While it's obvious that Penelope and her pal are having the best day ever, there's more happening in this game than meets the eye. Allowing pets to interact with others like them, especially from a young age, helps to foster their friendly nature which, in turns, makes their lives even happier - just ask Penelope's owner:
"She loves playing with other dogs. She's the most outgoing Italian greyhound anyone has ever seen (so I'm often told)!," Buckmaster tells The Dodo. "Dogs gain SO much from good socialization. Penelope is a perfect example of the benefits of that."
Best of all, it's so much fun to watch.
