Ms. Elton, DO.g.

Unofficial Mascot

Elton is a 6-year-old Blue Heeler/Chihuahua mix, hailing from a wonderful rescue organization in North Carolina. Elton is the epitome of the quote, "every good Behavior Analyst has a bad dog at home". Due to the varying allergies of the individuals we serve, Elton, unfortunately, won't be around the Evoke center much, but she is happiest snoozing away at home, anyway.
