow, Elijah! You're a good reader! That was a big dog, huh? Do you like dogs?"
"No, I'm allergic."
"Ah, dogs make you sneeze, huh?"
"No. They make me sick."
"I see."
"Ya... and sometimes they give me Chicken Pox!"
"Woah...."
"No, wait... Dog Pox! And that's way worse than Chicken Pox!"
"Dog Pox, huh? Sounds serious."
"It is! Trust me, you don't want Dog Pox!"
