Another request made possible by my good friend Superpac13.
This is Denny Cheng, a British-Chinese Corgi puppy (a formerly human boy).
His backstory is similar to that of his best friend Danny Hitachi - an orphaned child prodigy who befriended the Dalmatian family of 101 Dalmatian Street.
In fact, Danny and Denny were in the same orphanage before they went their separate ways.

The two boys reunited not long after Danny became a Dalmatian and was adopted into the Dalmatian family - more specifically, during the events of the episode "All Fired Up".
While Dolly (Danny's adoptive mother) went with her father Doug to the firehouse where he works, Delilah (Dolly's stepmother and Danny's adoptive grandmother) took Danny to the hospital where she works for Take-Your-Kids-To-Work-Day.
Danny, who happens to be friends with the Dalmatian's neighbor Clarissa Corgi, after thinking about Clarissa moping about having no children, decided to use his machine to turn Denny into a Corgi so that he could live with Clarissa as her son.

One thing that makes Denny special is that he's a descendant of Cruella de Vil... from Cruella's side of the de Vil family.

Here is Denny in his Corgi form. Enjoy, everybody!
