“Never make snow angels in a dog park”—because of what dogs do on the ground—is a jocular bit of advice that has been printed on many images. “Dear neighborhood kids: Please do not make snow angels in the dog park. Under all that snow there’s tons of dog poop. #southloop” was posted on Twitter by Mananya on February 2, 2011.
   
The saying became popular in December 2015. “Tip of the day: Never make snow angels in a dog park! Just saying” was posted on Twitter by C & R Recovery Solutions on December 15, 2015. “Never make snow angels in a dog park. #DadLife #trustme” was posted on Twitter by John Williams on December 19, 2015.
     
“Don’t eat the yellow snow” is a similar winter saying.

One featured a smiling Allen telling fans, “Never make snow angels . . . in a dog park.”
